300 Series stainless steels are classified as austenitic, and are hardenable only by cold working methods. These grades of stainless have chromium (approx. 18 to 30%) and nickel (approx. 6 to 20%) as their major alloying additions. Type 304 is the most widely used alloy of all stainless steels. 300 Series Stainless steel alloys resist corrosion, maintain their strength at high temperatures and are easy to maintain.

Resistance

 

Stainless steel’s resistance to corrosion and staining, low maintenance and familiar lustre make it an ideal material for many applications.The alloy is used in cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment and as an automotive and construction material in large buildings etc. It also can be use in commercial kitchens and food processing plants, as it can be steam-cleaned and sterilized and does not need paint or other surface finishes.

 

Applications

 

Food preparation equipment, especially in chloride environments
Chemical processing, equipment  
Laboratory benches and equipment
Rubber, plastics, pulp & paper machinery
Pollution control equipment
Boat fittings, value and pump trim
Heat exchangers
Pharmaceutical and textile industries
Condensers, evaporators and tanks
