Stainless Steel has excellent forming and welding characteristics. It has very good drawability; its combination of low yield strength and high elongation permits successful forming of complex shapes. It offers excellent resistance to a wide range of atmospheric, chemical, textile and petroleum exposures.

- Does not stain, corrode or rust as easily as ordinary steel (it stains less, but is not stain proof)
Mild Steel – Mild steel is the most common form of steel as its price is relatively low. It is neither extremely brittle nor ductile, and has a low tensile strength. It becomes malleable when heated and therefore can be forged. Mild steels surface hardness can be increased through carburizing. Mild steel will rust.
