430 Stainless Steel

UNS S43000

By far the most popular of all straight-chromium stainless steels, Type 430 is the general-purpose alloy of the ferritic class. Referred to as “17 Chrome stainless,” this grade offers favorable resistance to mild atmospheric corrosion and oxidizing environments. Its resistance to corrosion can be enhanced and reflectivity improved with bright annealing.

Type 430 is known to have moderate ductility limited forming, bending and welding characteristics and can be drawn to a moderate degree. This alloy is highly magnetic, resistant to scaling at 1500°F and has better resistance to dry sulphur-bearing gases than the chromium-nickel stainless type.

Uses for Type 430 include automotive & appliance trim and accessories, builder’s hardware, display cases, fasteners, interior architectural trim and paneling, combustion chambers and chimney liners and sinks, drains and trays.
