Indian Standard RATIONALIZED STEELS FOR THE

AUTOMOBILE AND ANCILLARY INDUSTRY

PART I CHEMICAL COMPOSITION

0. FOREWORD

9.1 This Indian Standard ( Part I ) was adopted by the Indian Standards Institution on 22 June 1979, after the draft finalized by the Co-ordinating Committee on Materials for Automobiles Sectional Committee had been approved by the Structural and Metals Division Council.

0.2 In order to effect variety reduction and to promote economic production of alloy and special steels in the country, IS : 1570-1961* was published as a part of the Steel Economy Programme of Indian Standards Institution. It has served as the basic standard for specifying steel composition in all the Indian Standards relating to material specification. As a further aid to industry, IS1 also attempted industry-wise rationaliza- tion. The list of rationalized steels for the automobile and ancillary industry was prepared as a part of this programme.

The list has been in existence for quite some time. Th,e automobile industry consumes substantial tonnage of steel and it was, therefore, felt that in order to make the list more popular and thereby help the auto- mobile industry to rationalize its requirements within these grades, it should be printed as an Indian Standard. Further, the Government of India through a Gazette Notification issued in 1972 made it compulsory for consumers to place order in terms of 30 categories of Indian Standard steels and also directing the producers to confine the booking of order in terms of these steels.

The list of steels has been reviewed by the concerned Sectional Committee and the foIlowing five additional steels have been included in view of their production, use and application in the automobile industry:

a) 35C16Mo3S15,

b) 46C8Sl0,

c) 42Cr6V 10,

*Schedules for wrought steels for general engineering purposes.

3

16 : 9175 ( Part I ) - 1979

d) 14CrNi6, and

e) 20Ni7CrMo2.

Further the following steels have been deleted: a) C50 because it was felt that the purpose could be served by using

either C45 or C55Mn75, and

b) 16NiCrlMo20 as it coG easily be replaced by 14CrNi6 and also result in saving of molybdenum.

0.3 Accordingly Part I of this standard covering chemical composition of 33 rationalized steels is being brought out. Separate parts covering mechanical properties, hardenability and isothermal transformation characteristics of each of the steels will be published in due course.

0.4 The steels have been included in this list on the basis of their application/tonnage consumed by the automobile and ancillary industry.

1. SCOPE

1.1 This standard (Part I ) covers rationalized list of steels for use by automobile and ancillary industry.

1.1.1 This list does not include the following categories of steels: a) Spring steels,

b) Stainless and heat-resisting steels,

c) Ball-bearing steels, and

d) Tool steels,

2. CHEMICAL COMPOSITION

2.1 The chemical composition of the rationalized steels is given in Table 1. The Indian Standards which cover the detailed requirements for these steels are also indicated in the Table.
