ST37 Hot Rolled Mild Steel Coils

After proper heat treatment or cold drawing hardening, ST37 Hot Rolled Mild Steel Coil has high strength and hardness, high elastic limit and fatigue limit, and the cutting performance is acceptable, but the welding performance and cold plastic deformation ability are poor. Due to the high carbon content of ST37 Hot Rolled Mild Steel Coil, cracks are likely to occur during water quenching, so double-liquid quenching is often used, and oil quenching is mostly used for small-section parts.
