What is GH1015?
Solution-strengthened iron-based superalloy is a kind of superalloy with iron as the matrix, by adding a certain amount of chromium, nickel, tungsten, cobalt and other elements, after solution treatment and aging treatment, to obtain excellent high-temperature strength, oxidation resistance and corrosion resistance. GH1015 is one of the important models, with high nitrogen content, better high-temperature mechanical properties and long-term stability.
1. Chemical composition and tissue structure.
The chemical composition of GH1015 mainly includes iron, chromium, nickel, tungsten, cobalt and other elements, of which the chromium content is high, reaching more than 20%, and a small amount of nitrogen is added to improve the strength and stability of the material. This alloy is solution treated and aged to form a strengthened phase with a face-centered cubic lattice, resulting in excellent high-temperature performance.
2. Mechanical properties and physical properties.
GH1015 has excellent room temperature and high temperature strength, its yield strength and tensile strength are higher than other similar superalloys, and has higher durable creep strength. The alloy also has good oxidation and corrosion resistance, as well as a low coefficient of expansion and excellent thermal conductivity.
3. Manufacturing process and application field.
GH1015 can manufacture parts of various shapes, such as round bars, plates, tubes, etc., through casting, forging, rolling and other processes. The alloy is widely used in high-temperature components in aerospace, energy, chemical and other fields, such as gas turbine blades, combustion chambers, turbine disks, etc. In addition, GH1015 can also be used to make key components for high-temperature stoves and industrial furnaces.
GH1015 solution-strengthened iron-based superalloy, as an important superalloy, has excellent room temperature and high temperature strength, oxidation resistance and corrosion resistance, as well as low expansion coefficient and excellent thermal conductivity. It is widely used in high-temperature components in aerospace, energy, chemical and other fields. With the continuous development and progress of science and technology, the application prospect of GH1015 will be broader.
