N70MFV-VI, ЭП814А-VI round, wire, tube, sheet, strip

The basis of the material N70MFV-VI is a Nickel, in this regard, such materials (also known as ЭП814А-VI) acquires the whole complex of useful properties, which are widely applied in many areas of modern production. The working quality of the alloy is fully determined by its chemical composition, both qualitative and quantitative terms. Additional alloying components such as molybdenum, titanium, vanadium, tungsten and some other increase the heat resistance and other useful properties of the Nickel material.
