Whereas the Parliament of India has set out to provide a practical regime of right to
information for citizens to secure access to information under the control of public authorities,
in order to promote transparency and accountability in the working of every public authority,
and whereas the attached publication of the Bureau of Indian Standards is of particular interest
to the public, particularly disadvantaged communities and those engaged in the pursuit of
education and knowledge, the attached public safety standard is made available to promote the
timely dissemination of this information in an accurate manner to the public.

COMPARISON OF
INDIAN AND OVERSEAS STANDARDS
FOR WROUGHT STEELS
FOR GENERAL ENGINEERING PURPOSES
0. FOREWORD
0.1 This Indian Standard
was adopted by the
Indian Standards Institution on 15 July 1965, after
the draft finalized by the Alloy Steels and Special
Steels Sectional
Committee
had been approved
by the Structural
and Metals Division Council.
0.3 For ease of reference,
the steels in various
tables ( excluding Tables 1 and 2) are arranged
in the ascending order of maximum carbon content, thus bringing together, as far as possible,
similar compositions.
Further, in selecting Indian
Standard
Steels equivalent- to overseas standard
steels, the actual composition
of steels should be
compared.
Overseas standard steels covering two
or more Indian Standard
steels have been so
indicated in the tables.
0.2 For considerable
time, several requests were
received by IS1 for making available a document
giving equivalent
Indian
Standard
steels for
standard
steels of other countries.
This work,
however, could not be undertaken
until IS1 was
able to formulate a rationalized
list of standard
steels to be used in this country.
As a result of
intensive study and discussions with the important
users and the manufacturers
of steel in this
country, it was possible to publish IS : 1570-1961
Schedules for yTou$ht steels for general engineering purposes.
As .an extension of this work, a
comparison
of I&ian
and overseas standards for
wrought steels for general engineering purposes has
now been compiled.
This comparison
includes
Indian, British, American ( SAE, AISI, ASM and
&TM
),
German
( DIN
and
Werkstoff ),
Japanese
and Russian
Standards
for wrought
steels.
0.4 It will be appreciated
that this standard represents the position with regard to the British,
American, German, Japanese
and Russian specifications existing at the time of publication.
0.5 In the formulation of this standard, considerable assistance
was rendered
to. the Sectional
Committee
by Shri S. Barraclo&gh,
Research
and
Development
Department,
United
Steel
Companies
Ltd, Sheffield ( UK ).
This assistance was made available to the Indian Standards
Institution through the Colombo Plan Council for
Technical
Co-operation
in South and South East
Asia.
