High temperature Ni-Alloy Steel Solid Bar GH3030 GH3039 GH4141 High-Temperature Alloy Round Rod

High-temperature alloy refers to a type of metal material based on iron, nickel and cobalt, which can work for a long time at high temperatures above 600℃ and under certain stress; and has high high-temperature strength, good oxidation resistance and corrosion resistance, good fatigue performance, fracture toughness and other comprehensive properties. High-temperature alloy is a single austenite structure, with good organizational stability and reliability at various temperatures.

Based on the above performance characteristics, and the high degree of alloying of high-temperature alloy, it is also called "superalloy", which is an important material widely used in aviation, aerospace, petroleum, chemical industry, and ships. According to the matrix elements, high-temperature alloys are divided into iron-based, nickel-based, cobalt-based and other high-temperature alloys. The use temperature of iron-based high-temperature alloys can generally only reach 750~780℃. For heat-resistant parts used at higher temperatures, nickel-based and refractory metal-based alloys are used. Nickel-based high-temperature alloys occupy a particularly important position in the entire field of high-temperature alloys. It is widely used to manufacture the hottest parts of aviation jet engines and various industrial gas turbines.

1. Melting

   The process begins with the melting of high-purity raw materials in an electric arc furnace or induction furnace. The molten metal is then refined to remove impurities and achieve the desired chemical composition.

2. Casting

   After refining, the alloy is cast into ingots. These ingots are typically subjected to a homogenization heat treatment to eliminate segregation and enhance uniformity.

3. Forging

   The ingots are then hot-forged at temperatures above 1100°C to achieve the desired shape and grain structure. This step is crucial as it refines the microstructure and improves the mechanical properties of the alloy.

4. Hot Rolling

   Following forging, the material undergoes hot rolling to reduce the thickness and achieve the final dimensions of the bars. This process also enhances the directional properties of the alloy.

5. Annealing

   To relieve internal stresses and improve ductility, the rolled bars are annealed at temperatures around 900-950°C. This step ensures the material is ready for final machining and use.

6. Finishing

   The final step involves cutting the bars to the required lengths and applying any necessary surface treatments. This may include grinding, polishing, or coating to protect against environmental factors
