Sheet HN77TYUR - Ei437bu
Stainless steel sheet heat resistant alloy HN77TYUR with Nickel basis is a multifunctional material with unique capabilities. Its surface is not subject to oxidation during long-term operation and high temperature. The quality of the sheet allow you to apply all the modern technology of metal: grinding, cutting, polishing.
|The chemical composition of the alloy, in percent.|

The alloy is melted in open electric furnaces, which ensures a minimum content of impurities. Percentage composition is regulated by GOST 5632−72. Flat rolled comes in the form of hot rolled and cold rolled sheets and strips of thickness 0.5 to 12 mm. in the manufacture of the sheet may be differences in the degree of traction, precision rolling, variety of surface treatment, sizes cutting, edge. A large range of sizes produced sheets can facilitate the selection of more appropriate blanks for details. At increased requirements to the material is hardening the strip at a temperature of about 1100 °C with subsequent cooling in water or air. Aging occurs at a temperature of 700 — 750 °C for 5−16 hours depending on the thickness of the tape. This heat treatment promotes the normalization of internal stresses in the alloy and increasing the strength.
