Stainless Steel Strip Products

Austenitic

301

A chromium-nickel stainless steel that provides high strength and good ductility with chromium and nickel contents lowered to increase the work- hardening range. This permits higher tensile strengths to be achieved by rolling with a lower loss of ductility. When this grade is cold worked it becomes more magnetic than other austenitic stainless steels.

Typical uses include aircraft structural parts, diaphragms, utensils, automotive trim, and conveyor belts.

302, 304, 304L

Types 302, 304 and 304L are variations of the basic 18-8 grade with variations of nickel, chromium and carbon content. These grades are weakly magnetic when cold rolled. Lower carbon 304L minimizes chromium carbide precipitation and its susceptibility to inter granular corrosion.

These grades are the most used austenitic stainless steel grades and find applications in a great variety of applications.

305

A 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 under most conditions.

Typical uses include appliances, kitchen utensils, tank covers and other deep drawn parts.

309, 309s

Types 309 and 309s are austenitic chromium- nickel stainless steels that provide excellent corrosion resistance and heat resistance plus good strength at room and elevated temperatures.

Type 309s is identical to Type 309 except for a lower carbon content that minimizes carbide precipitation.

They become slightly magnetic when cold worked.

Typical uses include furnace parts, heating elements, aircraft and jet engine parts, heat exchangers, sulfite liquor handling equipment, boiler baffles, refinery and chemical processing equipment, and auto exhaust parts.

316

A chromium nickel stainless steel containing molybdenum. This addition increases general corrosion resistance to pitting from chloride ion solutions, and provides increased strength at elevated temperatures. Properties are similar to those of Type 304 except that this alloy is somewhat stronger at elevated temperatures.

Corrosion resistance is improved, particularly against sulfuric, hydrochloric, acetic, formic, and tartaric acids; acid sulfates and alkaline chlorides.

316L

316L is an extra-low carbon version of Type 316 that minimizes carbide precipitation.

Typical uses include exhaust manifolds, furnace parts, heat exchangers, jet engine parts, pharmaceutical and photographic equipment, valve and pump trim, chemical equipment, digesters, tanks, evaporators, pulp, paper and textile processing equipment and parts exposed to marine atmospheres and tubing.

Martensitic

410

Type 410 provides good corrosion resistance plus high strength and hardness. It is magnetic in both the annealed and hardened conditions. A wide range of properties can be developed with different heat treatments. Applications requiring moderate corrosion resistance and high mechanical properties are ideal for this alloy.

Typical uses include flat springs, knives, kitchen utensils, and hand tools.

420

Type 420 provides corrosion resistance similar to Type 410 plus increased strength and hardness. It is magnetic in both the annealed and hardened conditions. Maximum corrosion resistance is attained in the fully hardened or fully hardened and stress relieved condition.

Typical uses include cutlery, surgical and dental instruments, scissors, tapes, and straight edges.

Ferritic

430

Type 430 is one of the most widely used of the "non-hardenable" ferritic stainless steels. It combines good corrosion resistance and heat and oxidation with good mechanical properties.

Typical product applications include automotive trim and molding, dishwashers, range hoods, steam iron bases, and flatware and restaurant equipments.

Nickels

200, 201

Nickel 200/201 has properties that are useful in industries such as chemical processing and electronics.

Nickel is resistant to various reducing chemicals and alkaline materials. Compared with nickel alloys and many other materials 200/201 nickel has high electrical and thermal conductivity. It also has a high Curie temperature and good magnetostrictive properties. Annealed nickel has a low hardness and good ductility and formability. Those attributes, combined with good weldability, make the metal attractive for many types of parts.

Low Carbon

1006

1006 is a carbon steel containing mainly carbon as the alloying element. It contains about 0.4% silicon and 1.2% manganese. Chromium, nickel, aluminium, copper and molybdenum are also present in small quantities in the carbon steels. The features of AISI 1006 carbon steel are mainly softness and ductility.

Typical uses include infrared counter measure flare substrate, electronic parts carrier, low ohm etched heating element and conductor grid elements.

1008

1008 is a standard grade Carbon Steel. This alloy is generally used for "commercial quality" cold rolled steel. It is an economical, general purpose steel grade offering moderate strength and toughness. As a standard grade, 1008 steel is used in many common, low-stress applications. Weldability and brazeability are excellent.

Typical uses include infrared counter measure flare substrate, electronic parts carrier, low ohm etched heating element and conductor grid elements.

1010

1010 is a plain carbon steel with a nominal 0.10% carbon content. It is a relatively low strength steel but it may be quenched and tempered for increased strength.

Typical uses include infrared counter measure flare substrate, electronic parts carrier, low ohm etched heating element and conductor grid elements.
