253MA ( S30815 ) Nickel-efficient & Heat-resisting austenitic stainless steel

Property: S30815 is a heat-resistant austenitic stainless steel, for the needs of high creep strength and good corrosion resistance force applications. Its temperature range of 850 ~ 1100 ℃.

Application: In addition to the alloying elements chromium and nickel, the grades of stainless steel also contain small amounts of rare earth metals, thereby significantly improving their antioxidant capacity. Adding nitrogen to improve the creep properties of the steel and to become a fully austenitic. Although chromium and nickel content is relatively low, but the high temperature properties of stainless steel having a high alloyed steel and nickel-based alloys in many cases the same.

S30815 heat-resistant stainless steel is based on the Cr21-Ni11, by adding rare earth elements and 1400-2000ppm appropriate amount of N, to achieve the purpose of improving the high temperature properties of steel, compared with the common 310S (0Cr25Ni20), in the precious metals Ni, under the premise of a significant reduction in the content, performance can be improved, the market prospect is broad.

Application Range: S30815 device is widely used in sintering, blast furnace equipment, steel melting furnace and continuous casting equipment, steel rolling machine (oven), heat treatment furnace and accessories, mineral equipment and cement production equipment. S30815 steel can be used to pressure situations and working temperature up to 900 ℃ 1150 ℃ non-pressure high-temperature components.
