Basic qualities

Doping of chromium-nickel steel KhN45Yu with aluminum, manganese and silicon increases resistance to contact with an aggressive medium. When heated, these substances form strong oxidic protective films on the surface. The main advantage of wire, circle, bar of brand ХН45Ю is considered resistance at high temperatures in aggressive gas environments. The main performance characteristics of these materials are fully determined by the chemical composition, and the duration of operation depends on the operating conditions of the particular part (level and load patterns). Most often wire, circle, rod ХН45Ю is used in thermal installations. High heat resistance directly depends on the structure of the substance and strong bonds in the alloy between the atoms.
