Description of material
VAL2MV is a Chromium-Molybdenum-Nickel-Vanadium martensitic stainless steel designed to supply high mechanical, creep and high temperature resisting properties and a good corrosion resistance in mild environments.
Applications
Thanks to a special chemical composition and exact steel making process, this grade is widely used in the power generation industries and steam turbine blade production, as well as in other applications where high temperature and creep resistance is required, such as turbine discs, bolting, fasteners for high temperature environments, screws, pins and clamp rings, parts for petrochemical plants, gas turbine compressor components, pump parts and valve components.
