A 537 Class 1carbon steel plates are engineered to be used in pressure vessel applications.A537 Class 1 steel plates shall be normalized in all of thickness. A 537 steel material usual be serviced the Gas, Petrochemical and Oil industry. The material of ASTM A537 Class 1 is a normalised steel which is heat treated and as a consequence displays greater yield and tensile strength than the more standard ASTM A516 grades. The steel is ideal for use in pressurised service both in boilers and pressure vessels and Masteel UK Limited supplies A537 Class 1 plates to the world's leading fabricators who in turn serve the Oil, Gas and Petrochemical industry.

Key Properties:
Chemical Composition: A537 Class 1 Carbon Steel Plate typically contains carbon, manganese, phosphorus, and sulfur, with a focus on specific ranges to achieve desired mechanical properties.
Mechanical Properties:
Yield Strength: Minimum yield strength of 265 MPa (38,000 psi) for class 1 plates; the yield strength increases for higher classes.
Tensile Strength: Ranges from 450 MPa (65,000 psi) to 620 MPa (90,000 psi) based on the class of the plate.
Elongation: Minimum elongation is around 21% in 200 mm, indicating good ductility.
