Wire 68nhvktyu — ep578
general characteristics
Wires brand 68NHVKTYU-VI (formerly known as EP578-vi) is carried out according to specifications 14−1-4470−88. It belongs to the group of heat-resistant steels with high precision characteristics of elasticity. Different resistance even at high temperatures for a long time. Popular this wire does what it’s extremely durable, actively resists oxidation in the nitrogen or ammonia. This allows you to use it widely in the manufacture of industrial and consumer electronics. Such technological characteristics such as heat resistance, heat resistance and ability to withstand hostile environments, is achieved through alloying elements cobalt, titanium, tungsten, niobium. The main drawback of instability to the atmosphere is considered to sulfur compounds. The relative high cost of the wire is connected with the high cost of nickel — the main component of the alloy.
