Inconel 690 / 2.4642 / KhN70Yu

Heat-resistant metal based on Inconel 690 alloy belongs to the family of chromium-containing steels. It contains nickel and chromium, which guarantee the highest strength of the material, as well as resistance to any aggressive environment.

Special steels and alloys of this type are quite in demand in modern conditions. The growth of industry and production has led to the emergence of new industries that often use critical temperatures. It is the resistance to aggressive impact that makes Inconel 690 alloy very popular.

Features and applications

Inconel 690 alloy is characterized by a high content of such an element, like chrome. This guarantees excellent water corrosion resistance. In addition, products based on Inconel 690 are resistant to the most common acids and alkalis, including the most aggressive nitric acid.

Excellent anti-corrosion properties, increased strength, excellent metallurgical parameters, the ability to simple processing and welding makes the use of the alloy economically justified. The composition of steel also contains such a component of heat-resistant alloys as cobalt, which makes it possible to use it in nuclear power engineering and industry.

The main scope of application is the production of steam generator pipes, thermal installations and equipment.
