A537 Class2(A537CL2) pressure vessel steel plate is a kind of high strength, high toughness, corrosion resistant pressure vessel steel plate, its chemical composition mainly includes iron, carbon, silicon, manganese, phosphorus, sulfur and other elements. The content of carbon is generally between 0.20% and 0.27%, the content of silicon is between 0.15% and 0.40%, and the content of manganese is between 0.80% and 1.20%. The precise ratio of these chemical components makes A537 Class2(A537CL2) steel plate have excellent mechanical properties and weldability.

2.Mechanical Properties

A537 Class2(A537CL2) Steel plate for pressure vessels has excellent mechanical properties. Its tensile strength is usually above 600MPa, and its yield strength is above 400MPa. In addition, the elongation of the steel plate is high, generally greater than 20%, which makes the steel plate not easy to break when subjected to complex stresses. This excellent mechanical property makes A537 Class2(A537CL2) steel plate can meet the manufacturing requirements of various high strength pressure vessels.

3.Heat Treatment State

In order to further improve the mechanical properties and corrosion resistance of A537 Class2(A537CL2) steel plate, high temperature tempering treatment is usually required. After heat treatment, the internal structure of the steel plate is more uniform, and its tensile strength and yield strength are further enhanced. In addition, heat treatment can also improve the heat resistance and corrosion resistance of the steel plate, so that it can adapt to a variety of harsh working environments.

4.Low Temperature Impact Test

In order to ensure that A537 Class2(A537CL2) steel plate can still maintain good performance in low temperature environment, low temperature impact test is needed. This test tests the steel plate's ability to resist impact at low temperatures, ensuring that it maintains a high fracture resistance in extremely cold environments. This characteristic makes the A537 Class2(A537CL2) steel plate particularly suitable for the manufacture of pressure vessels that need to work at low temperatures.

 5. Main Application Scenarios

Because A537 Class2(A537CL2) steel plate has excellent properties such as high strength, high toughness and corrosion resistance, it is widely used in the manufacture of various pressure vessels. For example, in the field of petrochemical industry, the steel plate is often used in the manufacture of storage tanks, reactors, pipelines and other key equipment; In the field of energy, it is used to manufacture key components such as pressure shells and boilers for nuclear reactors; In the aerospace sector, it is used to manufacture key equipment such as aircraft hydraulic system components.
