Circle calibrated - a type of finished steel.For its production uses only the highest quality carbon steel, which is smelted in a special way.For further processing it is used cold drawing.As a result, this approach increases physical, plastic and mechanical properties of steel.Additionally, improved surface characteristics.
Depending on the purpose of the calibrated range of the metal can resist further surface treatment, which results in a polished or matte.In stainless steel products is a first class degree of curvature, and a second class.
calibrated round steel produced an average, increased and high precision processing.For their labeling using the letters A, B and C respectively.
Available range of calibrated according to the standards GOST 7417-75.It is regulated by the production of products, the diameter of the circle which from 3 to 100 mm.Followed up to 5 mm are available, how to plant, in coils.If the diameter is more than 5 mm, the articles have the form of rods.For the calibrated range of permitted tolerances on diameter h11.
manufacturers on request can make a circle with a diameter of 25 mm in the form of coils.In addition, the customer can order a calibrated circle with heat treatment.
calibrated circles in length are divided into:
- product measured length;
- random length products.
For the production of the metal used different grades of steel, for example: 40, 40X, 45, 10, 20, 35. The terms of a calibrated rod length from 2 to 6.5 meters is made from stainless, low-alloy, machine-gun and high-quality carbon steel.High-alloy steel is used for the length of the rods of 1.5 to 6.5 meters.And at random length (not less than 1.5 m) apply quality carbon steel, alloy and machine gun.Calibrated circles of greater length are made by special order.
Circle calibrated found its application in various fields.The steel product is mainly used for reinforcing concrete.Calibrated circle, made of low-alloy steel, because of its resistance to adverse conditions has become indispensable in the northern latitudes during the construction.Also, in some cases, it is used for grounding line of the gas pipeline.Stainless steel rods, ingots of round section (circles calibrated) are used in the automotive, aviation, shipbuilding, wood processing, food and pharmaceutical industries.
also calibrated circles have won a place in the design and outdoor advertising.Furthermore, they are used for internal processing facilities.
Due to the high strength and wear resistance of the calibrated range of stainless steel is suitable for the production of a variety of parts, which will be operated under conditions of high loads and high temperatures.Stainless steel - the perfect material for the manufacture of grinding balls, the production of pipes, construction of various parts and fasteners.
