310 high temperature oxidation resistance
Stainless steel is made to have oxidation resistance by local oxidation of chromium, and a very stable oxide (Cr2O3 chromium oxide) can be formed during the local oxidation of chromium. As long as the chromium content of the metal is sufficient, a continuous layer of chrome oxide green can be formed on the metal surface to prevent the formation of other oxides and protect the metal. The oxidation resistance of austenitic stainless steel can be estimated by the chromium content. The high temperature resistant alloy contains at least 20% by weight of chromium. Replacing the iron component with a nickel component also generally provides the properties of the alloy at elevated temperatures. 309/309S, 310/310S are high-alloy materials and therefore have quite good oxidation resistance.
310 heat treatment / annealing
The main reason for annealing these alloys is to produce a recrystallized fine structure that achieves uniform grain size and decomposes harmful chromium carbide precipitates.
