    General Properties

    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.

    Corrosion Resistance

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

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

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

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

     

    Machinability

    Slow speeds and high feeds will overcome this alloy’s tendency to work-harden

    Due to gummy chips, it is recommended that chip breakers are used on all tooling

     

    Weldability

    Can best be welded by resistance or shielded fusion methods

    Post weld annealing dissolves the chromium carbide and is recommended for maximum resistance to intergranular attack

     

    Hot Working

    Uniform heating to 2100oF will allow this allow to be forged, upset and headed successfully

    Do not work below 1700oF

     

    Cold Working

    Will dramatically increase the hardness of this material; however, it is quite ductile and may readily be drawn, spun and upset

    Causes alloy 302 to become magnetic

    Post-fabrication annealing is necessary to retain maximum corrosion resistance and a non-magnetic condition
