2.4630 superalloy is an important engineering material with excellent high temperature performance and corrosion resistance, and is widely used in aerospace, chemical industry, energy and other fields.
Chemical composition.
2.4630 superalloy is mainly composed of elements such as nickel (Ni), chromium (Cr), molybdenum (Mo) and titanium (Ti). Among them, nickel content accounts for the highest proportion, more than 50%, chromium content is about 20%, molybdenum and titanium content are about 14% and 3%, respectively. In addition, it also contains a small amount of aluminum (Al), copper (Cu) and other elements, and the reasonable ratio of these elements gives 24630 superalloy has excellent high temperature and corrosion resistance.
Hardness and density.
2.The hardness of 4630 superalloy is usually above 200HB (Brinell hardness), which has good wear resistance and high temperature strength. And its density is about 84G cm, relatively light, is conducive to reducing the structural load and improving the service life of the equipment.
Heat treatment.
2.4630 superalloy generally adopts the heat treatment process of solid solution aging (T6 state), and the grain size and morphology of the precipitated phase of the alloy are adjusted by controlling the heating temperature and holding time, so as to obtain the ideal structure and properties.
Mechanical and mechanical properties.
2.4630 superalloy can still maintain high strength and toughness in high-temperature environment, and has good tensile resistance, yield strength and ductility.
