ASTMA537 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.
