Vinnitsa sheet, circle tool steel U8A, HVG, 9XC, 5HNM, R6M5, spring-loaded 65G

The main methods of manufacturing round steel:
 • hot rolling according to 2590-88 standard.
The process is the same as in metal forming, namely: steel processing is carried out on a special rolling mill with rotating rolls having different diameters. Before this, the workpiece is heated to the recrystallization temperature and moves along the line. The desired shape is achieved through the influence of rotating rolls, which lengthen the workpiece step by step; form the required circular cross section. Hot rolled steel has excellent performance and can be used to produce profiles with a cross section of 5-270 mm.
• Cold rolled products (calibration). Production in accordance with GOST 7417-75.
The main distinguishing feature from the first method is that there is no heating of the feedstock to high temperature indicators. Produce bars, distance from 3 to 100 mm. The advantage of this method is a higher level of accuracy of geometric parameters, higher performance during operation. • Forged bar
Automated forging is used; all indicators according to Standard 1133-71. Products distance 40-200 mm, then subjected to further processing.
Types of metal used:
• structural and low-alloyed metal (grades 08,20,10, 09G2, 15KhSND and others).
• structural carbon and alloy steel - St3Gps, E360, S185, S275JR, 20, 30, 35, 60, 80, 09G2S, 60S2, 65G, S45, 30MnB5, C15C, E295, 11SMnPb30, 10S20, st 40X and others; • Carbon raw materials of standard quality (St1kp, St1sp, and others)
• Alloy tool steels - U7, U10, U12A, C70U, C90U, C120U, 9KhVG, Kh12F1, 5KhV2S, Kh12, 102Cr6, 21MnCr5, 35CrMo7, etc.;
• Structural spring-spring quality steel (60G, 60S2 and others).
• High speed alloyed steels – Р6М5, Р18, Р9, Р6М5К5 and HS2-9-1-8; heat-resistant and heat-resistant steels - 12Kh8VF and X6CrNiMoB17-12-2; bearing steels - ШХ15, ШХ20СГ, ШХ4-Ш, X82WMoCrV6-5-4 and X47Cr14. Spring steels are a special type of steel designed for the production of a variety of elastic parts, among which springs and springs are the most popular. The main difference of this type of steel is a much increased yield strength. According to the method of subsequent processing and the final product, the steel can be supplied in sheets, wire, hexagons, squares.
Any spring steel is necessarily subjected to thermomechanical treatment. It increases strength and wear resistance by 2 times.
