431 stainless steel is a martensitic stainless steel that is AOD melted. This alloy offers the best corrosion resistance of the conventional martensitic stainless grades. This grade is often used in the aerospace industry as fittings and boltings requiring high yield strength. Stainless 431 also has the best corrosion resistance to marine atmospheres, also resists attack by many petroleum products and organic materials, and several acidic environments.
Type 403 stainless is a corrosion and heat resistant 12% Cr martensitic alloy, very similar to stainless type 410, with the exception of a slightly lower maximum silicon content and a slightly lower maximum chromium content. Good levels of strength, toughness and ductility may be obtained with this alloy.
Stainless steel 310 is a medium carbon austenitic stainless steel, for high temperature applications such as furnace parts and heat treatment equipment. It is used at temperatures up to 1150°C in continuous service, and 1035°C in intermittent service. Its high chromium and nickel contents provide comparable corrosion resistance, superior resistance to oxidation and the retention of a larger […]
303 Stainless machines well and cuts clean and maintains it resistance to corrosion in temperatures up to 1500 degrees F. Good applications include repeat machining, fittings and fasteners.
