General characteristics

Alloy 03Х24Н6АМ3 refers to hromonikelevoj steels austenitic-ferritic class. Production is carried out according to the following specifications:14−1-4372−87, 14−1-3880−84, 302.02.095−90, 14−1-5021−91. This alloy is very durable, it can be used in the conditions of erosion and corrosion wear. It is used in the manufacture of welded chemical equipment for the synthesis of urea, caprolactam, wet-process phosphoric acid and fertilizers, for the production of equipment operating in nitrate, phosphate and sulphate environments, environments rich in hydrogen sulfide and chlorides. Temperature range of operation is -40 to + 300 °C.

The chemical composition of the alloy 03Х24Н6АМ3

Such steel is produced in electric arc furnaces. It is classified as stainless steel, corrosion-resistant, plain, heat-resistant steel. It meets the strict requirements of the state standard. Well handled by way of cutting, expanding the possibilities of its use. During the hot forging, rolling and forging products in the initial stage of the technological process temperature range equal to 1170 °C, and at the end of the process it is 900 °C.

Main features at a temperature of 20°C

-The thermal conductivity is 0.168 · 102 W/(m · K);

Density of 7.7 g/cm³

— The modulus of elasticity is equal to 20 · 10^-4 N/mm²;

Hardness HB 200 MPa -1.

-Resistivity is 0.74, Mhmm²/m;

— Magnetic permeability in a field of 500 e reaches to 0.3−0.5 (T · m)/A.

Welding

Provided by an automatic; manual arc and TIG welding. 03Х24Н6АМ3 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 thick and for the implementation of the 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 the appearance of seams, of a thickness exceeding 10 mm hot cracks, root connection, you need to obratnoystorone welding 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 latter by electrodes OzL-17U.

The electrodes OzL-26A, OzL-17U and anv-17 with wire rod St-01Х19Н18Г10АМ4 well suited for manual welding of steel sheet thickness not exceeding 10 mm, as well as to fill the cutting steel with a thickness more than 10 mm. Electrodes without the presence of the coating niobium grade OzL-26A with wire rod OzL-17U — recommended for welding steel root pass thickness greater than 10 mm. the Electrodes EA-395/9 are recommended for welding steel 03Х24Н6АМ3 with steel 10X17H13M2T, 08KH18N10T, 10H17N13MZT, STZ and 20K.

In manual TIG welding with non-consumable electrode steel sheet thickness of 10 mm, and in order to fill cutting steel thicker than 10 mm, recommended wire SV-03Х23Н28МЗДЗТ and wire 02Х21Н21М4ГБ (ЗИ69). For welding root passes, steel, with thickness more than 10 mm, recommended wire 03Х24Н6АМ3; for automatic welding — steel wire SV-01Х19Н18Г10АМ4 (ЭП690) and flux an-18. The strength of the weld seams is 90 percent of the base metal. Connection of all types of welding are resistant to intergranular and General corrosion.

Use

Production of welded chemical equipment for the synthesis of urea, caprolactam, wet-process phosphoric acid and mineral complex fertilizer production equipment, operated in nitrate, phosphate and sulphate environments, environments rich in hydrogen sulfide and chlorides. Also the steel used in the production of castings for details of the metallurgical and mining equipment, vessels that operate in acid solutions at temperatures up to 80 °C, in equipment designed for the production of mineral nitrogen fertilizers.

Such steel is 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. This steel is applied as a cladding layer on tsentrobezhnolityh of the tube, the tube furnace coils and hot rolled dual-layer corrosion-resistant sheets.
