1Cr25Ni20Si2
0Cr18Ni11Nb is a corrosion-resistant steel with the same characteristics and uses as 0Cr18Ni10Ti steel. It is an austenitic stainless steel stabilized with Nb. It is resistant to high-temperature corrosion and oxidation within the temperature range of 400~900 ℃, and can be used for pipe fittings with working temperature below 850 ℃. 0Cr18Ni11Nb (GB/T 1220-1992) is equivalent to American ASTM347. Because of its good corrosion resistance and welding performance, it is widely used in petrochemical, synthetic fiber, food, paper and other industrial sectors. In thermal power plant and nuclear power industry, it is used for large boiler superheater, reheater, steam pipe, shaft and various welded structural parts. As Nb is less prone to burn than Ti, this steel is often used as welding material such as welding core and welding strip.
