Manufacture and Use
Mark 03N18K8M5T-VD is smelted in an open induction furnace, using a vacuum arc remelting, according to TU 14−1-3140−81; 14−1-4479−88. Use for loading parts, axles, fastening fittings, pressure vessels. Thanks to the alloying elements, the surface is covered with a solid film material nature of the oxide in contact with atmospheric air, which reliably protects against the harmful effects of aggressive environment. Nickel gives plasticity composition, molybdenum and cobalt — heat resistance, silicon and manganese additives improve the processability of the material.
