Characteristics and Applications

Stainless Steel Grades AISI

Main Characteristics Typical Application / End products

202

High Cold Work hardening rate, good formability. Water Tubings, watch parts, foot rule, Industrial Knives, bus body accessories, Kitchen appliances, Kerosene and Gas Stove parts.
301 Attains high strength by being cold worked, while retaining good ductility. Used in cold worked condition for springs and wear plates.
304 Better welding characteristics with good formability and general corrosion resistance. Watch parts, engine gaskets, flexible hoses, foot rule, door, hinges, capillary tubings and sinks.
304 L Low carbon content, weldable and resistance to sensitisation. Good corrosion and oxidation resistance. Hypodermic needles and capillary tubings.
316 Superior corrosion resistance to sea water and many chemicals and weldable. Engine gaskets, flexible hoses, process plant and paper industry equipment.
316 L Low carbon content highly corrosion resistant, weldable and resistant to sensitisation. Process plant parts particularly in thick sections.
321 Weldable and resistant to sensatitisation. Good corrosion and oxidation resistance. Heater elements, process plant, furnace parts and high temperature tubes.
409 M Good corrosion and oxidation resistance Auto mufflars, catalytic converters and transformer cases.
410 S Weldable and resistance to scaling. Good corrosion and heat resistance. Turbine blades, fasteners and finishing tackle.
420 Superior wearability, excellent corrosion resistace and hardenable to 500 BHN. Surgical instruments, knife blades and valve parts.
430 Superior corrosion resistance and formable. Automobile trim and food processing plants.
J4 (1%Ni) High cold work hardening rate, normal formability Welded tubes and fabrication
JT High cold work hardening rate, normal formability Welded tubes and fabrication
