Stainless Steel Alloys

Type 201

Type 201 is an austenitic chromium-nickel-manganese stainless steel that was developed originally to conserve nickel. It provides properties similar to Type 301 and can be used in most applications for Type 301. This alloy is non-magnetic in the annealed condition, but becomes magnetic when cold worked. The rate of work hardening is similar to Type 301, although Type 201 develops somewhat higher yield strength while retaining equal ductility when cold worked. Toughness at low temperatures is excellent. Typical uses include appliances, restaurant equipment, cooking utensils, sinks, automotive trim, architectural applications such as windows and doors, railway cars, trailers and hose clamps. 

Type 303

NOT FOR SHEETMETAL. For use in automatic machining applications (screws). Corrosion resistant to atmospheric exposures, sterilizing solutions, most organic and many inorganic chemicals: most dyes, nitric acid and foods.

Type 304

The most widely used of the stainless steel and heat resisting steels. Offers good corrosion resistance to many chemical corrodents as well as industrial atmospheres. Has very good formability and can be annealed and picked. Finishes: 2B, #3, and #4

Type 316

Better corrosion and pitting resistance as well as higher strength at elevated temperatures than Type 304. Used for pumps, valves, textile and chemical equipment, pulp & paper, and marine applications. ASTM A240 Cold rolled, annealed and picked. Finishes: 2B, #3, and #4

Type 410

Heat-treatable stainless used widely where corrosion resistance is not severe (air, fresh water, some chemicals). Frequently used in cutlery. This series is martensitic (magnetic). ASTM A240 Hot rolled, annealed and picked. Finishes: Dull

Ti-6Al-4V or Ti 6-4

Is the most commonly used alloy. It has a chemical composition of 6% aluminium, 4% vanadium, 0.25% (maximum) iron, 0.2% (maximum) oxygen, and the remainder titanium. It is significantly stronger than commercially pure titanium while having the same stiffness and thermal properties (excluding thermal conductivity, which is about 60% lower in Grade 5 Ti than in CP Ti). Among its many advantages, it is heat treatable. This grade is an excellent combination of strength, corrosion resistance, weld and fabricability.

Hot Rolled Steel - A36

Hot rolling involves the production of sheet metal from billets by passing the steel through rollers while above its recrystallization temperature to desired physical dimensions. Multiple passes through the rollers may be necessary to produce the final dimensions.
