KHN75MBTJU - ЭИ602 tape
Tape KHN75MBTJU (ЭИ602) is not magnetic and has heat resistance, designed to work in aggressive environments at t° 700 — 850 °C, its Surface is not subject to oxidation during long-term operation and high temperature. The rate of oxidation in the relaxed atmosphere of the air is 0.03 mm/year at t° 800 °C. with Nickel and chromium, parts made from this tape, have a high corrosion resistance, providing increased reliability of the equipment.
The composition of the alloy KHN75MBTJU regulated GOST 5632 — - 72. Tape rather technological, machinable and different methods of welding. It is durable, reliable and aesthetically pleasing, from-for what in demand in many sectors of the economy. It is ductile and resistant to an oxidizing atmosphere, to an atmosphere of ammonia and nitrogen. However, its main drawback is that it does not have stability in the atmosphere of sulfur compounds. It has a high cost, because of the high cost of the main components — Nickel.

Tape KHN75MBTJU at 20 °C has a high limit short-term strength of 500 MPa and about 180 MPa — yield strength, minor elongation at break — 30%. The temperature of the first forging is 1170 °C, and at the end of — 850 °C. the Finished product is cooled in air. The coefficient of linear expansion of 12.4 (1/deg) at 100 °C. the Density of 8.3 g/cm 3, heat — 13.45 W/(m*deg). The mechanical properties change depending on the temperature acting on the alloy. The tape has a coefficient of thermal conductivity of 0,126 • 102 W/(m • K). tape, thanks to a balanced chemical composition has high weldability, which allows a variety of designs without the use of special processing equipment and without additional heat treatment after welding.
To impart additional hardness to the applied quenching at t º 1000 — 1100ºС with subsequent cooling in water or air. It promotes the normalization of internal stresses of the material, increasing the strength characteristics of parts.
