ASTM A516 Gr 55 A516M grade 55 pressure vessel steel plate

ASTM A516 Gr 55 (A516M grade 55) is a common low-carbon steel pressure vessel steel plate used to manufacture pressure vessels and boilers at low to medium temperatures.

1. Chemical composition: The typical chemical composition of A516 Gr 55 includes elements such as carbon (C) up to 0.18%, manganese (Mn) ranging from 0.55% to 0.98%, sulfur (S) up to 0.035%, and phosphorus (P) up to 0.035%.

2. Mechanical properties: A516 Gr 55 steel plate usually has good ductility and toughness, exhibits high strength and weldability at room temperature, and is suitable for conventional pressure vessel applications.

3. Standard compliance: Complies with ASTM A516/A516M standard, which covers the requirements for carbon steel pressure vessel materials used under low to moderate temperature and pressure conditions.

4. Application areas: A516 Gr 55 is commonly used in the chemical, petroleum, and natural gas industries for the production of pressure vessels, storage tanks, pipelines, and other equipment, ensuring its stable and reliable performance under general working conditions.

By selecting pressure vessel steel plates that comply with ASTM A516 Gr 55 (A516M grade 55) standards, it is possible to ensure that the manufactured equipment meets relevant standard requirements, provides a safe and reliable operating environment, and meets the strict quality and performance requirements of the industrial field.
