Anotácia textu normy ASTM A990/A990M-23 :
This specification covers iron-nickel-chromium and nickel alloy castings specially processed with restricted melt practices, weldability testing, and nondestructive examination (NDE) requirements for use in pressure retaining parts with corrosive service environments. The choice of manufacturing procedure to be used for producing the alloy castings shall be according to specified metallic contents. Materials shall conform to specified chemical composition and tensile property requirements, and weldability qualifications. Nondestructive examination requirements such as casting thickness shall be evaluated by visual, radiographic, and liquid penetrant inspection. Castings shall be repair welded and solution heat treated prior to final cleaning by blasting, and shall not be peened, plugged, or impregnated.
