GH80A High Temperature Alloy Steel bar


GH80A is based on nickel - chromium as the matrix, the addition of aluminum, titanium formation of r - phase dispersion of the strengthening of high - temperature alloys, in addition to slightly higher than the aluminum content, the other and GH4033 similar to the use of temperature 700 ~ 800 ℃, 650 ~ 850 ℃ Creep performance and oxidation resistance. The hot and cold processing of the alloy is good, the main supply hot-rolled bar, cold-drawn bar, hot-rolled sheet, cold-rolled sheet, strip and ring, etc., for the manufacture of engine rotor blades, guide vane bearing, bolts, Lockplate and other parts.
