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

Hot-rolled steel from ordinary quality steel GOST 535-88 is produced by rolling on the rolling condition from ordinary quality steel with a high carbon content.

    Rolled carbon structural steel in accordance with GOST 1050-88, the range of which consists of hot-rolled and forged round products made of high-quality carbon structural steel.
    Hot-rolled and forged round steel made of spring-loaded carbon and alloy steel GOST 14959-79 with a diameter or thickness up to 250 mm, as well as round rolled products with special surface treatment, intended for the manufacture of springs, springs and other parts of machines and mechanisms used in the hardened and tempered state.
Round bars made of alloyed structural steel GOST 4543-71, forged and hot-rolled, thickness or diameter up to 250 mm, calibrated and with special surface treatment of alloyed structural steel, used in a heat-treated state. High-strength rolled steel GOST 19281-89, used for riveted, bolted and welded structures, is mainly used in products without additional heat treatment. This GOST also applies to ingots, slabs, forgings and stampings, thin sheets and blooms in terms of chemical composition standards. Rolled products from high-quality structural carbon and alloy steel GOST 10702-78, calibrated and with special surface treatment, used for the manufacture of products by upsetting and cold extrusion, as well as for hot-rolled round steel (rolled wire, wire rod) for the manufacture of calibrated rolled products and wire from a special finish surfaces.

Round steel is used for the manufacture of bolts, studs, fasteners, shafts in units, springs, and for other purposes in construction and industry. The properties of round bars depend on the metal from which they are made, the method of manufacture, purpose and final processing.
