Product information

Brand: GH3128
Steel Works: Haynes; SMC; ATI; VDM; Outokumpu; NYK; Nippon Steel, Fushun/Northeast Special Steel, etc
GH3128 (GH128) is a nickel-based alloy strengthened with tungsten and molybdenum solid solution and reinforced with boron, cerium and zirconium. It has high plasticity, high persistent creep strength, good oxidation resistance, stamping, welding and other properties. Its comprehensive properties are superior to those of GH3044 and GH3536 similar nickel-based solid solution alloys. It is suitable for the manufacture of combustion chamber flame cylinder, afterburner shell, adjusting plate and other high temperature parts of aero engine working at 950℃ for a long time. The main products are cold rolled sheet, but also can supply hot rolled plate, bar, forgings, wire and pipe. Delivery state solution temperature is 1140 ~ 1180℃, air cooling. The high temperature performance was tested after solution treatment at 1200℃. Cold-rolled sheet 0.8 ~ 4.0mm, hot-rolled plate 4 ~ 14mm, cold-drawn wire Φ0.3 ~ 10mm. Cold rolled and hot rolled plates in solution and pickling; Welding wire in cold drawn, semi-hard or solid solution and pickling state. Electroslag remelting in non-vacuum or vacuum induction furnace. The alloy is suitable for the manufacture of aero engine combustion chamber and afterburner parts working below 950℃, and the use effect is good

Product parameter

Chemical composition
‌‌ nickel (Ni) ‌ : GH3128 alloys contain a large amount of nickel, usually more than 50% of the total weight. Nickel can improve the oxidation resistance, corrosion resistance and high temperature strength of the alloy, but also improve the plasticity and toughness of the alloy, reduce the coefficient of thermal expansion.
‌‌ chromium (Cr) ‌ : Chromium content is generally between 19% and 22%. Chromium can improve the oxidation resistance and corrosion resistance of the alloy, but also improve the hardness and strength of the alloy, as well as wear resistance.
‌‌ tungsten (W) ‌ : Tungsten content is generally between 0.4% and 2.0%. Tungsten can improve the high temperature strength and hardness of the alloy, as well as wear and corrosion resistance.
‌ molybdenum (Mo) ‌ : The content of molybdenum is generally between 7.5% and 9.0%. Molybdenum can improve the high temperature strength and corrosion resistance of the alloy, but also improve the plasticity and toughness of the alloy.
‌‌ iron (Fe) ‌ : The iron content is generally between 1.0% and 2.0%. Iron can increase the high temperature strength and hardness of alloys.
‌‌ aluminum (Al) ‌ : The content of aluminum is generally between 1.0% and 2.0%. Aluminum can improve the high temperature strength and corrosion resistance of the alloy, but also improve the plasticity and toughness of the alloy, and reduce the coefficient of thermal expansion.
‌ titanium (Ti) ‌ : The content of titanium is generally between 0.4% and 0.8%. Titanium can improve the high temperature strength and corrosion resistance of the alloy, and also improve the plasticity of the alloy.
Mechanical property
‌ tensile strength ‌ (MPa) ≥750, indicating that the alloy can withstand large mechanical loads in the temperature range from room temperature to 950℃.
‌ yield strength ‌ (MPa) ≥400, which means that the alloy can resist plastic deformation when subjected to external forces until a certain stress level is reached.
‌ elongation ‌ (%) ≥30, indicating that the alloy has good plasticity and can withstand a certain degree of plastic deformation before fracture, which is helpful to absorb energy and reduce impact damage to the structure.
‌ hardness ‌ (HB) 200-230, indicating that the alloy can resist slow plastic deformation under prolonged heat and continuous stress
