Special steels and alloys
Production
Special steels are stainless steel rolled for special purposes, which meets the increased requirements with respect to strength, heat resistance, wear resistance, Such steels contain up to 65% of nickel, are melted in vacuum induction furnaces. The composition also includes iron, chromium, molybdenum, tungsten, silicon, manganese, bismuth. Production is regulated by 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.
Relevance
Special-purpose steel is used in the production of critical structural elements, parts of gas-turbine engines, chemical welded equipment operating in aggressive environments (in hydrochloric acid, phosphoric acid, sulfuric acid solutions) at temperatures from -70 to + 500 °C, and pressures ~5 N/mm².
Technical data
Special steel can withstand aggressive gaseous, liquid media in a wide temperature range. Various types of processing (rolling, turning, drawing, stamping, welding) are possible due to the high manufacturability of special steels Special steels serve as a basis for various types of rolled products - bands, wires, sheets, strips, pipes, etc.The disadvantage is the presence of sulfur that can form a sulfide film on the surface of nickel alloys making the metal brittle and ductile at high temperatures.
Applications
All products bars, wires, strips, tubes etc. are produced under strict quality standards using high-tech equipment. The main consumers of special steels are chemical industry, pulp and paper industry, machine industry, aircraft industry. Special steel is difficult to replace in the technology of synthesis of alkalis and acids. Sheets and strips are very popular in mechanical engineering and instrument making. 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.
| Welding: | |||
|---|---|---|---|
| Limited weldable. | - welding possible by heating to 100-120 ° C and the final heat treatment | ||
| difficult to weld | - to get high quality welded joints, it is necessary to make additional operations: during welding heating to 200-300 ° C and the final heat treatment (annealing) after welding. | ||
| Weldable without restriction | - Welding is performed without preheating and final heat treatment. | ||
