A.I.S.I. U.N.S. | Characteristics | End-Use |
301 S30100 | Able to attain tempers from 1⁄4 through full hard, extra full hard by cold rolling. Withstands severe forming in annealed condition. | Kitchen sinks, Automotive wheel covers. Toaster springs, Seat belt buckles |
303 S30300 | Highest machinability rating among the 300 series. Forming and welding are not recommended. | Nuts and bolts, threaded rods, Fittings. |
304 S30400 | Excellent corrosion resistance and suitable for deep drawing applications when Nickel content is increased. Carbon content .08% max. | Food Industry, Chemical Industry, Deep drawing applications, Aesthetic application. |
304L S30403 | Same characteristics as 304 with a lower carbon content .03% max. Used when post weld annealing is impossible. The lower carbon content reduces carbide precipitation in the welded zone. | Large fabricated equipment. |
316 S31600 | Molybdenum bearing alloy with better overall corrosion resistance than 304 and higher creep strength at elevated temperatures. | Marine coastal environments, Pulp and paper industry, Chemical and petrochemical Industry |
316L S31603 | Same characteristics as 316 with a lower Carbon content .03 max. Good corros ion resistance in high temperature intermittent service. Used when post weld annealing is impossible. The lower carbon content reduces Carbide precipitation in the welded zone. | Large fabricated equipment. |
317L S31703 | Higher Molybdenum content than 316 for better corrosion resistance. Carbon content .03% max. | Corrosive environments. Chemical and petrochemical industries. |
309 S30900 309S S30908 | Heat resisting alloy with good corrosion resistance. High tensile and creep strengths as well as at elevated temperatures. 309S has a lower Carbon content.03 max. | Furnace parts, Baffles, Cement kiln chains. Exhaust manifold butterfly valves. |
310 S31000 310S S31008 | Improved characteristics over 309 and better scaling resistance in intermittent elevated temperatures. Grade 310 has a low co-efficient of expansion. | Furnace parts, Carburizing boxes, Heat exchangers, Oil burner parts. |
Finish | Definition | Application |
2B | Finished by heat treatment , picking or equipvalent cold rolling , followed by skin pass to obtain adequate luster surface | with bright and smooth surface ,easy for further grinding to obtain brighter surface ,suitable for medical instruments ,milk containers ,tableware |
BA | bright heat treatment after cold rolling | structual members .etc.kitchen utensil ,cutlery ,eleltric applicances ,medical instruments ,building decorations ,etc. |
NO.3/NO.4 | polished with No.150-240 abrasives | milky food processing equipment , medicalinstruments ,building decorations |
HL | finshed by polishing with abrasives of suitable grain size to obtain continuous streaks | building decorations ,such as elevators ,escalators ,door.etc |
8K | A mirror-like reflective surface ,which is obtained by polishing with successively finer abrasives and buffing extensively with all gritlines are removed | buliding entrances,bulkding column casting ,elevator's wall * doors ,counters,sculptures |
