FOREWORD

This Indian Standard (Fourth Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by theFoundry and Steel Casting Sectional Committee had been approved by the Metallurgical Engineering Division Council.

This standard was first published in 1965 and was subsequently revised in 1974, 1983 and 1992, While reviewing thestandard in the light of the experience gained during these years, the committee decided that the standard may befurther revised. In this revision, various clauses have been aligned with the recent standards on steel castings.

In this revision following modifications have been made:

a) Four new grades have been added in Table 1 and chemical composition of some of the grades have beenmodified; and

b) Table 2 and Table 3 have been modified.

Castings of martensitic stainless steel and alloy steel for valves, flanges, fittings and other.pressure containing parts andof quality generally suitable for assembly with other castings or wrought steel parts by fusion welding are covered bythis specification. It is not intended to imply that the steels specified in this standard possess equal degree of weldability.Therefore, it is the responsibility of the purchaser to establish for himself the suitable welding technique. Since thesegrades possess varying degrees of suitability for resistance to corrosion and high temperature service, it is also theresponsibility of the purchaser to determine which of the grades is suitable for the actual service requirement.

For the benefit of the purchaser, information regarding typical uses of different grades of alloy steel castings specifiedin the standard has been given in Annex A.

In the preparation of this standard, assistance has been derived from the following publications:

EN 1504:1976 ‘Specification for steel castings for pressure purposes’ issued by the British Standards Institution

ASTM A 217/A 2 17M-200 1 ‘Martensitic stainless steel and alloy steel castings for pressure containing partssuitable for high-temperature service’, issued by the American Society for Testing and Materials

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value observedor calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2: 1960 ‘Rules forrounding off numerical values (revised)’. The number of significant places retained in the rounded off value should bethe same as that of the specified value in this standard.

12.3 The test pieces shall be heat-treated along with thecastings they represent.

13 MECHANICAL TESTS

13.1 The mechanical properties specified are those whichare to be obtained from test bars cast either separatelyfrom or attached to the castings to which they refer andheat-treated as given in 12. The test values so exhibited,therefore, represent the quality of steel from which thecastings have been poured; they do not neces-sarilyrepresent the properties of the castings themselves.

13.2 In the case of a special or large casting or in othercases, the purchaser may speciQ at the time of enquiryand order, that the test, bar be cast attached to the castingfrom which the mechanical tests are to be conducted. Thepurchaser shall show the size and location of such anattached test bar on the drawing, in the absence of whichthe manufacturer may use his discretion in this regard.

13.2.1 Such a test bar shall not be detached from.the castinguntil the heat-treatment of the casting is over and it hasbeen stamped by the purchaser.

13.3 The tensile test shall be carried out in accordancewith IS 1608. The relevant mechanical properties shall beas given in Table 3.

13.4 If specified in the enquiry and order the impact testshall be carried out in accordance with IS 1757 and thevalues obtained shall conform to the requirements givenin Table 3.

13.5 Bend Test

Bend test pieces shall be of suitable length, convenientfor the machine on which they will be bent and shall haveeither a diameter of 25 mm or rectangular section of25 x 20 mm. The edges of the rectangular test piece shallbe rounded to a radius of not more than 1.5 mm and thetest shall be made by bending the test piece over the thinnersection in accordance with IS 1599.

14 NON-DESTRUCTIVE TESTS

14.1 Non-destructive testing shall be applied if sospecified in the.enquiry and the order. Under this heading,the tests are grouped which aim at revealing defects thatcannot be revealed by a simple visual examination, suchas dye penetrant, magnetic particle, ultrasonic,X-radiographic, or gamma-radiographic inspection; alsoincluded under this heading are tests on the surfacecondition by visual or visual-tactile examination. Thepurchaser shall speci@ in the enquiry and order:

a)

b)

c)

-d)

e)

The type of non-destructive testing which he intendsto carry out or to have carried out;

The area or areas of the casting to which these testsapply, and the type of discontinuity, where relevant

Whether all, or what proportion, of the castings areto be tested;

The severity level defining the acceptability ornon-acceptability of defects which maybe revealed;and

Whether the manufacturer is or is not contractuallyresponsible for carrying out the tests.
