However, one thing is clear-materials are not added in these codes unless the parent specification requires tensile testing to ensure that the product being supplied actually meets the minimum mechanical properties upon which the design is based.

Each casting must be marked qstm a heat number or with a serial number traceable to a heat number. ASTM A was reapproved without changes in A imposes several other requirements that are not included in A nor A Metal melting, metal casting, resin sand casting and green sand casting. Duplex stainless steel is designed to combine improved resistance to stress corrosion cracking including sulfide stress corrosion crackingpitting, crevice corrosion and high strength when compared with other stainless alloys.
