The main alloying elements are chromium, tungsten, molybdenum, cobalt, aluminum, titanium, boron, zirconium and so on. Among them, chromium plays an anti-oxidation and anti-corrosion role, and other elements play a strengthening role. It has high strength, oxidation resistance and gas corrosion resistance at high temperature of 650~1000 ℃. It is the most widely used and the highest high temperature strength alloy. Mainly used in the manufacture of aero engine blades and rocket engines, nuclear reactors, energy conversion equipment on the high-temperature parts.

Brief Analysis on Supply and Demand of High Temperature Alloy Industry in China
With the rapid development of aerospace, nuclear power and other fields in China in recent years, the market demand for high-temperature alloys is also increasing, which promotes the growth of high-temperature alloy production in China. Although my country's high-temperature alloy industry has developed rapidly, there is still a gap between the overall technical level and the world's advanced level. High-end varieties have not yet achieved independent control, and the gap between supply and demand is large.

Classification and Composition Comparison of Nickel-based Alloys
Nickel-based alloy electrodes can be divided into five categories, namely, industrial pure Ni, Ni-Cu, Ni-Cr-Fe, Ni-Mo and Ni-Cr-Mo. Each type can be divided into one or more types of electrodes. This type of electrode is mainly used for welding nickel or high nickel alloy, and sometimes can also be used for welding or surfacing of dissimilar metals.

Stress corrosion. Under the combined action of corrosive medium and high tensile stress, the metal surface is corroded and expands into micro cracks, which often leads to sudden breakage. This failure can occur with high-strength steel bars (wires) in concrete.

Nickel base alloy knowledge introduction, nickel base alloy application in what areas?
Nickel-based alloys composed of other elements are called nickel alloys. Nickel has good mechanical, physical and chemical properties, adding suitable elements can improve its oxidation resistance, corrosion resistance, high temperature strength and improve some physical properties. Nickel alloys can be used as materials for electronic tubes, precision alloys (magnetic alloys, precision resistance alloys, electric heat alloys, etc.), nickel-based high-temperature alloys, nickel-based corrosion-resistant alloys, and shape memory alloys. Nickel alloys are widely used in energy development, chemical industry, electronics, navigation, aviation and aerospace.
