Special steels are high-alloy steels and alloys according to GOST 5632, characterized by high corrosion resistance and an increased temperature limit.

Sheet steel for special purposes is a widely used material in mechanical engineering, construction and economic activities. Due to its high chemical resistance and purity, food-grade special steel is in demand in the food industry. These steels have earned their name due to the presence of certain chemical, physical and mechanical properties, which are provided by special alloying impurities and technological processing.

According to the production method, the circles are made hot-rolled and cold-rolled.

Hot-rolled steel circle GOST 2590-88 is produced by hot rolling. The surface of the hot-rolled wheel can be ground. And also the circles are forged - forged steel round and square according to GOST 1133-71. Hot-rolled and forged metal circles, depending on the purpose, are subjected to heat treatment. Cold-rolled or cold-drawn circle - calibrated rolled products, more accurate in diameter, manufactured in accordance with GOST 7417-75, with a diameter of 3 to 100 mm, smelted in a special way, and also processed by cold drawing. As a result of such manufacturing, the physical, plastic, mechanical properties of steel, surface characteristics increase.

Additional processing gives a polished or matte surface. Circle calibrated steel in accordance with GOST 7417 can be made of stainless steel, the surface of which is polished to improve the properties of steel. A stainless product has the first class of the degree of curvature and the second. Also, a round steel bar can be subjected to additional galvanizing to ensure resistance to aggressive environments and obtain a galvanized steel circle.

Application of steel circle

Steel circles are often used as blanks for metal products: shaped bars and tubular products. Hot-rolled steel circle is universal, it is used for reinforcing reinforced concrete products as an alternative to class a1 (A240) reinforcement, in construction, in mechanical engineering, shipbuilding and machine tool building, heavy industry, automotive industry, space industry, for the construction and strengthening of road barriers, various metal structures. Various types of fasteners for the needs of the railway are made from hot-rolled circle: washers, spring terminals, etc. The calibrated circle, due to its resistance to adverse conditions, has become indispensable in construction in northern latitudes, and it is also used for grounding gas pipeline lines. Calibrated circles are widely used in design and outdoor advertising. Stainless steel circles are used in construction, often for those structures that will be subjected to aggressive conditions - increased loads and high temperatures. Stainless calibrated wheels have found their place in the automotive, aviation, shipbuilding, pharmaceutical, food and other industries, in the production of pipes and the manufacture of grinding balls.
