One of the most widely used "non-hardenable" stainless steels; magnetic in all conditions, good physical and mechanical characteristics, about three-quarters the ductility of low carbon strip and inferior to chrome-nickel grades; cost less than chromium-nickel stainless steels.
Applications: cabinet hardware, decorative appliance and automotive molding and trim, range hoods, restaurant equipment, drawn and formed parts and stampings.
Corrosion Resistance: Excellent resistance to citric and nitric acid, sulfur gases; slightly less corrosion and heat resistant than Types 301, 302, and 304.
Weldability: Poorer than Type 409; use common fusion and resistance techniques, but welds not suitable for rigorous service. Use AWS E/ER 308L or 430 weld filler.
Processing: Annealed 430 is susceptible to stretcher strains and roping. Skin passing after annealing reduces the likelihood of stretcher strains, but can also reduce the ductility somewhat.
