What’s the Difference Among A537CL1, A537CL2, and A537CL3 steel

Divided into three levels, ASTM A537 steel has steel grades,namely A537CL1, A537CL2, A537CL3. Sometimes written in SA537CL1, SA537CL2, SA537CL3, SA is written in the ASME standard S means asme, A means ferrous metal, similar to ASTM.

A537CL2 steel is a heat-treated carbon-manganese-silicon steel plate for American standard pressure vessels, A537 Class 2 steel equivalent to Q345R (old 16MnR) in Chinese Standard.
A537CL1, A537CL2, A537CL3 container plates Origin: Katalor, performing standard ASTM A537.

The delivery status of A537CL1 plates is normalized flaw detection and low temperature impact.
A537 Class 2 steel, A537 Class 3 steel delivery status: quenching + tempering, detecting low temperature impact. Ultrasonic flaw detection: Ultrasonic flaw detection can be carried out according to user requirements.

A537CL1, A537CL2, A537CL3 steel chemical composition (%):
C≤0.24, Mn0.7-1.6, S≤0.035, P≤0.035, Si0.15-0.5, Ni≤0.25, Cr≤0.25, Mo≤0.08
Mechanical properties of A537CL1, A537CL2, A537CL3 steel:
CL.1 normalizing ≥345 485-620 22
CL.2 quenching + tempering ≥ 415 550-690 22
CL.3 Quenching + Tempering ≥380 550-690 22
A537CL1, A537CL2, A537CL3 plate low temperature impact

A537CL1, A537CL2, A537CL3 steel plates are mainly used in coal mine chemical, spherical tank boiler manufacturing. ASTM A537 plate is widely used in petroleum, chemical, power station, boiler and other industries. It is commonly used to produce reaction heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler steam drums, liquefied petroleum gas cylinders, hydropower stations. Water pipes, turbine volutes and other equipment and components.
