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 Class3 carbon 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.
A537 Class3 chemical composition
A537 Class3 mechanical properties
A537 CL3 is under the ASTM standard. There is another material, SA537CL3. SA537CL3 steel is the steel grade in ASME standard. ASME SA573 CLASS 3 steel is also used in pressure vessels. ASME SA537 CL 3 delivery condition is Q&T, means Quenching and Tempering .
