ASTM A 240/A 240M – 09b/ ASTM A959-2009 430 stainless steel
ASTM A240/A240M 430 is an martensitic stainless steel at american standard. It has several states, and under different states, dirt and corrosion resistance are not the same.ASTM A240/A240M 430 ferritic stainless steel, decorative, such as for automotive accessories. Good moldability , but poor temperature resistance and corrosion resistance.
ASTM A240/A240M 430 is used in a variety of interior and exterior trim applications where economy plus corrosion resistance is more important than high strength.Typical applications are sinks, sink rims, appliance trim, counter tops, dish washers, range hoods, and flatware.Other commercial applications include architectural uses, roofing, siding, and restaurant equipment.
