Bearing steel is the solid foundation of mechanical operation. Its extremely high hardness and wear resistance allow it to stand firm in a high-load working environment. Behind every precise rotation, there is the silent persistence of bearing steel. It is a trustworthy "steel guard" in the industrial field.The following content is based on the [...]
Special steels are very important for accurate hardness testing due to their excellent mechanical properties and wide range of applications (such as cutting tools, molds, aerospace components, etc.). When measuring the hardness of parts, everyone is familiar with three commonly used hardness expressions, namely Brinell hardness (HB), Rockwell hardness (HR) and Vickers hardness (HV). [...]
When Industrial Civilization "Stands Up", Its Skeleton is Called 4140 In 1911, the Titanic's steam turbine was made of nickel steel, but it sank due to low-temperature brittleness; In 2023, the landing bracket of the SpaceX starship was made of 4140 steel, successfully withstanding the dual test of 1700℃ high temperature and -180℃ extreme [...]
