The ASTM A537 is the standard specification for heat-treated carbon Manganese-Silicon steel plates intended for pressure vessel plates. Some applications of this specification are pressure vessels designed for medium and lower-temperature service, asking for supreme notch toughness also for API 620 and API 650 storage tanks. This specification is available in various categories, namely, Class 1, Class 2, Class 3, and so on. ASTM A537 CL. 2 Plates are available as quenched and tempered plates. Actual temperatures and times for tempering are carefully chosen for each composition. The maximum thickness of plates allowed as per this specification for Class 2 is 6 inches. This specification has features like high strength, toughness and flexibility, and off-course excellent malleability, which makes it suitable for industrial machinery, textile machinery, cement companies, etc.

Specifications : ASTM A537 / ASME SA537
Grade : ASME SA 537 CL.2 Boiler and Pressure Vessel Steel Plates
Thickness : 5mm-150mm
Width : 1000mm-4500mm
Length : 3000mm-18000mm
Impact tested : -52° C
Tempering : Notch toughness can be improved by quenched cooling from hot rolling or normalizing by the supplier. If such a faster cooling rate is agreed upon between purchaser and supplier then the steel is also to be tempered at 1200 F.
