Specification :

ASTM A537 CL3 Weldable normalized fine grained pressure vessel steels
Key words :
ASTM A537 CL3 steel plate/ sheet, ASTM A537 CL3 steel plate/ sheet, under ASTM standard, we can regard A537 CL3 steel plate/ sheet for simple pressure vessels steel.

A537 Class3carbon steel plates are engineered to be used in pressure vessel applications. Steel plate A 537 CL3 is a quenched and tempered steel material, the same with A 537 CL2 in heat treatment. Although the A 537 CL3 only yields strength lower than A 573 CL2, the two grade have a little different in price. A 537 cl3 quenched and tempered temperature is 620, and A 537 cl2 is 595.

ASTM A537 CL3 steel Chemical Composition % :
Main chemical composition in ASTM A537 CL3 steel: Carbon max 0.24, Manganese from 0.64 to 1.46, Sulphur max 0.035, Phosphorus max 0.035, Silicon from 0.13 to 0.55, More detailed information, please refer to the flowing table:

ASTM A537 CL3 steel Mechanical Properties
A537 CL3 this material is mainly used to fabricate boiler and pressure vessel. So , same the other boiler and pressure vessel using steel plate, this kind of steel has the good grain and Mechanical properties. It' s yield strength is between 275- 380 MPa ( there is different min strength point at the different thickness.) A537 CL3 tensile strength is from 485MPa to 690MPa. ( different min strength point at the different thickness.) More detailed information about ASTM A537 CL3 steel Mechanical Properties , please refer to the following table:
