- S 31008
- 310s
A Multi-Purpose Austenitic Heat Resistant Stainless Steel with Oxidation Resistance Under Mildly Cyclic Conditions to 2010°F (1100°C).
Because of its high chromium and moderate nickel content, Alloy 310 is resistant to sulfidation and can also be used in moderately carburizing atmospheres. Application-power plants, petrochemical industrie, furnace engineering.
