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
