Structural steel, the general name of a group of steels intended for the manufacture of building structures and parts of machines or mechanisms. Structural steel used for building structures must have good weldability, and therefore the carbon content in it should not exceed 0.25%; It is subdivided into carbon and low-alloyed (up to 5% alloying elements) of increased strength, and also, depending on the purpose, for bridge building and frames of high-rise buildings. Structural steel used in mechanical engineering, according to its chemical composition, is classified into carbon and alloyed (chromium, chromium-nickel, etc.); according to the manufacturing method - for deformable and foundry; according to the working conditions - for structural, heat-resistant, stainless (corrosion-resistant), wear-resistant. Depending on the carbon content, low-carbon case-hardening steel (0.1-0.25% C) and so-called improved steel (0.25-0.45% C) are distinguished; for some parts (for example, springs, leaf springs), steel with a higher carbon content (0.5-0.65% C) is used. According to the degree of alloying, steel for mechanical engineering is divided into low (up to 5% of alloying elements), medium (5-10%) and high alloy (more than 10%). Machine parts made of steel, as a rule, are subjected to heat treatment. Depending on the value and nature of the loads perceived by the part, requirements are imposed on steel for the required level of strength (Sv can reach 2.5–3 Gn/m2 (250–300 kgf/mm2)), ductility, impact strength, endurance limit, weldability, hardenability and etc. Spring steels combine steel grades with medium or high carbon content with a small amount of alloying components. This type of special steel has a high yield strength. Products made of this metal are capable of restoring their original shape, despite fracture, significant bending, dynamic loads and torsion. Spring steels have a number of features: High flexibility and plasticity. Considerable endurance. Ability to resist brittle fracture. Resistant to stress relief. Such indicators can be achieved by adding alloying components, among which silicon is the main one. Scope of use Spring steels are not intended for welding, as this process proceeds with complications. Metal of this type is used in the manufacture of machine tools and equipment, spring mechanisms and individual elastic elements, springs, washers, as well as knives, bearings and flanges. Sheet spring steel grades are in demand in the production of medical, marine and food equipment, which has high requirements for corrosion resistance. Spring steel is a special type of carbon steel that is used to make springs, leaf springs and other suspension and damping components in various vehicles. It has high strength, wear resistance and durability, thanks to a special processing method that allows it to withstand long cycles of loading and unloading. Spring steel contains carbon in the range from 0.5% to 0.9%, as well as manganese, silicon and phosphorus, which give it unique mechanical properties: High strength - Spring steel has a high strength, making it an ideal material for creating elements that must withstand heavy loads. Durability - spring steel is a durable material that can last for a long time without losing its properties. Corrosion resistance - Spring steel is highly resistant to corrosion, making it an ideal material for use in high humidity and salinity environments. Easily Machinable - Spring steel is easily machined and can be made into a variety of shapes and sizes. High fracture resistance - spring steel is highly resistant to various types of fracture such as corrosion, wear and cracking. Good flexibility - Spring steel has good flexibility, which allows it to take various shapes and bends without losing its properties.
