Alloy 03X23H6

Technical characteristics

Alloy 03X23H6 refers to chromium-nickel austenite-ferrite class steels. It is like an analogue of OZH18H11, X18H9T, 03X19AGZN10, X18H10T alloys. It is used in the production of welded tanks for the synthesis of adipic acid, nitric fertilizers, ammonium nitrate, inNitrous gas transportation pipelines to compressor coolers of the 1-2nd stage (nitric acid, nitrous gas, temperature up to 230 °C, pressure up to 1,16 N/mm2). The supplier offers high quality steel in accordance with GOST and international standards.

Manufacturing

Steel grade 03Х23Н6 is melted in electric arc furnaces. This material is classified as stainless, corrosion-resistant, common, heat-resistant and heat-resistant steel. Production is normalized by technical specifications: 14-1-1905-76, 14-1-1-1554-75 and GOST: 7350-77 and 5632-72. Plastic deformation is carried out in the temperature range from 1170 °C to 900 °C. The alloy is cut at low revolutions.

Physical properties at 20°C

- Thermal conductivity 0.168 - 10² W/(m - K).

- Specific weight 7.7 g/cm3

- Modulus of elasticity 20 - 10-4 N/mm2

- Electrical resistivity 0.74 Ohmxmm2/m

- Hardness 200 NV MPa-1.

- Magnetic permeability 0,3-0,5 (Tl - m)/A.

Welding

Alloy 03Cr23H6 is welded by automatic, electric arc manual and argon-arc method. Sheet thickness up to 10 mm is welded by all methods of electric arc manual welding satisfactorily. Argon-arc method welds sheets less than 6 mm thick and connects root seams over 10 mm. In order to prevent hot cracks in welds over 10 mm, root joints must be welded back-to-back using niobium-free welding components. For sheet metal thicker than 12 mm, a combined method (argon arc welding and welding with piece electrodes) is used. Seams facing the corrosive environment are welded with OZL-17U electrodes.

Use

Manufacturing of welded tanks for adipic acid of mineral nitric fertilizers, ammonium nitrate, tanks which are used in extraction phosphoric acid, 55% sulfuric acid and acetic acid and other high corrosive environments, at temperatures up to 80 °C.

Production of electrical thermocouple sheaths - the alloy does not contaminate thermocouple electrodes and reliably protects thermocouple wires when operating in an aggressive environment. Production of welding wire and welding electrodes that are in demand for joints of fittings, in the joints of pipelines, repair of welded equipment that operates in a radioactive environment. Steel 03Ch23H6 is used as a cladding layer of the two-layer hot-rolled stainless steel sheets, centrifugally cast tubes, coils of tube furnaces and installations for the production of ethylene, ammonia and carbon disulfide.
