Stainless steel is a versatile material comprised of a steel alloy and a small percentage of chromium — the addition of chromium adds to the material’s corrosion resistance, a trait that earned stainless steel its name. Because stainless steel is also low-maintenance, oxidation resistant, and doesn’t affect other metals it comes in contact with, it is frequently used in a large array of applications, especially in piping and tubing manufacturing.

A.I.S.I. U.N.S. | Characteristics | End-Use |
301 S30100 | Able to attain tempers from 1⁄4 through fullhard, extra full hard by cold rolling.Withstands severe forming in annealedcondition. | Kitchen sinks, Automotive wheelcovers. Toaster springs, Seat beltbuckles |
303 S30300 | Highest machinability rating among the300 series. Forming and welding are notrecommended. | Nuts and bolts, threaded rods,Fittings. |
304 S30400 | Excellent corrosion resistance and suitablefor deep drawing applications when Nickelcontent is increased. Carbon content.08% max. | Food Industry, Chemical Industry,Deep drawing applications, Aestheticapplication. |
304L S30403 | Same characteristics as 304 with a lowercarbon content .03% max. Used whenpost weld annealing is impossible. Thelower carbon content reduces carbide precipitation in the welded zone. | Large fabricated equipment. |
316 S31600 | Molybdenum bearing alloy with betteroverall corrosion resistance than 304 and higher creep strength at elevated temperatures. | Marine coastal environments, Pulpand paper industry, Chemical andpetrochemical Industry |
316L S31603 | Same characteristics as 316 with a lower Carbon content .03 max. Good corrosion resistance in high temperature intermittentservice. Used when post weld annealing is impossible. The lower carbon contentreduces Carbide precipitation in the welded zone. | Large fabricated equipment. |
317L S31703 | Higher Molybdenum content than 316 forbetter corrosion resistance. Carbon content .03% max. | Corrosive environments. Chemicaland petrochemical industries. |
309 S30900 309S S30908 | Heat resisting alloy with good corrosionresistance. High tensile and creepstrengths as well as at elevated temperatures. 309S has a lower Carbon content.03 max. | Furnace parts, Baffles, Cement kilnchains. Exhaust manifold butterflyvalves. |
310 S31000 310S S31008 | Improved characteristics over 309 andbetter scaling resistance in intermittentelevated temperatures. Grade 310 has alow co-efficient of expansion. | Furnace parts, Carburizing boxes,Heat exchangers, Oil burner parts. |
