Anotace textu normy ASTM A737/A737M-17(2024)e1 :

This specification covers high-strength low-alloy steel plates for service in welded pressure vessels and piping components. This material is particularly intended for piping and pressure vessel applications where high strength and improved toughness are required. Two grades, designated B and C, are covered. The steel shall be killed and shall conform to the fine austenitic grain size requirements specified. The material shall be normalized by heating to a suitable temperature which produces an austenitic structure holding a sufficient time to attain uniform heat throughout the material, and cooling in air. The steel shall conform to the requirements as to chemical compositions specified. The material as represented by the tension test specimen shall conform to the requirements specified.
