ASTM A537 Class 1 normalized carbon-manganese-silicon steel plate

ASTM A537 Class 1 is a heat-treated, normalized carbon-manganese-silicon steel plate used for fusion-welded pressure vessels and structures. It is known for its enhanced yield and tensile strength, making it suitable for pressurized services in the oil, gas, and petrochemical industries, and is often used in boilers and storage tanks requiring good notch toughness.

The material 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.

What is ASTM A537 Class 1 material?

ASTM A537 Class 1 Carbon Steel and Carbon Steel Plates and Carbon Steel Sheet are Engineered to be used in Pressure Vessel applications. The material is a normalised steel and Alloy Steel which is heat treated and as a consequence displays greater yield and tensile strength than the more standard ASTM A516 grades.

What is the difference between ASTM A537 Class 1 and Class 2?

ASTM A537 / ASME SA537 plate material is heat-treated, carbon-manganese silicon steel. A537 Class 1 plate is normalized and Class 2 plate is quenched and tempered. A537 carbon steel plate offers greater tensile strength than ASTM A516. A537 plate is commonly used in Oil & Gas and Petrochemical industries.

What is the yield strength of A537 Class 1?

345 MPa

ASTM A537 Class 1 is a low-carbon, alloy steel plate used for high-pressure vessel applications. This material offers exceptional strength and toughness for high-temperature environments. It boasts a yield strength of 345 MPa and a tensile strength of 485 MPa, making it ideal for use in high-pressure equipment.

What is a 537 CL 1 equivalent to?

The equivalent grades of the ASTM A537 Class 1 Carbon Steel Plates are the DIN 19Mn5 and SPV36 standards.
