Overview
310 / 310S stainless steel (1.4845) is one of the most widely used grades of heat-resistant stainless steel, supplied to numerous industry sectors.
The key properties of 310 stainless steel are its high chromium and medium nickel content, providing excellent resistance to oxidation, sulfidation and other forms of hot corrosion. 310 / 310S stainless steel retains good strength when exposed to high temperatures and, like most austenitic grades, maintains its strength and toughness at sub-zero temperatures.
Overall, this grade is an excellent choice for various applications, ranging from furnace components to burner tips. 310 / 310S stainless steel has a maximum dry air service temperature of 1100°C.

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 stainless steel maintains very good corrosion resistance and offers exceptional resistance to oxidising and carburising atmospheres and other forms of hot corrosion, up to a maximum dry air service temperature of 1100°C.
Other corrosive compounds, such as water and sulphur compounds, will significantly reduce the maximum service temperature.
