302 (UNS S30200) Stainless Steel

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


Standards:

  • ASTM/ASME: UNS S30200

  • EURONORM: FeMi35Cr20Cu4Mo2

  • DIN: 2.4660


Corrosion Resistance

  • Provides useful resistance to corrosion on a wide range of moderately oxidizing to moderately reducing environments

  • The 18 -19% of chromium which this alloy contains provides resistance to oxidizing environments such as dilute nitric acid.

  • Resistant to moderately aggressive organic acids such as acetic, and reducing acids such as phosphoric.

  • The 9-11% of nickel contained in this alloy provides resistance to moderately reducing environments.
