What is ASTM A537?

ASTM A537is a standard specification for pressure vessel plates that are heat-treated. It is widely recognized in the boiler, oil, and gas industries for its strength, toughness, and performance in demanding conditions.

Classification

ASTM A537 is divided into three classes:

• ASTM A537 Class 1: Normalized pressure vessel steel.
• ASTM A537 Class 2: Quenched and tempered for higher strength.
• ASTM A537 Class 3: Enhanced mechanical properties for the most demanding applications.
•

Mechanical Properties by Class

Applications

• Class 1: General pressure vessel use.
• Class 2: High-pressure reactors, petrochemical equipment.
• Class 3: Offshore platforms, power generation equipment.
