GSO ASTM A781/A781M:2024 Scope
This specification covers a group of common requirements that, unless covered by the individual product specification in another ASTM document, applies to steel and alloy castings for use in general industrial applications. Materials shall be produced by open-hearth or electric furnace process with or without separate refining, such as argon-oxygen-decarburization (AOD), and then consequently heat treated in the working zone. Castings shall receive heat and product analysis to evaluate their conformance to chemical composition requirements. Mechanical requirements shall also be assessed. The surfaces of castings shall be free of adhering sand, scale, cracks, hot tears, and other surface discontinuities. Repair welding may be performed as required.
