Seamless Pipe 199 Welded Pipe

Original Title: GH4199 Forged Ring GH199 Seamless Pipe 199 Welded Pipe XH56BMT XH56BMT Bright Pipe Buchmann GH199 Pipe Nickel-based superalloy series materials-Shanghai BSM Special Steel Group GH4199 high temperature corrosion resistant alloy GH4199 Overview: GH4199 is a Ni-Cr based precipitation hardening wrought superalloy with service temperature below 950 ℃. Tungsten, molybdenum and chromium are added into the alloy for solid solution strengthening, aluminum and titanium are added to form an aging strengthening phase, and boron and magnesium are added to purify and strengthen a grain boundary. The alloy has high strength, good oxidation resistance and weldability, and the comprehensive properties of the alloy are good, the tensile strength at 900 ℃ is more than 490 MPa, and the alloy is one of the alloys with the highest service temperature in precipitation hardening plates. Application overview and characteristics of GH4199: The alloy has been used to make heat shield of afterburner,titanium plate gr7, adjustable nozzle heat shield, sleeve and other welded load-bearing components and airborne equipment parts for aero-engines below 950 ℃, and the batch production and use are in good condition. Because of the high degree of alloying and the large tensile deformation,titanium round bar, the hot and cold processing plasticity of the alloy is poor. The cold deformation of forging (rolling) pass should be strictly controlled in the processing to avoid processing cracks. The σ phase precipitates after long-term aging at 700 ℃ ~ 800 ℃.
