X10CrWMoVNb9.2 is Among wrought stainless steels, the composition of EN 1.4901 stainless steel is notable for including zirconium (Zr) and boron (B). Zirconium is used to improve ductility and oxidation resistance. Boron is used to improve hardenability. It has a substantial effect when added in even tiny amounts. It is an improved version of the P91 / T91 / F91 material with a 2% addition of Tungsten, a slightly increased amount of Chromium, and a reduced content of Molybdenum, characterized by a creep resistance at temperatures of up to 600C higher by about 1/3. The material has even higher corrosion resistance and weldability. It is used at the highest operating temperatures up to 650C.Grade 91/92 - Steel used for production of boiler components with supercritical and ultra-critical parameters - jackets, connectors for steam superheater outlet chambers, superheated steam superheaters,X10CrWMoVNb9.2 forging turbine shaft parts, X10CrWMoVNb9-2 forging steel chambers and pipelines for fresh and superheated steam, superheater coils, steam collectors, outlet collectors, fittings and sleeves for the installation of boilers, connectors, pipelines of modern power units operating at temperatures of approximately 550-640C and steam pressures of approx. 18-30 MPa.
