Q420B material is a low-alloy high-strength structural steel. Q690E carbon steel plate sheet, Q420 is not high-strength steel, it is still low-carbon steel. Its tensile strength has been improved a bit. The tensile strength of Q235 steel is 235MPa, and the tensile strength of Q420B steel is 420MPa. Q420B low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good Cold forming performance and welding performance; has good corrosion resistance and certain wear resistance.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the Q690E carbon steel plate 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 Q690E carbon steel plate sheet strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
