Main Characteristic

 

Typical Application / End Use

201/202  High Cold Work hardening rate, good  Formability
 Water Tubings, watch parts, knives, bus  body  accessories, Kitchen wear, Kerosene  and Gas  Stove Parts.
 304  Better welding characteristics with good  formability and general corrosion resistance.  Watch parts, Engine Gaskets, Door, Hinges,  Capillary tubing.
 304 L  Low carbon content, weldable and resistance   to  sensitization. Good corrosion and oxidation  resistance.  Hypodermic needles and capillary
 316  Superior corrosion resistance to sea water and  many chemicals and weldable.  Engine gaskets, Flexible hoses, paper  industry Equipment.
 316 L  Low carbon content highly corrosion resistant  weldable and resistant to sensitization.  Process plant parts particularly in Heater  elements, Process plant, for high  temperature tubes.
