Relevance
Brand 03KH22N6M2 relates to chromium-Nickel-molybdenum steels austenitic-ferritic class. Used in the manufacture of welded tanks involved in the synthesis of mineral fertilizers, acetic and sulfuric acid, caprolactam and urea. Permissible operating temperature is from -70 to +300°C. This steel, like brand 08KH21N6M2T (ЭП54) are an alternative to alloy 10X17H13M2T.

Production
Is carried out according to technical conditions TU 14−1 — 1905−76 and the following GOST: 7350−77 and 5632−72. 03KH22N6M2 steel is smelted in electric arc furnaces. Classified as stainless steel, corrosion-resistant, plain, heat-resistant steel. It meets the strict requirements of the state standard, fairly easy cuttability. Plastic deformation is carried out in the temperature range from 1170 °C to 900 °C.
Physical properties at 20°C
— Specific gravity: 7.7 g/cm3
— The modulus of elasticity of 18x10— 4 N/mm2 and at a temperature of 300 °C decreases to 15.9x10— 4 N/mm2
— Electrical resistivity 0.7 Omhm2/m
— The hardness of the steel is 200 MPa -1 NV.
— Magnetic permeability in a field of 500 e of 0.6 (T · m)/A.
Welding
Is both automatic and manual electric-arc and argon-arc method. Sheet thickness not exceeding 10 mm welded by all methods of manual arc welding satisfactorily. TIG method is recommended for sheets less than 6 mm in thickness and for welding root passes of more than 10 mm. larger items satisfactorily welded two types of manual arc welding with a low content in the metal of niobium in the root pass of the weld. 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. For sheet thickness of over 12 mm using a combined method (argon arc welding and welding with stick electrodes). Seams are addressed to a corrosive environment, are welded to the electrodes OzL-17U.
Use
Production of welded chemical equipment, heat exchangers, chemical reactors, pipelines. Also the steel used in the manufacture of castings for tanks, parts of metallurgical mining and chemical equipment which are operated in wet-process phosphoric acid, 55% sulfuric acid and acetic acid and similar corrosive environments, to a temperature of 80 °C.
03KH22N6M2 steel used in equipment designed for the production of mineral fertilizers. This steel can be used for the manufacture of compounds of fittings in piping joints, repair welds equipment that operates in a radioactive environment and tubes to the housing of the apparatus. Steel 03KH22N6M2 demand for coils of the tubular furnace, as a cladding layer in the rolling centrifugal cast iron pipe and 2-layer corrosion-resistant hot-rolled sheets, plants for the production of ammonia, ethylene, carbon disulfide, etc.substances.
