H65M-vi (circle, wire, tube, sheet, strip) (ep982-vi)
Production
Heat-resistant steel H65M-VI (ep982-vi) contains 65% nickel, and additives of chromium, molybdenum, tungsten. The alloy also contains iron, silicon, manganese, sulfur, bismuth, carbon, and phosphorus. Nickel for the alloy is obtained by electrolysis, the method of decomposition into components of complex substances by means of an electric current. This alloy is produced in accordance with the following TU: 14-1-3281-81; 14-1-2674-79; 14-1-2879-80; 14-131-685-86; 14-1-4673-89; 14-1-4202-87; 14-3-1478-87; 14-1-4719-89. It is melted in vacuum induction furnaces. Such alloy is used in the production of chemical welded equipment operating in highly corrosive environments (hydrochloric acid, phosphoric acid, sulfuric acid solutions, acetic and hydrogen halide acids) at temperatures from -70 to + 500 °C, and pressures ~5 N/mm².

All steel products of the specified grade: bars, wires, strips, tubes etc. are produced under severe quality standards with the help of high-tech equipment.
Main properties
This steel is capable of withstanding the impact of gaseous, liquid aggressive environments at temperatures up to 850 ° C. Various kinds of processing (rolling, turning, drawing, punching, welding) are made due to plasticity of the alloy. The only drawback of alloy H65M-VI is a sulfur content, which can form a sulfide film on the surface of nickel products, making the metal more brittle and fragile at high temperatures.
Applications for
The main consumers of this steel are the chemical, pulp and paper industry, machine building, as well as research institutes and laboratories of physics and chemistry. Pipes made of this steel grade can be used almost without restriction in industrial chemistry. They are difficult to replace in alkali and acid distillation technology. Sheets and strip are very popular in mechanical engineering and instrumentation. This alloy is used to produce equipment that is needed for the synthesis of acetic acid from methanol and carbon oxide, ion exchange resins, polypropylene, chemical-pharmaceuticals and other organic synthesis products.
