Bearing steel is a steel used to manufacture balls, rollers, and bearing rings. Bearing steel has high and uniform hardness, wear resistance, and high elastic limit. Strict requirements are placed on the uniformity of chemical composition, content and distribution of non-metallic inclusions, and distribution of carbides in bearing steel, making it one of the most stringent steel grades in all steel production. In 1976, the International Organization for Standardization (ISO) incorporated some commonly used bearing steel grades into international standards, d
Alloy steel contains more other elements compared to carbon steel Alloy steel refers to steel that contains not only silicon and manganese as alloying elements or deoxidizing elements, but also other alloying elements, some of which also contain certain non-metallic elements. According to the content of alloying elements in steel, it can be further divided into low alloy steel, medium alloy steel, and high alloy steel. Carbon steel mainly refers to steel whose mechanical
alloy steel Alloy steel is made by adding other alloying elements in addition to iron and carbon. A ferrocarbon alloy formed by adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel. By adding different elements and adopting appropr
Why is steel bar cold drawn? Cold worked steel bars. At room temperature, cold drawing or cold drawing of steel bars can increase their yield point, thereby increasing their strength and achieving the goal of saving steel. After cold processing, steel bars can be saved
why is cold drawn steel stronger?
Cold draw steel Cold drawing is the process of forcibly drawing round steel bars through a hard alloy drawing die hole. The effect of cold drawing is stronger than that of pure tension, and the steel bars are not only subjected to tension, but also to co
