10Cr12Ni3Mo2VN Martensitic Stainless Steel Bars and plates
It offers excellent comprehensive properties, including outstanding strength, toughness, and fatigue resistance, as well as stability in moderately corrosive environments. It is suitable for high-temperature and high-pressure service conditions. However, it has poor weldability and requires preheating and post-heat treatment to prevent cracking, and its cost is relatively high.
Applications of 10Cr12Ni3Mo2VN
It is mainly used for key components of aero-engines (such as compressor blades, turbine disks, and shaft parts), marine power systems, high-stress fasteners, and high-temperature and high-pressure equipment in the chemical and energy industries. It is also applicable to military equipment, nuclear industry components, and high-end mold manufacturing, being particularly suitable for critical structural parts serving long-term in corrosive media and complex stress environments.
