GH3536 High Temperature Alloy Steel Bar
The gh3536 alloy is mainly used for chromium and molybdenum solid solution of a high iron content of nickel-based superalloy. Has good resistance to oxidation and corrosion resistance, below 900 ℃ have moderate to the durability and creep strength, cold and hot forming and welding performance is good.
Suitable for the manufacture of aero-engine combustion chamber components and other high-temperature parts, 900 ℃ long-term use, the short-term operating temperature of 1080 ℃. In the 600 ~ 1200 ℃ high temperature can withstand a certain stress and has anti-oxidation or corrosion resistance of the alloy. According to the matrix elements can be divided into iron-based superalloy, the nickel-based superalloy, and cobalt-based superalloy.
According to the preparation process can be divided into deformation of high-temperature alloys, casting superalloys and powder metallurgy superalloys. According to the strengthening method, there are solid solution strengthening type, precipitation strengthening type, oxide dispersion strengthening type and fiber strengthening type (see metal strengthening).
High-temperature alloys are mainly used in the manufacture of aerospace, naval and industrial gas turbine blades, guide vanes, turbine discs, high-pressure compressor pan and combustion chamber and other high-temperature components; also used in the manufacture of spacecraft, rocket engines, nuclear reactors, petrochemical equipment and Coal conversion and other energy conversion devices.
