ASTM A573Gr70 Carbon Steel Description

A573Gr70 carbon low-alloy steel plate under ASTM A573/573M-05 standard of the American Society for Testing and Materials. ASTM A573 steel also has two quality grades of 58 and 65 under the same standard. ASTM A573 Grade70 carbon steel plate has good impact resistance, small temperature deformation, and good welding performance. Good, microalloyed, high purity, low carbon equivalent, strong resistance to hydrogen sulfide.

ASTM A573Gr70 carbon and low-alloy steel is widely used in petroleum, chemical industry, power station, boiler and other industries to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums , liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, water turbine volute and other equipment and components.

A573 Grade70 boiler steel is a carbon-manganese-silicon steel plate, which is mainly used to improve the notch resistance at room temperature. Usually delivered in a normalized state. A573Gr70 plain carbon steel plate is a steel plate for American standard pressure vessels. It is often used in pressure vessel reels or in the manufacture of other petrochemical machinery and equipment, such as flanges, heads, and pipes that match pressure vessels.
