Stainless Steel Grades Chart






3CR12 Ferritic Useful corrosion resistance, particularly in wet abrasion environments. Readily welded and formed. Tanks, flues, bins, chutes, rail wagons




Low nickel, high work hardening. Cookware, hose clamps
301 Austenitic Combination of strength and ductility to withstand severe forming methods. Corrosion resistance comparable to 302. Rail cars, automotive components
302 Austenitic Excellent corrosion resistance. High strength and hardness. Food and drink, sanitary, cryogenic and pressure applications
303 Austenitic Addition of sulfur or selenium gives it best machinability of all austenitic grades, but reduces corrosion resistance compared to 304. Nuts and bolts, aircraft fittings and gears, bushings






Slightly magnetic when cold worked. Excellent corrosion resistance but susceptible to pitting corrosion in warm chloride environments. Excellent toughness


Accounts for 50% of all stainless steel produced.

Architecture, kitchens, food processing




Resistant to oxidation. Heating, furnace parts





Austenitic Same mechanical and physical properties as 304 but more resistant to pitting corrosion, especially in warm chloride environments. Virtually non-magnetic. Marine architectural components, food processing, hot water systems
317L Austenitic Improved corrosion resistance over 316. 317L is a variation of 317 suitable for heavy-gauge welding. Pulp and paper machinery, ink and dying processes, acetic acid distillation
321 Austenitic Titanium-stabilized. Aircraft, heat exchangers (up to intermediate temperatures)
400 Ferritic Corrosion resistance comparable to 409, better surface finish Caskets, applications requiring better finish than 409
409, Aluminized 409 Ferritic Resists atmospheric and automotive exhaust gas corrosion. Aluminized version adds salt and cosmetic corrosion resistance. Auto exhaust systems, heat exchangers, furnace liners
410, 410H Martensitic Resists dry atmospheres, freshwater, mild alkalis and acids, steam, and hot gases. Must harden for best heat and corrosion resistance. 410H has better hardenability. Bolts, nuts, screws, pump parts and shafts, turbine parts, mine ladder rungs, cutlery, rulers, cold heading
420, 420HC Martensitic Good resistance in hardened condition to atmosphere. Higher-carbon grade. HC offers better hardenability. Cutlery, stainless steel hospital equipment, needle valves




The tolerance of CNC Machining For Stainless Steel Parts

+/- 0.025 mm
+/- 0.001 inch

Hole diameters (not reamed) +/- 0.025 mm
+/- 0.001 inch

Shaft diameters +/- 0.025 mm
+/- 0.001 inch

Part size limit 950 * 750 *650 mm
38.0 * 22.5 * 22.5 inch
