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. However, in any case, the standards require that the products be protected with oil from corrosion. An exception is made only for a stainless steel circle; oil can also be dispensed with by agreement with the customer.

Features of production and delivery

You can buy a calibrated circle of various sizes made of steel of various grades. The diameter varies from 3 to 270 mm and more. With a size of up to 5 mm (and with the agreement of the customer - up to 25 and even more), the circle can be supplied in coils. If the diameter exceeds this figure, then it is customary to manufacture rolled products in rods of measured and non-measured length.

The rods are supplied bundled, each bundle must be marked. In particular, the diameter of the rod, steel grade, type of manufacturing accuracy (high, increased, normal accuracy) are indicated.

The length of the rods can be from 1.5 to 6.5 m depending on the type of steel. If necessary, you can buy a calibrated circle cut into pieces of the required length. It is worth remembering that the state standard assumes the absence of burrs and bends. A calibrated steel circle is made by cold rolling or drawing. It is used to turn various parts on lathes from this round blank. Various tools are made of steel: screwdrivers, wrenches and adjustable wrenches. Rods are made from one and a half to six and a half meters long and from three to two hundred and seventy millimeters in diameter. If the diameter of the circle is up to five millimeters, it is packed in coils. Circles with bends and burrs are not allowed in production. The surface must be smooth. The circles must be even and of the same length. When working with circles, protect your eyes with special glasses and your hands with protective gloves. This material is easy to process. It can be sawed, drilled and welded. The circles are packed in coils of several pieces, of the same length. Steel is a very strong and durable material. Products made of this metal will serve you for many years. The circle is called calibrated because it is very accurately measured in length and diameter. Higher requirements for accuracy are imposed on them in comparison with ordinary circles. Some circles are additionally polished in order to obtain a mirror surface. The surface of the circles is coated with oil to protect against corrosion. In mechanical engineering, the railway industry and shipbuilding, a large number of different parts are made of steel. The price of circles depends on the grade of steel from which they are made, the presence or absence of a mirror polished surface and the amount of impurities in the steel itself. Circles are used in construction and at home as supports for fences and railings. The quality of the surface of the circles is divided into three types of accuracy. A - medium, B - high and B - an increased level of accuracy of the surface of the circle. In the diameter of future circles, minor deviations are allowed within the range from zero point one to zero point three tenths of a millimeter. You should buy steel circles only from trusted manufacturers to avoid low-quality and defective goods.
