Stainless Steels

AISI Type 17-7 Stainless Steel

AISI Type 17-7 is a precipitation hardening stainless steel that provides high strength and hardness, excellent fatigue properties, good corrosion resistance, good formability, and mini- mum distortion upon heat treatment. The alloy provides valuable property combinations particularly well suited for aerospace applications. This special alloy also provides benefits for other applications requiring high strength and good corrosion resistance, as well as excellent properties for flat springs at temperatures up to 600°F (316°C).

AISI Type 204Cu Stainless Steel

AISI 204Cu Stainless Steel can be used both in fully annealed and in fully or partially cold worked conditions. The alloy has good toughness and ductility and therefore, is readily formed to deep drawn components. 204Cu responds well to bending and drawing, similar to AISI 304, but moderately higher force is required. Compared with Type 304 and 430, 204Cu has better abrasion, scratch dent and galling resistance.

AISI Type 302 Stainless Steel

AISI type 302 stainless steel wire is used for applications where good corrosion resistance is important, but hardness is not. This form of wire offers good resistance to atmospheric corrosion, dyes, food, environmental sterilizing solutions and many organic and inorganic materials.

AISI Type 302HQ Stainless Steel

AISI type 302HQ stainless steel wire is used for applications where good corrosion resistance is important, but hardness is not. This form of wire offers good resistance to atmospheric corrosion and is commonly used for the manufacturing of self-tapping screws, roofing bolts, machine screws, bolts, set screws, and blind rivets.

AISI Type 303 Stainless Steel

AISI type 3030 stainless steel wire is the most readily machinable of all the austenitic grades of stainless steel. The machinable nature is due to the presence of sulphur in the steels composition. The sulphur improves machining, though it also causes a decrease in the corrosion resistance and a slight lowering of the toughness. The corrosion resistance of 303 is lower than that of 304. Type 303 is most commonly used in nuts, bolts, screws, gears, aircraft fittings, and bushings.

AISI Type 304 Stainless Steel

AISI type 304 stainless steel wire is used where good corrosion resistance is important, but hardness is not. They offer good resistance to atmospheric corrosion, dyes, food environments, sterilizing solutions and many organic and inorganic materials. Type 304 wire is commonly used in medical applications, animal feeders, trigger sprayers, finger pumps and food processing.

AISI Type 304L Stainless Steel

AISI Type 304L is a lower carbon variant of Grade 304 – the steel can be welded without the resulting issue of carbon precipitation. As a result, Type 304L stainless steel is a sought after material for use in severely corrosive conditions. This steel grade is found in a variety of commercial sectors, particularly in the chemical industry.

AISI Type 305 Stainless Steel

AISI Type 305 is an austenitic chromium-nickel stainless steel that can be spun and deep drawn more easily due to an increased nickel content that decreases work hardening. It is nonmagnetic and cannot be hardened by heat treatment. Typical uses include appliances, kitchen utensils, tank covers and other deep drawn parts.

AISI Type 314 Stainless Steel

AISI Type 314 has better corrosion resistance than Type 302. High ductility, excellent drawing, forming, and spinning properties. Essentially non-magnetic, becomes slightly magnetic when cold worked. Low carbon content means less carbide precipitation in the heat-affected zone during welding and a lower susceptibility to intergranular corrosion. Common applications include chemical equipment, cooking equipment, cooling coils, evaporators, flexible metal hose, food processing equipment, hospital surgical equipment, hypodermic needles, marine equipment and fasteners, nuclear vessels, refrigeration equipment, sanitary fittings, and valves.

AISI Type 316 Stainless Steel

AISI type 316 stainless steel offers excellent corrosion resistance and resistance to sulphuric acid compounds. This austenitic steel includes 2-3% molybdenum. Type 316 is used in trigger sprayers, bearings, dispenser valves, body jewelry, lotion pumps, quick-disconnect couplings and aerospace applications. Type 316LVM is used in jewelry, human implant and other medical applications.

AISI Type 316L Stainless Steel

AISI type 316L stainless steel has a lower carbon content than 316 stainless, which gives it even higher corrosion resistance than the excellent resistance of type 316. Both types offer excellent resistance to sulphuric acid compounds. Type 316L stainless steel applications include Jewelry and medical uses.

AISI Type 410 Stainless Steel

AISI Type 410 stainless steel is a martensitic (high-strength iron/chromium). Type 410 is wear-resistant, but less corrosion-resistant than many other types.

AISI Type 416 Stainless Steel

AISI Type 416 stainless steel wire is easily  machinable due to additional sulfur.

AISI Type 420 Stainless Steel

AISI type 420 stainless steel wire has fair-to-good corrosion resistance and good material strength. Type 420 resists corrosion from alcohol, ammonia, food environments, fresh water, many petroleum products and organic materials and some mild acid environments. They are found in bearings, valves, lighters and writing instruments.

AISI Type 430 Stainless Steel

AISI type 430 stainless steel wire provides fair to-good corrosion resistance. Type 430 resists corrosion from fresh water, steam, food environments, dairy products, nitric acid and many petroleum products and organic material. Applications include balls in cosmetics agitators such as nail polish and eyeliners, as dispenser pump balls and valve balls.

AISI Type NIT50 Stainless Steel

AISI Nitronic 50 stainless steel is an austenitic stainless steel offering a blend of strength and superior corrosion resistance. Unlike many stainless steels, Nitronic 50 does not become magnetic when cold-worked. AISI Nitronic 50 wire applications include ball bearings in dispenser valves, finger pumps and spray pumps.
