CHARACTERISTICS OF STAINLESS STEEL ALLOYS
303
(NOT FOR SHEET METAL) For use in automatic machining applications (screws). Corrosion resistant to atmospheric exposures, sterilizing solutions, most organic and many inorganic chemicals; most dyes, nitric acid and foods.
304
The most widely used of the stainless steel and heat resisting steels. Offers good corrosion resistance to many chemical corrodents, as well as industrial atmospheres. Has very good formability and can be readily welded by all common methods. ASTM AS240 Cold rolled, annealed and pickled. Finishes: 2B, #3 and #4.
316
Better corrosion and pitting resistance, as well as higher strength at elevated temperatures than T304. Used for pumps, valves, textile and chemical equipment, pulp and paper, and marine applications. ASTM 240 Cold rolled, annealed and pickled. Finishes 2B, #3 and #4.
