Wear -resistant steel is one of the key materials used in engineering, construction, mining and processing industry — https://neva-stel.ru/. Its main advantage is the ability to withstand high loads and prolonged exposure to the abrasive environment. These qualities make wear -resistant steel indispensable when designing nodes, where wear is the main factor in destruction.
Firmness — the basis of resistance to wear
One of the most important parameters of wear -resistant steel is hardness. It is determined by the Brinell or Vickers scale and can vary from 300 to 600 HB, depending on the brand. The higher the hardness, the better the material resists abrasion and mechanical destruction. However, excessive hardness can negatively affect fragility, so it is important to observe the balance.
Strength and fluidity limit
In the selection of material, the engineer is important to take into account the strength of the strength and the limit of fluidity. Basy -resistant steel should not only “not erase”, but also withstand the loads, blows and vibrations. Typical values of the strength limit — from 1000 MPa and above. Some brands (for example, Hardox 450) provide high strength while maintaining sufficient plasticity.
Shock viscosity
An equally significant indicator is shock viscosity. This is the ability of the material to withstand destruction during shock loads. In the production of crushing and career equipment, steels are often used that can maintain their characteristics even at low temperatures. Such viscosity is especially important for operation in harsh climatic conditions.
Wear in different environments
Wear resistance can manifest itself differently depending on the conditions: abrasive wear, adhesion, corrosion-mechanical. When choosing a brand, the engineer should take into account the type of environment to work with the material. For example, in the presence of water and sand, it is important to consider not only hardness, but also resistance to corrosion.
Conclusion
Understanding the mechanical properties of wear -resistant steel helps engineers correctly select the material for a specific task. It is important to consider not only nominal indicators of strength and hardness, but also features of operation — temperature regimes, dynamic loads, abrasive and chemical environment. Only an integrated approach will ensure the reliability and durability of the structure.
