Mild Steel EN16
Materials Mild Steel EN16 (605M36)
Description
EN16 is a high tensile, low alloy steel known for its excellent ductility, shock resistance, and good machinability. It offers greater strength and toughness than EN8, making it suitable for components under dynamic loading. Often used in the automotive, aerospace, and general engineering sectors, EN16 can be heat-treated to improve mechanical properties while maintaining good machinability.
