S30815/253MA Duplex Stainless Steel Description
S30815/253ma stainless steel is a nickel-resistant heat-resistant austenitic stainless steel designed for applications requiring high creep strength and good corrosion resistance. The use of temperature range of 850 ~ 1100 temper.
1.compared with 310S, 1Cr20Ni14Si2, the performance is more superior, section Ni, cheap.
2.900 temper when there is a high strength. In the air, non-pressure conditions can be used to 1150 temper, with excellent resistance to high temperature oxidation.
3.the short-term tensile strength at each temperature than the usual stainless steel (such as 304,310 S) strength higher than 20%.
4.with high temperature long-term performance (creep performance, lasting performance).
In addition to alloying elements such as chromium and nickel, S31805 stainless steel also contains a small amount of rare earth metals (Rare Earth Metals, REM), which significantly improved its antioxidant capacity. Nitrogen is added to improve creep properties and make this steel complete austenite. Although the chromium and nickel content is relatively low, but this stainless steel in many cases with high alloying alloy steel and nickel-based alloy the same high-temperature characteristics
