Effect of grain size on yield strength ratio of automotive industry used steel S355MC

Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often

Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate automotive industry used steel S355MC has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the automotive industry used steel S355MC 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 automotive industry used steel S355MC strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
