We stock a wide range of stainless steel alloys as well as high performance duplex and superduplex alloys, special precipitation-hardening grades and a range of aerospace specification materials. Stainless steel derives its fundamental characteristic of corrosion resistance from an addition of chromium, which forms a passive surface layer on the steel when exposed to oxygen.

The five basic types of stainless steel are Austenitic, Ferritic, Martensitic, Precipitation Hardening and Duplex. These all feature varying levels of corrosion resistance, pitting resistance, strength, hardness and temperature resistance.

Some of the specialist grades stocked by Columbia Metals include alloys such as 310 heat resisting stainless steel, 17/4 PH & 660B precipitation hardening stainless steel and S31803, S32550, S32750, S32760 duplex and superduplex stainless steels. In addition, we also hold stocks of specialist aerospace stainless steels such as S80, S130 and S143.
