310 Stainless Steel

310 stainless steel stockholders and suppliers. 310 is a heat resisting stainless steel grade available in bar plate and tube with delivery to the whole of the UK. It offers high resistance to oxidation scaling with high strength at elevated temperatures. 310 has much better creep strength at elevated temperatures than other austenitic stainless steel grades. Stainless 310 has good resistance to oxidation in continuous service up to approximately 1100°C.

310 offers excellent corrosion resistance and in many environments and has better corrosion resistant properties to austenitic stainless grade 304.

310 stainless steel is readily weldable with most welding procedures although oxyacetylene welding is not recommended due to possible carbon pick up in the weld area. As with welding of most austenitic stainless steel grades when filler metal is required, matching compositions are generally used. We recommend you contact your welding consumables supplier who should provide you full assistance and information on welding stainless steel.

Heat the 310 stainless slowly and uniformly throughout the section to 1100-1230°C. Re heat as necessary and avoid working below 1000°C. Rapid cooling is required to maximize corrosion resistance. Forgings will require annealing in order to obtain optimum corrosion resistance.

The oxidation resistance of a stainless steel is traditionally termed as the scaling temperature. This is the temperature at which the oxidation rate of the stainless steel becomes unacceptably high. The safe scaling temperature for continuous service of stainless 310 is 1100°C. In an oxidising and reducing sulphurous atmosphere the scaling temperature of 310 stainless is lowered.
