Hot rolled A302Gr.C alloy steel plate

A302Gr.C steel plate belongs to Mn-Mo and Mn-Mo-Ni alloy steel plates for pressure vessels. A302Gr.C implements ASTM A-302 / A-302M-2015 (standard American Society for Testing and Materials) A302Gr.C hot rolled plate 180mm thick is developed and produced by Steel Plant. The impact of SA302Gr.C steel plate is -20℃. 

A302Gr.C plate delivery condition: hot rolled, normalized, normalized + stress relieved.

A302 Gr.C alloy steel plate heat treatment process

When the thickness of A302Gr.C is less than 50mm, hot rolling, normalizing, normalizing + stress relief treatment can be selected. When the A302Gr.C plate thickness is greater than 50mm, the delivery state is normalized. When the A302Gr.C plate with a thickness greater than or equal to 100mm is normalized, it can be accelerated by a blower or liquid quenching and then tempered in the temperature range of 1100-1300 ° F (595-705). Similar mechanical properties to fire.

A302Gr.C hot rolled plate application
A302Gr.C is widely used in petroleum, chemical, power station, boiler and other industries, and is used to manufacture reactors, heat exchangers, separators and other equipment and components.
