    310 Stainless Steel

    Type 310/310S Stainless Steel is covered by the following specifications:ASTM A 167, ASTM A240.

    Chemical Composition: 

    Element Type 310 Type 310S
    Carbon 0.25 max. 0.08 max.
    Manganese 2.00 max. 2.00 max.
    Sulfur 0.030 max. 0.030 max.
    Phosphorus 0.045 max. 0.045 max.
    Silicon 1.50 max. 1.50 max.
    Chromium 24.0 – 26.0 24.0 – 26.0
    Nickel 19.0 – 22.0 19.0 – 22.0

    Mechanical Properties:

    Type Yield Strength 0.2% offset (KSI) Tensile Strength (KSI) % Elongation (2" Gauge length) Hardness Rockwell
    310 30 min. 75 min. 40 min. HRB 95 max.
    310S 30 min. 75 min. 40 min. HRB 95 max.


    Fabrication:
    Commonly used in the heat treatment and process industries due to high temperature and corrosive environments
    Often fabricated into complex structures
    Roller-forms, stamps and draws readily
    Because 310 work hardens, severe forming operations should be followed by an anneal


    Weldability:
    Austenitic stainless steel is generally considered to be weldable
    Generally considered to have weldability equivalent to 304 and 304L
    Special consideration is needed to compensate for a higher coefficient of thermal expansion to avoid warping and distortion
