High-Temperature Alloy Market - A 30 Billion Yuan Sector

Definition of High-Temperature Alloy

High-temperature alloys are a class of metal materials based on iron, nickel, and cobalt that can work for a long time at temperatures above 600°C and under certain stress; they have high-temperature strength, good oxidation resistance, corrosion resistance, good fatigue performance, fracture toughness, and other comprehensive performance. High-temperature alloys have a single austenite structure and exhibit good structural stability and reliability at various temperatures. Due to the above performance characteristics and the high degree of alloying, high-temperature alloys are also known as "superalloys" and are widely used in aviation, aerospace, petroleum, chemical industry, and naval vessels. Based on the matrix element, high-temperature alloys are divided into iron-based, nickel-based, and cobalt-based high-temperature alloys. Iron-based high-temperature alloys can generally only reach temperatures of 750-780°C, while for heat-resistant parts used at higher temperatures, alloys based on nickel and refractory metals are adopted. Nickel-based high-temperature alloys hold a particularly important position in the field of high-temperature alloys, widely used to manufacture the hottest parts of aviation jet engines and various industrial gas turbines.

Price Trend Tracking

Looking back at the price trend of high-temperature alloys in the past two months, as of July 9th, the price of N08810 material from Anhui Fukai Resources was reported at 66,000 yuan/ton, a cumulative drop of 15,000 yuan/ton; the price of N08825 material was reported at 98,000 yuan/ton, a cumulative drop of 13,000 yuan/ton; the price of N10276 material was reported at 217,000 yuan/ton, a cumulative drop of 24,000 yuan/ton. It can be seen that high-temperature alloy resources are also showing a weakening trend, but even if the price weakens, the demand for materials such as N08810, N08825, and N10276 still shows a steady growth.

Features of High-Temperature Alloys

Excellent High-Temperature Strength: The ability to maintain high mechanical strength in high-temperature environments, ensuring the reliability of the material under extreme conditions.

Good Oxidation and Hot Corrosion Resistance: The ability to resist the erosion of oxidation and hot corrosion, extending the service life of the material.

Good Fatigue Resistance and Fracture Toughness: Possessing excellent anti-fatigue and fracture toughness, ensuring the safety and stability of the material during long-term use.

Sensitivity to Hot Working Processes: The microstructure of the alloy is very sensitive to hot working processes, requiring precise control of heat treatment processes to obtain the best performance and part quality.

Domestic High-Temperature Alloy Market Situation

The current situation of the domestic high-temperature alloy market is characterized by a large supply-demand contradiction but has huge development potential.
