Iron based alloy/Nickel-based alloy/Nickel-based alloy/Corrosion resistant superalloy superalloy plate
Product introduction
Nickel-based superalloys are a class of precipitation strengthened alloys that perform well in high-temperature environments. The excellent high-temperature properties of nickel-based superalloys have resulted in the implementation of this class of alloys into many aerospace applications.
Iron-based superalloy is a kind of superalloy. It is characterized by adding other elements on the basis of iron for alloying. Corresponding to iron-based superalloys are nickel-based superalloys and cobalt-based superalloys.
Cobalt-based superalloys are materials used in high temperature and extreme environments with excellent high temperature strength, corrosion resistance and wear resistance. Cobalt-based superalloys are mainly composed of elements such as cobalt, chromium, tungsten, nickel and aluminum.
Corrosion resistant super alloys provide an increase in mechanical strength, resistance to thermal deformation, and resistance to corrosion compared to traditional alloys, requiring less maintenance and better withstanding harsh environments. Efforts are underway to make new corrosion resistant super alloys such as aluminum-based super alloys, and to create new methods of manufacturing such as radiolysis which utilizes nano-particle synthesis for polycrystalline formation.

Features
1, high temperature resistance, corrosion resistance
The high temperature resistance and corrosion resistance of superalloy mainly depend on its chemical composition and structure. Taking Inconel718 nickel-based deformed superalloy as an example, the alloy consists of a γ matrix phase, a δ phase, a carbide, and a strengthened γ' and γ "phase. The chemical elements and matrix structure of Inconel718 alloy show its strong mechanical properties, the yield strength and tensile strength are several times better than 45 steel, and the plasticity is also better than 45 steel. The stable lattice structure and a large number of strengthening factors contribute to its excellent mechanical properties.
2. High processing difficulty
Due to the complex and harsh working environment of superalloys, the integrity of the machined surface plays a very important role in its performance. However, superalloy is a typical difficult to process material, its micro-strengthening item hardness is high, the degree of work hardening is serious, and it has high shear stress and low thermal conductivity, cutting force and cutting temperature in the cutting area, often appear in the processing of low surface quality, tool damage is very serious and other problems. Under general cutting conditions, the surface layer of superalloy will produce too large problems such as hardened layer, residual stress, white layer, black layer and grain deformation layer.
Product Paramenters
Superalloys are heat resistance alloys of nickel, iron-nickel, and cobalt which can be used at high temperatures, often >70% of their melting temperatures. They can be used at temperatures exceeding 1050°C with excursions up to 1200°C. This temperature resistant characteristic makes it a suitable replacement candidate for Tungsten Carbide in Pick Up applications.
The most widely applied type of Superalloy is nickel-based material that contains a high concentration of chromium, iron, titanium, cobalt and other alloying elements. As with other metal material groups, the properties of superalloys can be adjusted with various heat treatments and/or annealing and quenching. Compared to other material groups, Superalloys have the highest maximum service temperature and highest hardness values. The strength of Superalloys makes it the best alternative to Carbide in high bond force applications (>1kg).
