13H11N2V2MF Tube circle
Steel brand 13H11N2V2MF (EI961-sh) refers to one of the most common in the metal market. It is widely used in engineering as a pipe. This tube is capable of withstanding a temperature of 1000 degrees in high temperature installations. 11% chromium in the alloy provides excellent resistance to oxidation. Besides chromium composition of about 2% nickel, and tungsten, up to 1% additives of molybdenum and vanadium, and carbon hundredths of a percent (013%), phosphorus and sulfur. Due to the fact that the theory of heat-resistant alloying and heat-resistant steel based on the influence of various substances on the basis of chromium and nickel, such as steel has a different name — chromium-nickel alloy. It includes carbon in its composition in a limited amount. Increased carbon content of more than 0.2% deteriorates the heat resistance due to the formation of chromium carbides.

This mark is melted in an open arc furnace. Unfetters product at an initial temperature of 1180 degrees and 900 degrees for the completion of processing. After performing deformation steel is usually cools down outdoors. Also, in addition to air cooling or oil cooling is provided by means of water, followed by aging products for 4−5 hours. The tube can produce a seamless manner — a seamless tubes. A method of use of welding. Pipes, electric-type svariayutsya by means of electrodes CT-19.
Pipes vary in relation to the diameter of the wall thickness. With a thickness of about 0.3−6 mm Ø 5−250 mm pipes are called extra thin-walled. A thin-walled tube has a thickness of 0,6−20 mm and the same diameter. Thick-walled tube has a wall thickness of 1,6−24 mm and Ø 6−250 mm. Especially pipes made from thick-wall thickness 2.12 mm, Ø 6−70 mm.
pipe production technology and range 13H11N2V2MF like. Of these parts are made of the working mechanisms operating at high temperatures of ~ 1000 ° C, heat-resistant pieces of industrial designs. Circles of alloy hot-rolled produced 13H11N2V2MF way diameter of 5−270 mm. If necessary, the plants go beyond this standard in the interests of the customer. As standard, the roundness of the circle can not be more than 50% of the limit deviation of a circular diameter.
