Mechanical Property Requirements 8. In these cases, mechanical property requirements shall be subject to agreement between the purchaser and the manufacturer.

In addition, heat numbers, or serial numbers that are traceable to heat numbers, shall be marked on all pressurecontaining castings individually weighing 50 lb Pressure-containing castings weighing less than 50 lb Marking shall be in xstm a position as not to injure the usefulness of the casting.

Each continuous casting from which the test bar was taken shall be identi? If all of the test bars from the initial sampling meet the requirements, the lot shall be acceptable. The fractured bars shall be retained for chemical veri?

In determining copper minimum, copper may be calculated as copper plus nickel. C in the heat-treated condition will not be attained if the lead content exceeds 0. F Chromium content shall be 0. G Iron content shall not exceed nickel content. Other major element chemical requirements: H Chemical requirements for other elements: When castings are produced from alloy ingots of known composition, the sampling interval may be raised to one sample for each lb kg of continuous production of the lot.

This sample may be taken before mechanical straightening. Test bar specimens shall be positively identi? Where castings are heat treated, test bar specimens shall be heat treated with the castings they represent. Each continuous cast bar from which the test bar was taken shall be identi?
