ASTM A216 / A216M - 08

Standard Specification for Steel Castings, Martensitic Stainless and Alloy, for Pressure-Containing Parts, Suitable for

High-Temperature Service

This specification covers carbon steel castings for valves, flanges, fittings, or other pressure-containing parts for

high-temperature service and of quality suitable for assembly with other castings or wrought-steel parts by fusion

welding. Covered here are three grades of carbon steel (Grades WCA, WCB, and WCC), the selection of which shall

depend on the design and service conditions, mechanical properties, and the high temperature characteristics.

Castings shall be heat treated and furnished, as appropriate to their design and chemical composition, in the

annealed, or normalized, or normalized and tempered conditions after they have been allowed to cool below the

transformation range. Furnace temperatures for heat treating shall be effectively controlled by pyrometer. Steel

castings shall adhere to chemical composition and tensile property requirements, which include tensile strength,yield strength, elongation, and reduction of area. The surface of castings shall be free of adhering elements such as

sand, cracks, hot tears, and other discontinuities, and as such be repair welded when judged appropriate.
