Alloy steel bar refers to a kind of alloy steel with a section similar to a circle. Alloy steel bars are widely used in military, automobile, aviation, shipping, railway, nuclear power and other industries, and can also be processed into various metal products, such as spring wire, communication wire, various nails, etc.
Alloy steel bars can be divided into bearing steel, gear steel, alloy spring steel, alloy tube billet steel, etc. according to their applications. Because different fields have different requirements on the characteristics and size of alloy steel, alloy steel bars used in different fields will be different. For example, bearing steel is one of the more important subdivision products of alloy steel bars. It is mainly used to produce bearings. It needs to bear great pressure and friction, and has high requirements on hardness, wear resistance and elastic limit.
