EN 1.4935 stainless steel is a martensitic stainless steel formulated for primary forming into wrought products. 1.4935 is the EN numeric designation for this material. X20CrMoWV12-1 is the EN chemical designation. X20CrMoWV12 is mainly used in making valve.
1.4935 Creep resistant steel used for thermal engine components in power plants, mainly turbine blades, but fasteners as well. Hardenable. Max temperature for continous operating is 580 °C.
Chrome-nickel steel with an austenitic structure with carbides. Alloying additions of molybdenum, vanadium and tungsten increase the melting temperature, thus having a positive effect on creep resistance.
we can produce this kind of super stainless steel which has chemical component of W ni and mo.
