12CrMo is a steel alloy typically used in the manufacturing of industrial components, primarily those exposed to high temperatures such as high-pressure vessels and pipes.
12CrMo is an alloy steel composed of 12% chromium and 0.25-0.35% molybdenum as primary alloying elements. This material offers high tensile strength and medium yield strength. In a normalized condition, it has a good ductility and can be easily machined and welded. 12CrMo is mostly used for the production of pressure vessels, boilers and components operating at elevated temperatures.
Due to its excellent creep resistance, 12CrMo is the preferred material for high-temperature applications, such as superheater and reheater tubes in fossil fuel-powered plants. It also offers oxidation and corrosion resistance, making it suitable for use in the chemical, petrochemical, and power plants. Moreover, this material boasts good weldability and formability properties, allowing for easy repairs and modifications.
In terms of its mechanical properties, 12CrMo is capable of displaying high strength at temperatures of up to 550°C. At these temperatures, it exhibits very low creep elongation and deformation, increasing the material’s durability and reliability. Even under continuous heating and continuous cooling cycles, the material’s mechanical characteristics remain stable over time.
Other industries that use 12CrMo include aerospace, defense, and marine. It can be used to produce sea vessels and airframes, turbine blades, support structures, and fuel tanks. Additionally, this alloy has been used for the production and repair of high-performance motorsports vehicles.
To summarize, 12CrMo is an alloy steel that’s known for its superior creep resistance and high-temperature strength. It’s an ideal choice for the manufacturing of components exposed to elevated temperatures and aggressive environments, such as power plants, petrochemical plants and aerospace applications. 12CrMo’s attributes also make it suitable for motorsports and marine applications.
