shanghai katalor can supply Alloy 302 (UNS S30200) in sheet, sheet coil, plate, round bar, processed flat bar and tubular products.

General Properties

Alloy 302 is a variations of the 18% chromium / 8% nickel austenitic alloy, which is the most familiar and the most frequently used in the stainless steel family. Alloy 302 is a slightly higher carbon version of 304, often found in strip and wire forms. It is a tough, ductile grade that demonstrates comparable corrosion resistance, is non-magnetic, and is not hardenable by heat treatment. Alloy 302 is usually used in its annealed condition and has a high ease of fabrication and formability.

Specifications: UNS S30200

Applications:

Although many applications have shifted to 304 and 304L due to advances in melting technology, availability, and cost, Alloy 302 is still used in a variety of industries. Some examples include:

Stamping
Spinning
Wire forming
Formed into all types of washers, springs, screens, and cables
Food and beverage industry
Pressure containing applications
Sanitary or cryogenic applications

Some examples of products that are partially or completely constructed of 302 include:

Blenders
Counters
Dish racks
Dishwashers
Refrigerators
Washing machines
