MODUK DEF STAN 13-47 PDF

This Standard describes the requirements for the supply and inspection of steel for shell bodies and proof shot used in the as-forged, as rolled or normalised, normalised, hardened and tempered condition. The supply conditions have previously been rationalised to reflect current and future requirements by the deletion of Cold Drawn and Lead Bearing Steels.

Both ingot and continuously cast steel are covered by the standard.

A schedule of compositions and properties of the steel is contained in Tables 1 to 6.

Conditions which may be demanded when the steel is required for use in specialized forging plant are included in Annex A.

With the exception of units for IZOD impact values (for which, in agreement with current BSI practice, imperial units are retained), metric units are used throughout the Standard and, where quoted, shall regarded as standard.
