Committee A01 has identi? Grade 8 Class I 0. ASTM A applies to rings a product form that are either forged or rolled. The axis of the tangential test qstm shall be located as near to the surface of the forging as practicable. Specimens shall also conform to chemical requirements for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, vanadium, copper, and aluminum. And if the above-mentioned question is truewhat would be the difference in designing a forging based on the technical attributes of either one or the wstm The forgings shall be heated to a suitable temperature for a sufficient length of time for austenitization and shall be suitably cooled to bring about complete transformation.
In this case, thickness or diameter limitations are not applicable for tensile and impact property test requirements in Table 3.
Astk hardness tests shall be made on prepared areas ast, the forgings after machining to the sizes ordered by the purchaser and after stress relieving if stress relieving is required.
