Foundry and Steel Casting Sectional Committee, MTD 14

FOREWORD

This Indian Standard (Fourth Revision) was adopted by theBureau of Indian Standards, after the draft finalized by the

Foundry 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 the

standard in the light of the experience gained during these years, the committee decided that the standard may be

further 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 1and chemical composition of some of the grades have been

modified; and

b) Table 2 and Table 3 have been modified.

Castings ofmartensitic stainless steel and alloy steel for valves, flanges, fittings and other.pressure containing parts and

of quality generally suitable for assembly with other castings or wrought steel parts by fusion welding are covered by

this specification. It is not intended to imply that the steels specified in this standard possess equal degree ofweldability.

Therefore, it is the responsibility of the purchaser to establish for himself the suitable welding technique. Since these

grades possess varying degrees of suitability for resistance to corrosion and high temperature service, it is also the

responsibility 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 specified

in 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 steelcastings for pressure purposes issued by the British Standards Institution

ASTM A 217/A 217M-200 1 Martensitic stainless steel and alloy steel castings for pressure containing parts

suitable 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 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.

12.3 The test pieces shall be heat-treated along with the

castings they represent.

13 MECHANICAL TESTS

13.1 The mechanical properties specified are those which

are to be obtained from test bars cast either separately

from or attached to the castings to which they refer and

heat-treated as given in 12. The test values so exhibited,

therefore, represent the quality of steel from which the

castings have been poured; they do not neces-sarily

represent the properties of the castings themselves.

13.2 In the case of a special or large casting or in other

cases, the purchaser may speciQ at the time of enquiry

and order, that the test, bar be cast attached to the casting

from which the mechanical tests are to be conducted. The

purchaser shall show the size and location of such an

attached test bar on the drawing, in the absence of which

the manufacturer may use his discretion in this regard.

13.2.1Sucha test bar shallnot be detached from.the casting

until the heat-treatment of the casting is over and it has

been stamped by the purchaser.

13.3 The tensile test shall be carried out in accordance

with IS 1608. The relevant mechanical properties shall be

as given in Table 3.

13.4 If specified in the enquiry and order the impact test

shall be carried out in accordance with IS 1757 and the

values obtained shall conform to the requirements given

in Table 3.

13.5 Bend Test

Bend test pieces shall be of suitable length, convenient

for the machine on which they will be bent and shall have

either a diameter of 25 mm or rectangular section of

25

x

20 mm. The edges of the rectangular test piece shall

be rounded to a radius of not more than 1.5 mm and the

test shall bemade by bending the test piece over the thinner

section in accordance with IS 1599.

14 NON-DESTRUCTIVE TESTS

14.1 Non-destructive testing shall be applied if so

specified in the.enquiry and the order. Under this heading,

the tests are grouped which aim at revealing defects that

cannot be revealed by a simple visual examination, such

as dye penetrant, magnetic particle, ultrasonic,

X-radiographic, or gamma-radiographic inspection; also

included under this heading are tests on the surface

condition by visual or visual-tactile examination. The

purchaser shall speci@ in the enquiry and order:

a)

b)

c)

-d)

e)

The type of non-destructive testing which he intends

to carry out or to have carried out;

The area or areas of the casting towhich these tests

apply, and the type of discontinuity, where relevant

Whether all, or what proportion, of the castings are

to be tested;

The severity level defining the acceptability or

non-acceptability of defectswhich maybe revealed;

and

Whether the manufacturer is or isnot contractually

responsible for carrying out the tests.
