Annotation of standard text ASTM A356/A356M-26 :

This specification covers one grade of martensitic stainless steel and several grades of ferritic steel castings for cylindrical (shells), valve chests, throttle valves, and other heavy-walled castings for steam turbine applications. The steel shall be made by the open-hearth or electric-furnace process. Deoxidation of the carbon and low-alloy steel grades shall be by manganese and silicon. The castings shall be heat treated in either the normalized, tempered, or stress-relieved conditions. Mechanical properties such as tensile strength, yield strength, and elongation shall be determined by subjecting the specimens to a tension test.
