    Steel 12Х1МФ

    12H1MF -heat-resistant low-alloy steel.

    Steel 12Kh1MF – limited weldable, welding is possible when heated to 100-120 degrees. and subsequent heat treatment

    Brand 12Х1МФ – appointment

    Low-alloy heat-resistant steel of pearlitic class 12X1MF is used for the manufacture of pipes for high-pressure installations, boiler forgings, gas turbine parts. Application temperature of the brand – up to 585 0 С; service life – more than 10,000 hours. At a temperature of 600 0 С – intensive scale formation.

    Brand description 12Х1МФ

    Steel 12Kh1MF & nbsp; is used for the manufacture of parts operating at a temperature of 540-580 ° C.

    Steel grade 12X1MF belongs to heat-resistant structural types of steel. Similar steel grades that can act as substitutes: 12X1MF-PV, 13X1MF, 15X1M1F. This brand is also sometimes denoted in a different way: steel EI-575, steel 12Kh1MF, st.12Kh1MF, 12Kh1MF, 12KhMF. There is also a foreign analogue, which is designated as DIN 14MoV63.

    This type of heat-resistant steel belongs to the pearlite class. At a temperature of 600 degrees Celsius, the process of intensive scale formation begins. Because 12Kh1MF is weldable to a limited extent, thorough preliminary heating is recommended and only then proper heat treatment. The density at 20 degrees Celsius is approximately 7.8×10? kg / m ?. This brand is supplied in both heat-treated and non-processed condition.

    The described characteristics of this type of steel make it possible to use it for the manufacture of pipe and steam pipelines that make up steam superheaters, gas turbines and high-pressure collectors. Parts of pipeline installations and pipeline fittings are manufactured with air or oil quenching and air tempering. And also for other parts that require well-coordinated and trouble-free operation at high temperatures (570-585 degrees) or loads: nozzles, bottoms, rings, collar flanges, fittings, tees, as well as rectangular parts of thermal power plants, pipelines or power equipment absolute pressure in which, above 3.9 MPa.

    The weldability of this brand ranges from easy to difficult to weld:

    · & nbsp; welding without restrictions does not require any preliminary or subsequent heat treatment;

    · & nbsp; limited weldable steel needs to be heated before welding up to 100-120 degrees Celsius and additional processing after welding;

    · & nbsp; when welding difficult-to-weld steel, it is necessary to warm up the elements to 200-300 degrees, and only after that start welding. After that, it is recommended to anneal to obtain a higher quality welds.

    Type 12X1MF – heat-resistant and low-alloyed, contains average values ​​of carbon (0.12%) and alloying chemical elements: chromium (1%), vanadium and molybdenum (0.3% each). Designed to create heat-resistant parts and structures. After reviewing our prices, you can purchase steel 12H1MF / 12HMF and various products from it: pipes, circles, sheets.

    Buy stainless steel pipe 12Х1МФ 32х4.5 mm seamless thick-walled from warehouse ➤ Kiev, Dnepropetrovsk (Ukraine) ⭐ Boiler pipe 12Х1МФ 32х4.5 mm seamless thick-walled⚡

    Boiler pipes & nbsp; are seamless steel pipes with a diameter of 57 – 426 mm, used in superheaters, steam pipelines and collectors of boiler installations with high and supercritical parameters of steam power plants. < / p>

    The production of boiler pipes is regulated by TU 14-3-460-75. Pipes are made from rolled, forged, stripped, drilled or non-drilled billets of carbon, alloyed and high-alloy steel grades (20, 15GS, 15HM, 12H1MF, 15H1M1F, 12H2MFSR, 12H11V2MF, 12H18H12T). Pipes are produced in measured and unmeasured lengths.

    According to the method of production, pipes are divided into hot-, cold- and heat-deformed. Cold-deformed pipes of this category are produced by cold rolling from pipe billets produced by metallurgical enterprises.acceptance, or from hot-pressed conversion pipes. For the production of hot-formed boiler tubes with a diameter of 42 to 219 mm, hot pressing technology is used.

    Boiler pipes in comparison with pipes of general purpose are technologically more complex product. Higher requirements are imposed on the quality of the inner surface of pipes of this category, including the height of the inner burr – it must be rolled out or removed in another way. In addition, pipes are subject to heat treatment without fail.
