Description of material
VAL2MCV is a Chromium –Molybdenum –Niobium-Vanadium martensitic stainless steel designed to supply high mechanical and creep resisting properties, together with high toughness due to its Nb addition is able to promote fine grain and a good corrosion resistance in mild environments. VAL2MCV/1 has slight differences of chemical composition but offers substantially the same performance.
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 blades production, as well as in other applications where high temperature resistance is required, such as turbine discs, bolting, fasteners for high temperature environments, screws, pins and clamp rings, parts of petrochemical plants, gas turbine compressor components, pump parts and valve components.
