On the basis of increasing the content of silicon and manganese in GCr15 steel, its hardenability, elastic limit and wear resistance are significantly improved, cold processing deformation medium, slightly poor machinability, poor weldability, more sensitive to the formation of white spots, there is a tendency of temper brittleness. It is used for manufacturing large-size bearing rings, steel balls, tapered rollers, cylindrical rollers, spherical rollers, etc. The working temperature of bearing parts is less than 180°C. It is also used for manufacturing molds, measuring tools, taps and other parts requiring high hardness and wear resistance

1. Physical properties of materials Including specific gravity, melting point, electrical conductivity, thermal conductivity and expansibility. Different uses of the workpiece, the physical properties of metal materials are not the same requirements.
2. The chemical properties of materials mainly refer to the ability of metal materials to resist the corrosion of active media under constant temperature or high temperature conditions. 3.The technological performance of materials is the synthesis of physical and chemical properties of metal materials, and the ability to process and form easily. According to different technological methods, the technological properties mainly include casting properties, forging properties, weldability and machining properties. The technological properties of materials should be considered when designing parts and selecting processing methods.
