Zaporozhye circle calibrated steel 6-350 mm st20, st45, 40X, R6M5, 20X13, 08X18H10T (Metallobaza)

A steel circle is a metal-rolled building material, it is a rod with a rounded cross section of different diameters. Manufactured from high quality steel. Rolled metal building material is a rod with a rounded cross-section of different diameters. Manufactured from high quality steel. A metal circle, taking into account rolling accuracy, is classified: On the standard view; calibrated type. rolled metal circle Making a steel circle Various types of steel are used in the production process: low alloyed; alloyed; Highly alloyed; Complexly alloyed. In addition, the steel circle is galvanized, this is done in order for the product to acquire additional positive qualities that are in demand in the grounding system. Circle steel GOST, which 5631 - 61, has a different section: from 5 mm to 270 mm. If the cross section of the product is not more than 9 mm, the circle is sold in coils, round timber of a larger diameter is sold in bars. Application of steel circle Hot-rolled steel circles are in particular demand and are used in many industrial areas. The main area is reinforced concrete structures and industrial production of pipes. Many manufacturing industries use hot rolled bar for the manufacture of steel billets and various parts. Today it is the most popular type of high-quality rolled metal. The price of a circle depends not only on the material and method of manufacture, but also on the accuracy of the product. Given this parameter, allocate: High precision products. This is category "A"; Steel circle with increased accuracy - "B"; Material with standard accuracy - "B". A steel circle is a hot-rolled bar that has a round cross section without a hollow area inside. Steel circles are made of high quality steel, so they are resistant to corrosion, aggressive substances, adverse weather conditions and have a long service life. It is used in construction for reinforcing materials, erecting fences, in the automotive industry for car parts and assemblies, in the space industry, as well as for the production of pipes and technical products: studs, bolts, small balls. Bar material St3. Let's take 10 mm for example. Load 790 kg. Steel grade St3 is intended for the manufacture of hot-rolled steel - bars, shaped, thick sheets, thin sheets, as well as pipes, forgings and stampings, tapes, wires, hardware. GOST 380-2005 Carbon steel of ordinary quality. The letters "St" denote steel, the numbers - the conditional number of the steel grade depending on the chemical composition (0, 1, 2, 3, 4, 5, 6 in total seven), the letter G (if it is present in the marking) - manganese with its mass the share in steel is 0.8% or more, the letters kp, ps, cn - the degree of steel deoxidation, kp - boiling, ps - semi-calm, cn - calm. Steel deoxidation is the process of removing oxygen from liquid steel. GOST 380-2005 does not provide for the designation of steel St3 in the form of "St3" - without the letters "kp", "ps" and "sp". This standard defines the steel grades St3kp, St3ps, St3sp, as well as their modifications with a high manganese content - St3Gsp and St3Gps.
