Correct welding method for A537 class 1 pressure vessel steel sheet

EN10083-3 27MnCrB5-2 steel plates usually need quenching and tempering are special application. Up to now, EN10083-3 27MnCrB5-2 steel plates are mainly applied in airplane, guided missile, weapons, railway, bridges, ships, vehicles, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on fields.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the A537 class 1 pressure vessel steel sheet 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 A537 class 1 pressure vessel steel sheet strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
