When selecting steel the tests for corrosion resistance under temperature, under load in contact with technological media, under specific industrial production conditions are decisive.
CrN75MVY wire is characterized by:
-hardness - up to 321 MPa;
-Tensile strength - up to 590 MPa;
-Relative narrowing - up to 95;
-Relative elongation - within 6%.
Due to high performance qualities, this steel is widely used With the advent of similar materials of the new generation, it became possible to ensure long-term reliable operation of equipment under the most extreme conditions. The unique properties of the material due to its balanced composition and a special processing technology Thanks to the additives of tungsten, molybdenum, vanadium, cold-rolled stainless steel sheet CHN75VMY has high heat resistance, and heat resistance, so it can operate at temperatures up to 1000 ° C.
Application
The alloy of this brand is practically irreplaceable in industrial chemistry, transport engineering, aircraft industry, because of its excellent properties it is ideal for welded chemical equipment, as well as blades of gas turbines, fastening elements of engines
