A537 Pressure Vessel Steel Plate

ASTM A537 pressure vessel steel plates are heat treated carbon manganese silicon steel plates used in pressure vessel fabrication. There are 3 grades, which are Grade 1, Grade 2, and Grade 3.


ASTM A537 pressure vessel steel plates, as a high-strength, high-quality steel, is widely used in petroleum, chemical industry, pressure vessels and other fields. The strength of A537 is much higher than that of ordinary steel, and it can maintain excellent stability in high-pressure and high-temperature environments. After special anti-corrosion treatment, A537 steel plate has extremely strong corrosion resistance and can adapt to various harsh environments. Besides, A537 steel is easy to solder, reducing product damage caused by soldering problems.

Scope of Application

ASTM A537 boiler vessel plate is a steel plate used when the yield strength and tensile strength of ASTM A516 cannot meet the requirements of pressure equipment such as boilers and pressure vessels in the oil, natural gas, and petroleum industries. ASTM A537 boiler vessel plate has good notch toughness, which is widely used in API 650 and API 620 storage tanks, medium and low temperature pressure vessels, etc.
