Original Title: GH1015 (GH15, GR5) Superalloy Plate | Pipe | Strip GH1015 I. Introduction of GH1015: GH1015 is a FE-NI-CR based solution strengthened wrought superalloy, which is used at temperatures below 950 degrees. The alloy is solution strengthened by adding elements such as chromium, tungsten and molybdenum. The alloy has high plasticity, medium endurance and creep strength, good cold and hot fatigue resistance, good processing and welding performance and structural stability. The main products are cold rolled sheet, titanium bar gr5 , wire and forgings. II. Application and characteristics of GH1015: GH1015 alloy has been used to manufacture plate structural steel and other high-temperature components such as aero-engine combustion chamber and afterburner cylinder. The alloy has a certain age hardening phenomenon when working for a long time at the temperature of 700 deg C to 900 deg C, so that the room temperature plasticity is reduced; and the alloy has a tendency to be oxidized along the grain boundary when working for a long time at the temperature of more than 700 deg C, so that an enamel coating can be used for effective protection. The high temperature oxidation resistance above 1000 degrees is slightly worse than that of nickel-based alloys for similar purposes. III. Similar grades of GH1015: High temperature new name: GH1015 High temperature old name: GH15 New name for corrosion resistance Old name for corrosion resistance GB grade: GR5 The alloy can be used as a substitute for GH2039, GH3030, GH3044 and GH3536 alloys.
