General characteristics

Alloy ХН40МДТЮ (ЭП543У) refers to the type of iron-Nickel alloys. Classified as stainless steel, corrosion-resistant, heat-resistant austenitic steel. Is smelted in electric arc furnaces, Used in the manufacture of welded chemical equipment (centrifugal separators, centrifuges), working in corrosive environments (in hydrochloric acid, phosphate, sulfuric acid solutions, acetic and holodnokatanyh acids, etc.). From this alloy are manufactured in sensitive elastic elements (membranes, bellows, spring) and equipment necessary for the synthesis of acetic acid from methanol oxide and carbon, ion exchange resins, polypropylene, chemical pharmaceutical preparations and other products of organic synthesis. The alloy made in accordance with the following TU: 14−1-1754−76; 14−1-1214−82; 14−1-3639−83; 14−1-4042−85; 14−1-3190−81; 14−1-3528−83; 14−1-3546−83.

The chemical composition of the alloy

Basic properties 06HN28MDT

— Magnetic permeability in a field of 500 OE at the temperature. 20 °C равна1,255 micro Tesla/m.

— Hardness = 200 HB MPa -1.

— The resistivity at the temperature.20°C is 0.75 Omhm²/m.

— Thermal conductivity at 20 °C is 0,134 · 102 W/(m · K).

— Density = of 7.96 g/cm3.

In forging, rolling and forging in the initial stage of the process temperature is 1170 °C, and at the end of the process it is 900 °C. This steel is quite easy to cut. It is welded with manual, automatic welding with flux and gas shielding. In the process of manual electric arc welding using electrodes OzL-37−2, OzL-17U with wire rod. This type of filler material is also used for automatic arc and TIG welding.

Use

Steel brand ХН40МДТЮ is widespread in the manufacture of welded chemical equipment: heat exchangers, reactors, pipelines. Also the steel used in the manufacture of metallurgical mining equipment, vessels that operate in the environment of wet-process phosphoric, 55% sulfuric acid and acetic acid, etc. aggressive environments with elevated temperatures up to 80 °C.

ХН40МДТЮ steel used in equipment designed for the production of mineral fertilizers, for the manufacture of welding wire and welding electrodes. This steel is indispensable for repair welds — fittings, joint pipe, equipment that operates in a radioactive environment, for pipe connections from the unit. Steel ХН40МДТЮ used as a cladding layer in the production tsentrobezhnolityh pipes, coils for tubular furnaces and a two-layer corrosion-resistant hot-rolled sheets, plants for the production of ethylene, ammonia, carbon disulphide, hydrogen, etc. of chemical substances. Steel ХН40МДТЮ used in the production of branded glassware, jewelry, luxury items, and is also widely used in the design.
