Application Summary AI generated
GB/T 8731-2008 specifies the technical requirements, dimensions, and testing methods for free-cutting structural steel, which is designed to improve machinability by containing elements like sulfur or lead. It is primarily applied in the manufacturing of precision mechanical components, such as screws, nuts, and shafts, where high-speed automated machining is required. This standard ensures consistent material properties for use in industries like automotive, electronics, and general engineering.
