General :
Cr-Ni austenitic stainless steel. AISI302'den has better corrosion resistance . High ductility, excellent drawing , forming and spinning properties. Essentially nonmanyetiktir , but slightly magnetism occurs when cold worked . Thanks to a low carbon content less carbide precipitation during welding heat affected zones and has a lower sensitivity to intergranular corrosion .
Applications : blowers , chemical equipment , coal hopper linings, cooking equipment , cooling coils , cryogenic vessels, dairy equipment , evaporators , flatware utensils , feedwater pipe, flexible metal hose, food processing equipment , hospital surgical instruments, hypodermic needles, sink , marine equipment and fasteners, nuclear vessels , oil well filters , refrigeration equipment , paper industry, pots and pans , pressure vessels , plumbing , valves , shipping drums, spinning , still tubes, textile dyeing equipment, pipe .
Corrosion resistance: based on the most acidic and salt water oxidation .
