13KH11N2V2MF - эи961 wire, round
Steel brand 13KH11N2V2MF (ЕИ961-W) is one of the most common in the metal market. It is widely used in engineering in the form of pipes. Such a tube can withstand temperatures over 1000 degrees in high temperature installations. 11% chromium in the alloy provides excellent resistance to oxidation. In addition to chromium of about 2% Nickel, and tungsten additives to 1% molybdenum and vanadium, as well as hundredths of a percent carbon (013%), phosphorus and sulfur. Due to the fact that the theory of alloying of heat-resistant steels is based on the effects of various substances on the basis of chromium and Nickel, such steel also has another name — chromium-Nickel alloy. It provides in its composition of carbon in a limited quantity. Increased carbon content exceeding 0.2% deteriorates the heat resistance due to the formation of chromium carbides.
Percentage composition GOST 5632−72
This brand is smelted in an open arc furnace. Rusk products at an initial temperature, 1180 degrees and 900 degrees at the end of the treatment process. After carried out the deformation of the steel is usually cold outdoors. Also, in addition to cooling in air or in oil, provides for cooling with water, followed by aging products for 4−5 hours. Pipe can produce seamless way seamless pipes. And use the welding method. Pipe welded type warialda with electrodes CT-19.
The pipes vary in ratio of wall thickness to diameter. At a thickness of about 0.3−6 mm and Ø 5−250 mm pipe referred to as extremely thin-walled. Thin-walled tube has a thickness of 0,6−20 mm with the same diameter. Thick-walled pipe has a wall thickness of 1,6−24 mm and Ø 6−250 mm. Particularly thick-walled pipe is made with a wall thickness of 2−12 mm, Ø 6−70 mm.
Technology of production of pipes and round 13KH11N2V2MF similar. Of them parts of the working mechanisms working at high temperatures ~1000°C, heat-resistant fragments of industrial structures. Circles alloy 13KH11N2V2MF produced by hot 5−270 mm. in diameter, If necessary, factories beyond the scope of this standard in the interests of the customer. According to the standard of roundness of the circle can not be more than 50% of the amount of the maximum deviations of the circular diameter.
