KHN65MV - ЭП567 tape

KHN65MV - ЭП567 tape

General characteristics

Heat resistant tape KHN65MV is designed to work in aggressive environments at a temperature of 700 — 850 °C. its Rate of oxidation in the relaxed atmosphere of the air is 0.03 mm/year at 800 °C. This tape is non-magnetic, corrosion resistant. At 20 °C has a high limit (500 MPa) and short-term strength up to 180 MPa — yield point and low elongation at break — 30%. Temperature during ruskovce reduced from 1170 °C to 850 °C at the end. The finished strip is cooled in air.

Tape 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. This tape is resistant to an oxidizing atmosphere, to an atmosphere of ammonia and nitrogen. Its main drawback is that it does not have stability in the atmosphere of sulfur compounds. The high cost of tape tied to the high cost of the main components — Nickel.

Properties

Tape KHN65MV plastic and is resistant in an oxidizing atmosphere, ammonia atmosphere and nitrogen. Its surface is resistant to oxidation during long-term operation and high temperature. The coefficient of linear expansion = 13.7 per (1/deg K). Density of 8.9 g/cm3. The mechanical properties of the ribbon depend on the temperature. Up to t º 800ºС the resistance of the load will be maximum. Coefficient of thermal conductivity in the range in the range 20 — 100 º C = 0,126 • 102 W/(m • K).

Welding

Is arc or TIG welding. For TIG welding the filler material used wire KHN65MV and KHN65MVU. For arc welding use electrodes OzL-21. Welded connections are not prone to hot and cold cracking and resistant to intergranular corrosion.

Heat treatment

Tape marks KHN65MV at elevated strength requirements, subjected to quenching at t º 1000 — 1200ºC with further cooling in water or air. Such heat treatment promotes the normalization of internal stresses in the alloy and increase long-term strength of the parts.
