Sell circle with a diameter of from 20 to 220 on steel 45, 20, 35,40 x Structural steel circles ST20, ст35, ст40х, st45 Circles represent constructional steel bars circular profile, obtained by hot rolling of structural steels (ST20, Ст35, Ст40, St45 ) GOST 2590-2006. The hallmark of the construction of a conventional hot rolled steel circles, is that they undergo heat treatment, tempering and other industrial action, which provides community special strength, reliability, flexibility. Therefore, structural circles used in the construction of structures with high strength requirements. Structural circles is a very demanded kind of product. This profile demanded in various sectors of construction and engineering. Circles structural steels are absolutely not interchangeable in the production of various components, structures and mechanisms. They are used as the workpiece in the manufacture of other steel products. The 20 round steel used in the manufacture of parts subjected to moderate loads for long life of case hardening of parts (operation at temperatures above 350° C), thin parts working in abrasion. Round steel 35 ( circle Ст35). Steel 35, and the steel 20 is a structural quality carbon steel. 35 steel is construction and engineering. Ст35 circles as well as circles of St 20 is used in the manufacture of parts designed for exposure to moderate loads, but in the range not higher than 450° C. Such structural circles are used in automobile, Bicycle and mostostroenii, in the sphere of production. In contrast to previous steels (ST20, Ст35) construction circles 45 steel has a high fatigue limit and provide details of improved reliability, durability and resistance to temperature, in the range of 200-600 degrees C.. Circles st45 use in the manufacture of parts and mechanisms, the main requirement which is the maximum wear resistance. 45 steel has excellent performance and reasonable price, but the St 45 is very hard and difficult welding. Circles Ст40. The 40H steel is alloy structural steel, alloy element chromium acts that confirms the "X" in the marking began. Lagerwey items were 40 introduced based on desired characteristics to the steel Circles steel 40KH is used in the manufacture of high strength parts and mechanisms exposed to tearing and compression. And St45 steel 40KH is hard work. If You are interested in the cost of round steel structural , call us and our managers will answer all your questions or see a detailed price list.
