Tape khn32t - эп670
Advantages and disadvantages
The tape surface is resistant to oxidation at high temperatures in an oxidizing atmosphere under the action of ammonia and nitrogen. High ductility of the alloy allows laminating tape of minimum thickness. High electrical resistance (1.1 Omhm2/m) makes extensive use of the tape in electrical engineering. Its main drawback is that it does not have stability in the atmosphere of sulfur compounds and sulfur. this tape has a high cost, the high cost of basic components — chromium and Nickel.
Production
The percentage composition of the steel is regulated by GOST 5632−72. The alloy is melted in open induction furnaces, which ensures a minimum content of impurities.

Basic properties
The surface of the tape is not subject to oxidation during long-term operation and high temperature. Density = to 8.16 g/cm3, coefficient of linear expansion of 13.7 (1/deg K). The mechanical properties are temperature dependent. The tape has a coefficient of thermal conductivity in the range of 15.9 to 23.4 W/(m•deg K). Thanks to a good chemical composition has high weldability, which allows not to use special sophisticated equipment and extra heat treatment after welding.
Hardening
Tape marks KHN32T to provide additional rigidity is subjected to quenching at t º 1000 — 1200ºC and then cooled in water or air. It promotes the normalization of internal stresses in the alloy and increasing the strength characteristics of parts.
