High Temperature Rod
Product Details
High-temperature alloy refers to a type of metal material based on iron, nickel, and cobalt, designed to operate for long periods at high temperatures above 600°C under stress. It exhibits high-temperature strength, good oxidation resistance, corrosion resistance, excellent fatigue performance, and fracture toughness, making it highly suitable for extreme environments. These alloys have a single austenite structure, ensuring good organizational stability and reliability at various temperatures.
Due to these exceptional properties and high degree of alloying, high-temperature alloys are often referred to as "superalloys." They are vital materials in many industries, including aviation, aerospace, petroleum, chemical, and maritime sectors. High-temperature alloys are typically classified into iron-based, nickel-based, and cobalt-based alloys. Iron-based high-temperature alloys generally reach temperatures of 750-780°C, whereas nickel-based and refractory metal-based alloys are used for applications requiring higher temperatures. Nickel-based high-temperature alloys are especially important and are extensively used in manufacturing components such as the hottest parts of jet engines and industrial gas turbines.

Manufacturing Process
Melting
The process begins with melting high-purity raw materials in an electric arc furnace or induction furnace. The molten metal is refined to remove impurities and achieve the desired chemical composition.
Casting
Once refined, the alloy is cast into ingots, which are then heat-treated to eliminate segregation and ensure uniformity.
Forging
The ingots are hot-forged at temperatures above 1100°C to form the desired shape and improve the alloy's microstructure. This step enhances the mechanical properties of the material.
Hot Rolling
Following forging, the material is hot-rolled to reduce thickness and achieve the final bar dimensions, improving the alloy's directional properties.
Annealing
The rolled bars are annealed at temperatures around 900-950°C to relieve internal stresses and improve ductility, preparing them for final machining.
Finishing
The final step involves cutting the bars to required lengths and applying surface treatments such as grinding, polishing, or coating to protect against environmental factors.
Applications
