Stainless Steel, Ferritic1.4003 (3CR12)

A utility ferritic stainless steel, often used in place of mild steel.

Type 1.4003 stainless steel was developed as an alternative material for construction where the mechanical properties, corrosion resistance and fabrication requirements of other materials such as mild steel, galvanised steel, aluminised steel, aluminium or pre-painted steels are unsuitable.

It offers the benefits of more highly alloyed stainless steels such as strength, corrosion and abrasion resistance, durability and low maintenance. In addition type 1.4003 Is weldable and formable allowing it to be fabricated using conventional techniques.
