Leave a message
Are you looking for AMS5706 GH4738 bright annealed steel bar for high-performance applications? Our AMS5706 GH4738 steel bar is precision-machined using a bright annealing process and offers excellent creep and oxidation resistance, as well as high-temperature strength. This material is ideal for applications requiring high strength, heat resistance, and oxidation resistance. It is widely used in aerospace, manufacturing, and engineering.
GNEE provides AMS5706/GH4738 bright annealed steel bars, a nickel-based superalloy refined through vacuum induction + vacuum arc remelting (VIM+VAR) duplex melting processes, followed by bright annealing treatment (oxidation-free surface, refined grain structure), enabling stable long-term performance at 900-1000°C. The bars are available in diameters ranging from 3mm to 200mm, with surfaces presenting a uniform silver-bright finish and no oxide scale residues, and tolerances strictly complying with AMS5706 standards. Available in fixed lengths, multiple lengths, and random lengths, they come with complete documentation including original mill test certificates (MTC), spectrochemical analysis reports, mechanical property test data (tensile/impact/hardness), and third-party certification files (e.g., SGS). GNEE supports both small-batch customization and large-scale stable supply, ensuring reliable application in extreme environments.
AMS5706/GH4738 bright steel bars are suitable for aerospace engine high-temperature components (such as turbine discs, blade support rings), gas turbine hot-end parts, high-temperature molds, and heat-resistant structural components in the petrochemical industry-applications demanding stringent high-temperature performance.
