SAE1018 1020 steel S20C SS400 S235JR A36 Application
SS400 steel is a structural grade steel used in general construction applications such as buildings, bridges, and other structures. SS400 steel also used in automotive and agricultural equipment. SS400 steel also used in some applications that require high strength and corrosion resistance, such as fasteners and storage tanks.
What is mild steel?
Mild steel is a low carbon steel with a medium manganese content. Has good case hardening properties, fair machinability and is excellent for cold bending and forming operations. Readily welded and brazed. Suitable for shafting and for applications that do not require the greater strength of high carbon and alloy steels.
