Brand 08KH17N15M3T (ЭИ580) refers to the type of high alloyed austenitic steels. Has a high resistance to intergranular corrosion of the base metal and welds in corrosive environments up to 80 °C. Used in the manufacture of welded equipment for urea synthesis urea, phosphoric acid, and also in contact with other corrosive media in cases where the use of steel with a lower Nickel content causes corrosion in the focal areas of S-ferrite.

Steel of this brand is made in electric arc furnaces in full compliance with the strict requirements of state standard.
Made the following types of rentals: circle, tube, wire, sheet, ribbon. Production is regulated by the following GOST: 18 907−73; 5632−72; 25 054−81; 18 143−72; 5949−75; 7350−77; 4405−75; 9941−81; 9940−81. In forging, rolling and forging in the initial stage of the process temperature is 1170 °C, and at the end — of about 900 °C. This steel can be processed by the method of cutting, which extends the possibilities of its use.

The automatic, gas-electric, electric arc method. Sheet thickness up to 10 mm easy to weld arc process. TIG option is recommended for sheets less than 6 mm thickness and welding of root passes of more than 10 mm. In order to prevent welds over 10 mm hot cracks, root connection, you need to welding back-step method using the welding components without niobium. Sheet thickness of over 12 mm is welded with a combined method (argon arc welding and welding with stick electrodes). Seams are addressed to a corrosive environment, imposed to the electrodes OzL-20.
The manufacture of welded chemical equipment for the manufacture of urea synthesis urea, and fertilizers. Also used in the manufacture of containers which are operated in wet-process phosphoric, 55% acetic acid, and other environments of increased aggressiveness at temperatures up to 80 °C. is Used for the manufacture of welding electrodes 08KH17N15M3T required for connections of fittings, joints in pipelines, repair welds equipment that operates in a radioactive environment.
