2Cr11NiMoNbVN Martensitic Stainless Steel Bars and plates
It is a martensitic heat-resistant stainless steel with high high-temperature strength and good oxidation resistance. It maintains good mechanical stability in the temperature range of 500°C to 600°C, while also offering certain corrosion resistance and machinability. Additionally, it features good strength-toughness, creep resistance, and stress relaxation resistance.
Applications of 2Cr11NiMoNbVN
This material is mainly used for high-temperature components such as high-pressure section blades of steam turbines and gas turbine nozzles. It can also be applied to equipment parts subjected to high temperature and pressure in the petrochemical industry, and has certain applications in scenarios such as auxiliary components of aero-engines.
