Stainless Steel
TYPES OF
STAINLESS STEEL
AISI 201
It is an austenitic- Cr-Ni-Mn stainless steel that was developed to conserve nickel. This steel serves as a satisfactory alternate for AISI 301 with few exceptions, fabrication and corrosion resistance of the two grades are similar. It resists corrosion attach over relatively long period of exposure in both industrial and marine atmospheres. Uses include railroad, rapid transit, truck trailers, automotive trim, window frames and doors.
AISI 202
It is an austenitic- Cr-Ni-Mn stainless steel that was developed to conserve nickel. This steel an alternate type for type 302, was designed for applications where good forming characteristics are important. It resists corrosion in moderate corrosive environments, most organic and strongly oxiding acids, industrial and marine atmospheres. Uses include kitchen utensils such as pots, pans, washing machine tubs, door hardware, dairy equipment and architectural firm
AISI 301
It is an austenitic, Cr-Ni steel which can attain high tensile strength and ductility through moderate or severe cold working. This grade is often used in the cold rolled or cold drawn condition in the form of sheet, strip and wire. Uses include automobile wheel covers, transportation equipment, aircraft and missile structures, roof drainage products, kitchen utensils, storm door frames and tableware.
AISI 304
It is an austenitic, Cr-Ni stainless steel characterized by comparatively low carbon content and higher chromium and nickel contents than those of AISI 301 and 302. Uses include valves and accessories for chemical handling equipment, dairy equipment, spindles, nuts, bolts.
AISI 304L
It is very low carbon, austenitic, Cr-Ni steel. It is recommended for use in parts that are fabricated by brazing or welding and cannot be subsequently annealed. Applications include architectural trim, beer barrels, brewing equipment, chemical handling equipment, household appliances, textile drying equipment, dairy equipment, winery tanks etc.
AISI 310
It is an austenitic, Cr-Ni steels with high strength and excellent corrosion resistance. It is used in applications which involve sulphur bearing gases at elevate temperatures. This grade can be satisfactorily welded and brazed by the common methods. Uses include welding rod furnace parts, oil refining equipment, heat exchangers, oil burner parts, chemical plant equipment, jet engine parts, tube hangers etc.
AISI 316L
It is a very low carbon, austenitic – Cr- Ni stainless steel. This grade has general corrosion resistance similar to type 316, but super resistance to intergranular corrosion following welding or stress relieving. Applications include pulp handling, equipment for producing photographic chemicals, inks, rayon, rubber, textile bleaches, dyestuff, high temperature equipment.
AISI 306
It is molybdenum bearing- Cr-Ni- stainless steel and heat resistant steel. This grade has superior corrosion resistance over other CrNi steel when exposed to many types of chemical corrodents, as well as marine atmospheres. In addition, type 316 offers high creep, stress-torupture tensile strengths other than any other stainless steel. Uses include food processing equipment, textile dyeing equipment, nuclear fuel cladding and heat exchangers, oil refining equipment, household appliances etc
AISI 410
It is basic, harden able, martensitic, stainless alloy. It can be heat treated to a wide range of mechanical properties. Applications of AISI 410 include steam turbine bucket, blades, bucket covers, gas turbine compressor blades, nuclear reactor control rod mechanisms, valves, fasteners, petrochemical equipment, machine parts etc.
AISI 416
It is corrosion resistant chromium steels with added elements to improve machining and non-seizing characteristics. These grades are the most readily machinable of all stainless steel and are suitable for use in automatic screw machines. Applications include nongelling, non-seizing, corrosion-resistant parts machined on automatic screw machines such as screw, bolts, nuts and studs, rivets, automobile trim, valve parts,hardware etc..
AISI 420
It is high- carbon member or the hardenable (martensitic), 12% chromium family of stainless steels. The higher content provides higher heat-treated hardness than is characterized of type 410. Uses include cutlery, hand tools, dental and surgical instruments, valve trim and parts, shafts and plastic mold steels etc
