ASTM A216 WCC PDF

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.

Scope 1. Selection will depend upon design and service conditions, mechanical properties, and the high-temperature characteristics. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

ASTM A216 Propriedades Mecânicas e Composição Química

A is forged carbon steel per ASME material group 1. The chemical composition for each material is essentially the same low carbon steel but there may be some very minor differences in exact ranges of minor elements. Get copies of both material specifications and check them out for yourself. What size valve are you trying to buy? What is the fluid service and design conditions of your application? If you are purchasing a commercially mass produced valve then you will be subject to what the valve manufacturer produces or has in stock. If you are buying a valve larger than 2" NPS then you are generally going to get a cast body.
