STAINLESS STEEL OVERVIEW: ALLOY CLASSIFICATIONS
200 Series Austenitic Alloys: 201, 202, 203, 204 & 205
Chromium-nickel-manganese alloy with high strength in the annealed . Non-magnetic, not heat treatable and has excellent formability for several forming
applications.
Typical use: washing machine tubs, structural applications.
300 Series Austenitic Alloys: 301, 302, 303, 304, 305, 308, 309, 310, 314, 316,
317, 321, 330, 347, 384
Chromium-nickel alloy can develop high strength by cold working. Non-magnetic, not heat treatable and has good formability. Additions of molybdenum can increase the corrosion resistance.
Typical use: Food equipment, chemical equipment, architectural applications
400 Series Ferritic Alloys: 405, 409, 429, 430, 434, 436, 442, 446
Straight chromium alloy, magnetic, but not heat treatable.
Typical use: Automotive trim, cooking utensils
400 Series Martensitic Alloys: 403, 410, 414, 416, 420, 422, 431, 440
Straight chromium alloy, magnetic, but can be hardened by heat treatment.
Typical use: Fasteners, pump shafts, turbine blades
Precipitation Hardening Alloys: 13-8, 15-5, 15-7, 17-4, 17-7
Chromium-nickel, martensitic or austenitic. Develop strength by precititation hardening reaction due to heat treatment.
Typical use: valves, gears, petro-chemical equipment

Typical use: valves, gears, petro-chemical equipment
Duplex Alloys: 329, 2205, 2304, 2507, 3RE60
Chromiun-nickel-molybdenum. More resistant to stress corrosion cracking than
austenitic, yet tougher than fully ferritic alloys.
Typical use: pipelines, pressure shafting
