Application/End products
202 High Cold Work hardening rate, good formability Water tubings.Watch parts foot rule, industrial  Knives,   bus body accessories, utensils,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 & 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.
304L 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 sensitisation.Good corrosion and oxidation resistance. Heater elements,process plant,furnace parts and high temperature tubes.
409M Good corrosion and oxidation resistance. Auto mufflars,catalytic converters and trasformer cases.
410S Weldable and resistance to scaling.Good corrosion and heat resistance. Turbine blades.fasteners and fishing tackle.
420 Superior wearability excellent,corrosion resistanat and hardnable to 500 BHN. Surgical instruments,Knife blades and valve parts.
430 Superior corrosion resistance and formable. Automobile trim and foof processing plants.
