A537 CL1 pressure vessel steel Description

ASTM A537 CL1 pressure vessel steel plate is a carbon manganese silicon steel plate used for fusion welding of pressure vessels and heat treatment of structures. The A537 CL1 pressure vessel steel plate complies with STM A537/537M standard. The equivalent material of A537 CL1 is the national standard Q345R, and the available dimension thickness is 8mm-120mm, and the width is 500mm-4200mm. A537 series are American standard steel plates for pressure vessels, which are divided into three grades: A537CL1, A537CL2 and A537CL3.

ASTM A537 CL1 boiler and pressure vessel steel has good welding performance, high yield strength and toughness. A537CL1 steel plate shall be delivered in normalized state, and is commonly used in petrochemical industry, pressure vessels, large storage tanks, petroleum transportation, liquefied gas tanks, spherical tanks, reactors, reactors, heat exchangers, separators, oil and gas tanks, nuclear reactor pressure shells, boiler drums, high-pressure water pipes of hydropower stations, turbine volutes and other equipment and components.

A537CL1 boiler steel plate grade indicates:

"A": American standard container plate;

"537": the minimum yield point of steel plate is 537, in Mpa;

"CL": the abbreviation of "CLASS";

"1": indicates the grade of steel plate in American standard container.
