3.ASTM A537 CL3 Application

ASTM A537 CL3 steel plates are engineered to be used in pressure vessel applications.Steel plate ASTM A537 CL3 is a quenched and tempered steel material, the same with A 537 CL2 in heat treatment.Although the ASTM A537 CL3 only yields strength lower than A 573 CL2, the two grade have a little different in price. ASTM A537 CL3 quenched and tempered temperature is 620, and A 537 CL 2 is 595.
