Tape 68NHVKTYU - EP578
Non-magnetic heat-resistant tape brand 68NHVKTYU-VI refers to the precision heat-resistant steel with high elastic characteristics. Has high corrosion resistance, can be maintained at t ° 500 — 800 ° C in an environment corrosive industrial gases. In still air at t ° 800 ° C Tape oxidation occurs at a rate of 0.03 mm per year.
Tape marks 68NHVKTYU-VI high-tech methods available for any machining. Wear resistance, durability, reliability, aesthetic appearance allow you to use it in many areas. It is flexible and resistant to oxidation in an atmosphere of nitrogen, ammonia is indispensable in the manufacture of industrial and household electrical appliances. The main drawback — the instability under the influence of sulfur compounds. The relative high cost associated with a high nickel content — the main component of the alloy. Heat resistance, heat resistance is achieved by alloying components. However, the rate of increase of alloying is not necessary due to the increased cost of the final product. Specifications 14−1-4470−88 normalized tolerances percentage composition.

Tape 68NHVKTYU-VI is stable for long-term operation at high temperatures. When heated, chromium, silicon, aluminum are formed on the surface of the protective film — oxides, protecting parts against further oxidation. This quality makes it very popular in various fields of modern industry: industrial chemistry, metallurgy, power engineering, instrument making.
