Cr20Ni40 is a widely used nickel-chromium high-temperature electric heating alloy. With its excellent comprehensive performance, it has become one of the core materials in the medium and high-temperature heating field. This alloy takes nickel and chromium as the main components, with precisely controllable component ratio, ensuring stable resistivity of the product. When energized and heated, it generates heat evenly without obvious temperature fluctuation, which can effectively improve the working efficiency of heating equipment. It has excellent high-temperature oxidation resistance, with a long-term service temperature of up to 1100℃ and a short-term maximum service temperature of 1200℃.
Under high-temperature working conditions, it is not easy to oxidize and peel, not easy to embrittle, has minimal deformation, can maintain structural stability for a long time, and significantly extend the service life of equipment.
Cr20Ni40 alloy has a dense structure and low impurity content, with excellent cold and hot workability. It can be processed into wires, strips, bars and various special-shaped parts according to actual needs, adapting to the installation and use needs of different scenarios, and can complete assembly without complex processing technology. The product has stable electrical performance and small temperature coefficient of resistance, which can maintain stable heating effect in different temperature environments. It is widely used in industrial electric furnaces, heat treatment furnaces, resistance furnaces, heating elements, resistors, high-temperature structural parts, etc., covering metallurgy, machinery manufacturing, chemical industry, electronic appliances, new energy and other industries.
The product is produced in strict accordance with industry standards and has passed multiple quality inspection procedures to ensure uniform chemical composition, up-to-standard dimensional accuracy and stable and reliable performance. It can effectively adapt to the high-temperature working conditions of long-term continuous work and solve the pain points of traditional alloys that are easy to be damaged at high temperatures and have a short service life. Whether it is a conventional heating scenario or a high-temperature heating demand under complex working conditions, Cr20Ni40 can show excellent adaptability, making it a cost-effective and practical industrial high-temperature electric heating alloy material.
