FOREWORD
This Indian Standard (Seventh Revision) was adopted by the Bureau of Indian Standards, after the draft
finalized by the Wrought Steel Products Sectional Committee had been approved by the Metallurgical
Engineering Division Council.
This standard was first published in 1962 and revised in 1969, 1975, 1984, 1992, 1999 and 2006. While reviewing
this standard, in the light of experience gained during these years, the Committee decided to revise it to bring
in line with the present practices being followed by the Indian steel industry, both in the integrated as well as
secondary sectors. The Committee further decided to harmonize the standard with the overseas standards on
carbon-manganese and high strength low alloy (HSLA) of structural steels.
In this revision, the following changes have been made:
a) Title has been modified and the word ‘low’ has been deleted, keeping in view the grades of steel
contained in the standard. Requirements of low tensile structural steel are covered in IS 15911 : 2010
‘Structural steel (ordinary quality) — Specification’.
b) Amendment No. 1 has been incorporated with suitable modifications.
c) Number of basic grades has been changed to nine. A new grade of E275, in line with European Standard,
has been incorporated to take care of the requirements of medium tensile structural steels in the
construction segment. Moreover, for each grade two to four sub-qualities have been introduced,
depending upon the grade, where sub-qualities A, BR, B0 and C, in line with other international standards,
indicate the mode of killing and impact test requirements.
d) The clause on ‘Manufacture’ has been modified, where the scope is suitably widened to include
different steel making and rolling practices in vogue.
e) Silicon content of semi-killed steel has been clearly specified.
For all the tests specified in this standard (chemical/physical/others), the method as specified in relevant
ISO Standard may also be followed as an alternate method.
While revising the standard, assistance has been derived from the following international specifications:
ASTM A 36 : 2008 Specification for structural steel
ASTM A 572 : 2007 Specification for high-strength low-alloy columbium-vanadium structural steel
EN 10025-2 : 2004 Hot rolled products of structural steels
The composition of the Committee responsible for the formulation of this standard is given in Annex A.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with
IS 2 : 1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in
the rounded off value should be the same as that of the specified value in this standard.

3.1 Micro-Alloying Elements — Elements, such as
niobium, vanadium and titanium added singly or in
combination to obtain higher strength to weight ratio
combined with better toughness, formability and
weldability as compared to unalloyed steel of similar
strength level.
3.2 Weldability — A metallic substance is
considered to be weldable by a given process and
for the given purpose, when metallic continuity to a
stated degree can be obtained by welding using a
suitable procedure, so that the joints comply with
the requirements specified in regard to both their
local properties and their influence on the
construction of which they form a part.
3.3 Controlled Rolling — A hot rolling process in
which the temperature of the steel and its reduction
ratio are controlled, particularly during the final
rolling passes, in order to achieve fine grain micro-
structure and optimum mechanical properties.
3.4 Normalizing Rolling — A hot rolling process in
which the final rolling passes are carried out at a
suitable temperature equivalent to normalizing
temperature, followed by cooling in air to a
temperature below the transformation temperature,
in order to produce a structure, analogous to that
obtained by a separate normalizing treatment of hot
rolled product.

9 SELECTION AND PREPARATION OF TEST
SAMPLES
9.1 The position from which test samples are taken
shall be so located in the product as to yield the
clearest possible information regarding properties in
the cross-sectional and longitudinal planes. The
recommended locations for taking test samples for
plates, sections and bars are indicated in Fig.1.
Alternatively, in case of sections, the samples may
be taken from the web. For testing of flat products
like plates tensile and bend test pieces may be cut in
the transverse direction. Selection of location of test
pieces may also be mutually agreed to between the
purchaser and the manufacturer/supplier.
NOTE — However, in case of the plates beyond 12 mm
in thickness, produced from cutting of HR coil, the sample
for tensile testing shall be taken only in transverse
direction.
9.2 Wherever practicable, the rolled surface of the
steel shall be retained on the two opposite sides of
the test samples.
9.3 In case of flat test samples for tensile test, both
surfaces are normally to be left on the test samples
for strips and plates up to 32 mm thick. At least one
rolled surface shall be left on rectangular test
samples taken from plates exceeding 32 mm in
FIG. 1 STRUCTURAL STEEL SECTIONS, POSITION AND ORIENTATION OF SAMPLE
IS 2062 : 2011
6
thickness. Round test samples are permitted, but
should only be adopted for thickness exceeding
20 mm.
9.4 In case of flats up to 16 mm thick, the test sample
shall undergo, if possible, no machining whatever,
prior to use as a test piece. If this is not possible, the
test sample shall undergo the minimum amount of
machining.
9.5 Bars below 28 mm shall be tested without
machining. In case of bars having diameters or
thickness between 28 mm and 71 mm, the bars may
be symmetrically reduced by machining. For bars
having diameters or thicknesses exceeding 71 mm,
the test sample may be taken from the position shown
in Fig. 1.
9.6 In case of plates, strips, sections and flats, bend
tests shall be carried out on rectangular test samples
which as far as possible should be of the full
thickness of the product. In case of plates, sections
and flats exceeding 28 mm in thickness, it is
permissible to remove metal from one side of the test
sample before using it as a test piece. The rolled
surface of the test piece shall be on the outer side of
the bend during the test.
9.7 Before test samples are detached, full particulars
regarding cast number, size and mass of plates,
strips, sections, flats and bars in each cast shall be
furnished by the manufacturer to the purchaser. In
case of plates the number of plates in each cast shall
also be given.
9.8 Test samples shall be cut in such a manner that
the deformation is avoided as far as possible. If
shearing of flame-cutting is employed, an adequate
allowance shall be left for removal by machining.
9.9 Test samples shall not be subjected to heat
treatment unless the material from which they are
cut is similarly and simultaneously treated with the
material before testing. Any slight straightening of
test samples which may be required shall be done
cold.
10 TENSILE TEST
10.1 Number of Tensile Tests
Number of test samples shall be 2/cast/heat and a
class of steel product irrespective of cast/heat size.
10.2 Tensile Test Pieces
The tensile strength, yield strength and percentage
elongation of steel shall be determined from standard
test pieces cut crosswise from plates and strips and
lengthwise from sections, flats and bars. The test
shall be carried out as on the standard test pieces
prepared in accordance with IS 1608.
10.2.1 As a rule, test pieces with a proportional
gauge length complying with the requirements
L
o
= 5.65 should be used for the tensile test, where
L
o
is the gauge length and S
o
is the cross-sectional
area of the test piece.
10.2.1.1 Test pieces with a non-proportional gauge
length, other than 5.65
may be used in which case
the elongation values shall be converted to 5.65
in accordance with IS 3803 (Part 1).
10.3 Tensile Test
Yield strength, tensile strength and percentage
elongation, when determined in accordance with
IS 1608, shall conform to the requirements as given
in Table 2.
10.3.1 In case of sections, the thickness of which is
not uniform throughout the profile, the limits of sizes
given in Table 2 shall be applied according to the
actual maximum thickness of the piece adopted for
testing.
10.3.2 Should a tensile test piece break outside the
middle half of the gauge length (see IS 1608) and the
percentage elongation obtained is less than that
specified, the test may be discarded at the
manufacturer/supplier’s option and another test
made from the sample plate, strip, section, flat or bar.
11 BEND TEST
11.1 Number of Bend Test
Number of bend test shall be 2/cast/heat
Class of Steel Product Direction of Bend Tests
Plates strips Crosswise
Sections Lengthwise for each type
Flats and bars (round Lengthwise
hexagonal, etc)
11.2 Bend Test Piece
The test pieces shall be cut crosswise from plates
and strips and lengthwise from sections, flats and
bars. When section permits, these shall be not less
than 40 mm wide. If the manufacturer/supplier so
desires, round, square, hexagonal and flat bars and
structural sections shall be bent in the full section
as rolled.
11.2.1 In all bend test pieces, the rough edge arises
resulting from shearing may be removed by filing or
grinding or machining but the test pieces shall
receive no other preparation.
11.3 Bend Test
Bend test shall be conducted in accordance with
IS 1599.
11.3.1 For bend test, the test piece at room
IS 2062 : 2011

FIG. 2 MINIMUM IMPACT ENERGY VALUES FOR TEST PIECES WITH A WIDTH BETWEEN 5 mm AND 10 mm
temperature shall withstand bending through 180
o
to an internal diameter not greater than that given in
Table 2 without cracking.
12 IMPACT TEST
12.1 Impact test shall normally be carried out on
products having thickness/diameter greater than or
equal to 12 mm. The test specimen is parallel to the
direction of rolling and the base closer to the rolled
surface is more than 1mm from it. The notch axis shall
be perpendicular to the rolled surface.
12.1.1 If stated in the order, impact tests may be
carried out on products having a thickness less than
12 mm, the dimensions of the test pieces shall be in
conformity with IS 1757. The minimum impact energy
values of reduced sizes shall be as shown in Fig. 2
for grades E 250, E 275, E 300, E 350. For other grades,
the values shall be reduced in direct proportion to
the cross-sectional area of the test piece.
12.2 This test is carried out using a V-notch test
piece (see IS 1757) the value for consideration being
the arithmetic mean of the results obtained on three
test pieces taken side by side from the same product
(see Table 2).
12.3 The test sample shall be taken from the thickest
product. If the test sample taken from the thickest
product rolled from a cast meets the requirements,
the whole cast shall be deemed to meet the
requirements of the test, if not, the test shall be
performed on a section of next lower thickness rolled
from same cast, if it meets the requirements specified,
this particular thickness as also other sections of
lower thickness shall be deemed to satisfy this
specification. If this thickness also does not meet
the requirements, the test shall be carried out on the
next lower thickness and so on, because the
toughness of the product will be dependent on the
rolling direction as well as on the section size.
12.3.1 One test sample shall be taken from thickest
product per cast/heat.
12.4 The material represented shall be deemed to
comply with this standard, if the average value of 3
test specimens, meets the requirements given in
Table 2 provided no individual value shall be less
IS 2062 : 2011
8
than 70 percent of the specified value. If the average
value of the three Charpy impact tests fails to comply
by an amount not exceeding 15 percent of the
specified minimum average value, three additional
test pieces from the same sample shall be tested and
the results added to those previously obtained and
a new average calculated. Provided this new average
complies with the specified requirement, the material
represented shall be deemed to comply with this
standard.
13 Y GROOVE CRACKABILITY TEST
Y groove crackability tests may be carried out in
accordance with IS 10842 for products of only Grade
E 250 C material having thickness 12 mm and above,
if specifically agreed to between the purchaser and
the manufacturer/supplier.
NOTE — The Y groove crackability test will not be
applicable for rounds and it is mainly for plates and
sections.
14 OTHER TESTS
14.1 The material may be subjected to non-
destructive testing to determine the soundness of
material subject to mutual agreement between the
purchaser and the manufacturer/supplier.
14.2 Metallurgical tests for grain size, directionality,
inclusion content may be carried out subject to
mutual agreement between the purchaser and the
manufacturer/supplier.
15 DIMENSIONS
Unless otherwise agreed to between the purchaser
and the manufacturer/supplier, the nominal
dimensions of rolled products conforming to this
standard shall be in accordance with the relevant
Indian Standard. Currently available Indian Standard
are listed in Table 4.

steel products conforming to this standard shall be those
specified in IS 1852 except for parallel flange beams and
columns covered by IS 12778 for which the tolerances
shall be as per IS 12779. Other tolerances may be
followed within the total tolerance range as specified in
IS 1852 and IS 12779 as applicable.
17 RE-TESTS
17.1 If a test does not give the specified results, two
additional tests shall be carried out at random on the
same lot. Both retests shall conform to the requirements
of this standard; otherwise, the lot shall be rejected.
17.2 Re-heat Treatment
If any heat treated material fails to meet the mechanical
requirements specified, the supplier may re-heat treat
the material and in that case, all mechanical properties
shall be re-evaluated.
18 CALCULATION OF MASS
The mass of steel shall be calculated on the basis that
steel weighs 7.85 g/cm

.
19 DELIVERY
Subject to prior agreement between the purchaser and
the manufacturer/supplier, suitable protective treatment
may be given to the material after rolling.
20 MARKING
20.1 Each product, with the exception of round, square
and hexagonal bars and flats, shall carry a tag or be
marked with the manufacturer’s name or trade-mark. Bars
and flats shall carry a tag bearing the manufacturer’s
name or trade-mark. Designation of steel should also
be similarly marked on the product or tag.
20.2 Every heavy, medium structural mill and plate mill
product shall be marked with the cast number. Plates
produced from strip in coil form shall be marked with
cast/heat number on top plate of each pile/packet.
20.3 The ends of the rolled products shall be painted
with a colour code, as agreed to between the purchaser
and the manufacturer/supplier.
