ASTM A565/A565M-10(2025)

Annotation of standard text ASTM A565/A565M-10(2025) :

This guide covers standard specification for hot-finished and cold-finished martensitic chromium steel bars for high-temperature service. The mechanical properties shall be developed by suitable heat treatment, as indicated for each alloy. The steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, molybdenum, vanadium, tungsten, nitrogen, aluminum, columbium, and copper. The microstructure shall not contain more than 5% delta-ferrite after full heat treatment. The material shall conform to the required mechanical properties such as tensile strength, yield strength, elongation, impact strength, and Brinell hardness. The material shall also undergo stress rupture testing using a combination test bar.
