Indian StandardSPECIFICATION FOR

STEEL FOR SPRING WASHERS

(First Revision)o. FOR E W 0 R D

0.1 This Indian Standard ( First Revision) was adopted by the IndianStandards Institution on 15 January 1975, after the draft finalized bythe Wrought Steel Products Sectional Committee had been approved bythe Structural and Metals Division Council.

0.2 This standard was first published in 1967. While reviewing thisstandard it was decided to incorporate two more grades of steel, 055and e60, for spring washers, in this revision.

0.3 Steel spring washers are widely used in railway rolling stock, auto­mobile and other engineering applications where locking action isrequired against rotation of the screwed or bolted assembly.

0.4 For the purpose of deciding whether a particular requirement ofthis 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*. The number of significant places retained inthe rounded off value should be the same as that of the specified valuein this standard.

1. SCOPE

1.1 This standard covers the requirements for steel in the form of plate.sheet, wire or rod intended to be used in the manufacture of springwashers.

2. GRADES

2.1 Steel for spring washers shall be of six grades as specified in Table 1.

3. SUPPLY OF MATERIAL

3.1 General requirements relating to the supply of material shall con­form to IS : 1387-1967t.

4. MANUPACTURE

4.1 Steel shall be made by open-hearth, electric or a combination ofthese processes. In case any other process is employed by the manu­facturer; prior approval of the purchaser shall be obtained.

4.1.1 A sufficient discard shall be made from each ingot to ensurefreedom from injurious piping, undue segregation and other harmfuldefects.

5. CHEMICAL COMPOSITION

5.1 The ladle analysis of steel, when analyzed in accordance withIS : 228-1959·, shall be as given in Table I-

6. FREEDOM FROM DEFECTS

6.1 The material shall have reasonably smooth surface, fre~ from harm·'ful defects.

6.2 Decarburization shall be kept at a minimum. A limit of decarburi­zation may be fixed by agreement between the purchaser and th~

supplier,

7. ROLLING TOLERANCES

7.1 The material shall be supplied to the dimensions specified hy thepurchaser a~d shall be rolled to the following limits:

9. DELIVERY

9.1 The material shall be supplied in anyone of the following conditionssubject to mutual agreement between the purchaser and the manu­facturer:

a) As-rolled.b) As-rolled and annealed, andc) Hardened and tempered.

10. RUST PREVENTION

10.1 The surface of the material may be coated with a thin layer ofanti-rust oil or anti-rust compound when agreed to between the purchaserand the supplier.

11. RETEST

11.1 Should a test piece first selected fail to pass any of the tests specifiedin this standard, two further samples shall be selected for testing inrespect of each failure. Should the test pieces from both these additionalsample pass, the material represented by the test samples shall be deemedto comply with the requirements of that particular test. Should the testpiece from either of these additional samples fail, the material represen­ted by the test samples shall be deemed not to comply with this standard.

12. MARKING AND PACKING

12.1 The material shall be suitably identified with the name or trade­mark of the manufacturer, grade and cast number or by such identi­fication marks by which the steel can be traced to the cast from which ithas been made.
