15H12N2MVFAB co-Tube circle
Alloy brand 15H12N2MVFAB-w (EP517-sh)) is one of the most common in the metal market. In this steel has a foreign counterpart. Mark 15H12N2MVFAB co-relates to a heat-resistant high alloys, is composed of about 12% chromium. This provides excellent resistance to oxidation. Besides chromium composition of about 2% nickel, 1% additive of molybdenum, tungsten, niobium and vanadium, and carbon hundredths of a percent (015%), phosphorus and sulfur. Since the theory of alloying heat-resistant and heat-resistant steels is based on the influence of various substances on the basis of chromium and nickel, this steel is called chromium-nickel alloy. Steel-15H12N2MVFAB dd 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.

The most popular product is a tube that can withstand temperatures of over 1000 degrees in the high setting. -e 12% chromium content in the composition ensures high resistance to oxidative process. Circles and tubes brand 15H12N2MVFAB-door in demand in various fields of industry as a blank for the manufacture of parts and working mechanisms of mobile fastenings.
Mark 15H12N2MVFAB co-smelted in open arc furnaces. Unfetters items with a starting temperature of about 1180 degrees, and 900 degrees at the end of the treatment process. After deformation of the product is typically cooled in air. It is also possible in the cooling water or oil, followed by aging the product. Roundness range should not exceed 50% of the amount of deviation at the diameter of the pipes vary in the ratio of wall thickness to diameter. 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-walled, 2.12 mm thick, Ø 6−70 mm. Welding is performed by the CT-type electrode 19.
