What is the plasticity of S420N material vs a573 gr.65 steel sheet

ASTM A285 is an ordinary carbon steel used for fusion welding of pressure vessel equipment, such as S420N material vs a573 gr.65 steel boilers, storage tanks, heat exchangers, etc. The tensile strength of the three steel grades (Grade A, Grade B, and Grade C) ranges from 310-515Mpa, and ASTM A285 steel plates are usually delivered in the rolled state. According to user requirements, S420N material vs a573 gr.65 steel is produced by processes such as compaction, semi-compaction, edge sealing and boiling water.

Grades S420N material vs a573 gr.65 steel, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the S420N material vs a573 gr.65 steel metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between S420N material vs a573 gr.65 steel strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
