The use of bearing steel
Buy in any assortment of brands and profiles of bearing steel at economically favorable prices from the manufacturers offers the company Electrovek-steel. The supplier ensures timely delivery of products to any point specified by the customer.
Features of the properties of bearing steels and requirements
In accordance with its technological purpose, domestic grades of bearing steel are produced by hot rolling technology. The range of rolled steel of such steels includes:
Round and square cross bars;
Hot rolled strip;
Cold and hot rolling tubes;
Forgings previously deposited on forging hammers;
Single and multiple cold drawing (for wire).
All technical standards and requirements that relate to the quality parameters of rolled bearings of bearing steels, as well as the method for controlling the basic physical and mechanical properties are given in GOST 801−68 (sheet and long products), in GOST 800−78 (tube rolling), in GOST 4727−67 (wire). Since the bearing grade SHX15SHD belongs to the category of bearing steel by vacuum-arc remelting, its properties are specified in GOST 21022−75.
At the enterprises engaged in the production of such products, the properties of bearing steels are also controlled by a number of departmental specifications. Particularly careful quality control of bearing steel passes through the following parameters: continuity over the section, absence of foils, sunsets, surface and deep cracks.
To buy domestic bearing steels, the parameters of which correspond to the standards of GOST 801−78, at economically affordable prices, Electrovek-Steel offers. The supplier guarantees timely delivery of the purchased rolled metal to the address specified by the customer.
Areas of use
Bearing steel is used in the vast majority of technical devices and mechanisms — production and handling equipment, vehicles, power equipment, as well as in instrument engineering. Typical parts that are produced from bearing steels type SHKh4… SHKh9 are all ball and roller bearings (rings, balls, rollers) and other parts operated at elevated pressures and requiring high hardness, resistance to wear and abrasion. So, from the bearing steels ШХ15 and ШХ15СГ, the pushers of the engine valves, punch and die of cold stamping die and other products are produced, the durability of which is determined by the increased contact strength.
Bearing steels are subject to very stringent requirements regarding the microstructure, the presence and nature of non-metallic inclusions, the hardness and depth of the thermally altered layers. Hot-rolling steel is used in the manufacture of bearing rings, while cold-rolled steel is used to manufacture balls and rollers, as well as a die tool.
Company Electrovek-steel offers to purchase at a reasonable price of the manufacturer a diverse range of bearing steels. The supplier guarantees prompt delivery of products to the address specified by the customer.
