Processing
The following rolled products are produced: round, pipe, wire, sheet, strip. During plastic deformation, the temperature range is 1170 °C at the initial stage and about 900 °C on completion. Welding can be done manually or automatically. During manual arc welding electrodes OZL-24 with a wire rod 02Х17Н14С4 are used. This type of filler material is also used for automatic arc and argon arc welding. To protect the welds, a final heat treatment is used.
Use
Production of welded chemical apparatus for the synthesis of mineral fertilizers, heat exchangers, reactors, pipelines. Manufacturing of vessels operated in extractive phosphoric, 55% sulfuric and acetic acids and other highly corrosive environments, at temperatures up to 80 °C. Production of welding wire and welding electrodes CB-02Cr8H22C6, demanded for joints of fittings, in the joints of pipelines, repair of welded equipment, which operates in a radioactive environment. Alloy 02Cr18N116 is used as a cladding layer in the production of two-layer hot-rolled stainless sheets, centrifugally cast pipes, for coils of tubular furnaces and equipment for the production of ethylene, ammonia and carbon disulfide.
