1Cr11Ni2W2MoV Martensitic Stainless Steel Bars and plates
It is a chromium-nickel-tungsten-molybdenum-vanadium martensitic heat-resistant steel with good toughness and oxidation resistance. It offers favorable corrosion resistance in fresh water and moist air, and features high high-temperature strength, maintaining stable mechanical properties in the temperature range of 550°C to 600°C. Its creep strength at high temperatures is prominent, and excellent comprehensive mechanical properties can be obtained through appropriate heat treatment.
Applications of 1Cr11Ni2W2MoV
The application scope of this material is mainly concentrated in aerospace, steam turbine manufacturing and other fields. It is commonly used to manufacture components subjected to high-temperature loads such as blades and disks. In marine power systems, it can be used to manufacture certain high-temperature components of gas turbines. Meanwhile, in high-temperature pumps, valves and other equipment in the petrochemical industry, it can also meet the requirements of components for heat resistance and mechanical properties.
