High temperature oxidation resistance for 310/310S material
310 310S stainless steel through the oxidation of chromium to the local oxidation resistance, in the local oxidation of chromium in the process, can form a very stable oxide (Cr2O3 chromium oxide). As long as the chromium content of the metal, the metal surface can form a continuous layer of chromium oxide green, to prevent the formation of other oxides, and to protect the metal. The oxidation resistance of austenitic stainless steel can be calculated by chromium content. High temperature resistant alloy chromium content of at least 20% (weight percent). The use of nickel as a substitute for iron can also provide the properties of alloys at elevated temperatures. 310/310S is a high alloy material, so it has good oxidation resistance.
Heat treatment / annealing for 310/310S material
The main reason for the annealing of these alloys is the formation of a recrystallized fine structure, uniform grain size, decomposition of harmful chromium carbide precipitates.
