Corrosion Resistance
310 / 310S stainless steel (1.4845) has excellent corrosion resistance at normal temperatures but is primarily designed to perform at high temperatures. In these high-temperature environments, 310 / 310S (1.4845) maintains very good corrosion resistance and also has exceptional resistance to; oxidizing and carburizing atmospheres and other forms of hot corrosion, up to a maximum dry air service temperature of 1100ºC. Other corrosive compounds such as water and sulphur compounds will significantly reduce the maximum service temperature.
