| SS-303 | Stainless Steel | Fe, Cr, Ni, S, Si | 55,000 | 42,000 | 5 | 6.4-6.6 | HRB 63-68 | Austenitic machining grade, preferred for parts requiring extensive machining, non-magnetic high strength and hardness. Good corrosion resistance | MPIF:
SS-303N2-35 ASTM: B 783-90 |
| SS-304 | Stainless Steel | Fe, Cr, Ni, Si | 57,000 | 40,000 | 10 | 6.4-6.6 | HRB 63-68 | General purpose austenitic grade, has good strength and corrosion resistance. Non-magnetic and non-machinable. Weak magnetic property. | MPIF:
SS-304N2-33 ASTM: B 783-90 |
| SS-316 | Stainless Steel |
Fe, Cr, Ni, Mo, Si | 60,000 | 39,000 | 10 | 6.4-6.6 | HRB 63-70 | Corrosion resistance is better than SS-303. First choice for general purpose applications. Non-magnetic. |
