|EXTRA BRIGHT ANNEALED SOFT TEMPER 430 Stainless Strip Steel is the most popular of all the straight chrome stainless steels. Its principal use is for decorative purposes. Because of its excellent heat and corrosion resistant properties, its ductility and because it costs less than the chrome-nickel grades, this Type 430 Stainless Steel Strip is used in countless applications. These uses are primarily for stainless and decorative purposes including household appliances, metal molding, metal trim, cabinet hardware, hinges, drawn and formed parts and stampings.
|(17% straight chrome) Ferritic Stainless Steel Strip. This is the basic and most generally used straight chromium (Ferritic) Stainless Strip Steel. Because of its high chromium content, it is highly corrosion and heat resistant but somewhat less than Types 301, 302 and 304. It possesses good physical and mechanical characteristics but with ductility at about 75% of low carbon strip and inferior to that of the chrome-nickel grades. Like other straight chromium grades, Type 430 Annealed is subject to stretcher strains. Skin passing following annealing greatly reduces this possibility although this reduces ductility somewhat. Likewise a condition akin to stretcher strains may sometimes develop during deep drawing known as roping. Roping is characterized by the appearance of shallow ridges and valleys in the side walls and caused by excessive stretching. Type 430 is magnetic in all conditions, is not heat-treatable for hardening purposes and is weldable but its welds are not suitable in rigorous service. The tensile strength for SS 430 in the annealed condition is cataloged at 65,000 PSI minimum, its yield at 30,000 PSI minimum and elongation at 22%.
