21НКМТ-VI, ВЭС130 tape, sheet, round, wire
Thanks to optimally balanced composition, structural Maraging chromium-Nickel steel 21НКМТ-VI (WPP-130) alloyed with cobalt, molybdenum, etc. chemical elements, exhibits high technological and operating characteristics: heat resistance, resistance to corrosion damage, good resistance to scale formation, which allows the semi-brand 21НКМТ-VIE to work effectively in the toughest industrial conditions. The high temperatures in the working area up to 750 °C does not reduce the operating parameters of semi-finished products of the brand 21НКМТ-VI. The high content of chromium and Nickel contributes to the formation on the surface of goods durable film coating that protects the material from oxidation and corrosion. It is particularly important to note that of steel 21НКМТ-VIE good resistance to fatigue processes and inertia in relation to the aggressive influence of the gas environment.
