Weldable fine-grained steel S420M plates are thermomechanically rolled structural steel materials with excellent welding performance. S420M steel plate is used in low-temperature structural parts, mechanical structures, building structures, bridges, ocean engineering and other fields. S420M material is suitable for heavy-duty parts of welded structures used in low-temperature conditions, such as bridges, sluices, storage tanks, water supply tanks, etc.
S420M plates have good tensile strength and processability, and can be used to manufacture some engineering equipment, mining equipment, etc.
S420M plate can adopt normalizing or hot-rolling heat treatment process, depending on the scope of use and application requirements. If the tensile and yield strength of the S420M steel plate is required, we can choose the normalizing heat treatment process.
