Stainless Steel Description








201
Chromium nickel manganese steel was developed as a satisfactory alternate for Type 301 for many applications.
301
Chromium nickel steel capable of attaining high tensile strength and ductility by moderate or severe cold working.
302
General purpose chromium nicke stainless steel. Its corrosion resistance is superior to that of Type 301. It can be cold worked to high tensile strengths but with slightly lower ductility than Type 301.
304
Low carbon chromium nickel stainless and heat resisting steel somewhat superior to Type 302 in corrosion resistance.
304L
Very low carbon chromium nickel steel with general corrosion resistance similar to Type 304 but with superior resistance to intergranular corrosion following welding or stress relieving. It is recommended for use in parts which are fabricated by welding and which cannot be subsequently annealed.
305
A high corrosion-resistant alloy with low rate of work hardening, designed for extra deep drawing and spinning.
309
High corrosion-resistant, chromium nickel grade with carbon limited to .08 to reduce carbon precipitation during welding.
310
Similar to 309 with higher resistance to corrosion and oxidation at elevated temperatures.
316
Chromium nickel stainless and heat resisting steel with superior corrosion resistance to other chromium nickel steels when exposed to many types of chemical corrodents; superior creep strength at elevated temperatures.




316L
Low carbon chromium nickel stainless steel with general corrosion resistance similar to Type 316 but with superior resistance to intergranular corrosion following welding or relieving. It is recommended for use in parts which are fabricated by welding and cannot be subsequently annealed.
316TI
Ti stabalized version of 316 with resistance to sensitization. (The formation of grain boundary chromium carbides at evaluated temperatures.)
317L Similar to 316L but with additional molybdenum to improve corrosion resistance.
321
Chromium nickel steel containing titanium.Recommended for parts fabricated by welding which cannot be subsequently annealed. Also recommended for parts to be used at temperatures between 800°F and 1850°F.
347
Chromium nickel steel containing columbium and tantalum which is recommended for parts fabricated by welding which cannot be subsequently annealed. Also recommended for parts to be used at temperatures between 800°F and 1850°F.
410
General purpose corrosion and heat resisting chromium steel. Good corrosion resistance and fair machining properties. Can be treated to RC35/45.
420
Chromium steel capable of hardening to a maximum of approximately RC53/58.
430
General purpose grade, corrosion-resistant, straight chromium grade, non-heat-treatable.
430LI
Similar to straight 430 in corrosion and mechanical properties. The low interstitials provide improved transverse bending over straight 430.
434
Modification of Grade 430 designed for automotive trim and resistance to atmospheric corrosion.
440A
High carbon grade, high chromium, capable of being heat treated to a hardness range of RC51/62.
444
A low carbon, low nitrogen, ferritic that provides pitting and crevice corrosion resistance superior to most ferritic grades.
A2864
An iron, nickel chromium alloy designed for service up to 1300°F where high strength and corrosion resistance are required.
AM 3508
Similar to 17-7PH. alloy and PH15-7Mo. alloy, but with slightly higher elevated temperature capability.
CARPENTER
® 20 CB3, 10
A highly corrosion-resistant alloy used in the chemical industry for applications where corrosion resistance is extremely critical,superior to the general run of 300 type stainless.
PH15-7Mo®4
Similar to 17-7PH. alloy, but with molybdenum added for higher strength with heat treatment.
