Carbon Steel copper plated weld stud with Heat Treatment.
Welding studs refers to the method of welding metal studs or other similar metal parts (bolts, nails, etc.) to the workpiece (usually plate) is called stud welding, and the stud used for welding here is called welding Studs.
General heat treatment requirements
The mechanical properties of bolts with mechanical properties of 8.8 and higher and M16 type nuts) generally have to be quenched and tempered to meet the requirements of mechanical properties.
According to the thread accuracy, hardness, processing route and user's specific requirements of the bolt and the mother, or the heat treatment of the finished product or the heat treatment of the semi-finished product. The decarburization layer on the surface of the raw material has been basically removed during the processing of the bolted nut. It can be thermally quenched in the salt furnace and mesh belt furnace with good deoxidation. Tooth tip, although it is heated in a salt bath furnace with good deoxidation or in a generally protected protective gas neon, or in a controllable gas neon furnace that can strictly control the carbon potential, it can be heated at the same time to decarburize the surface. Moderate recarburization to ensure that the decarburization layer is within the acceptable range.
Selection of quenching medium The selection of quenching medium should first ensure sufficient cooling capacity. The hardenability of steel for cold piers is generally lower than that of non-cold steel of the same grade. Therefore, the cooling capacity of quenching medium should be selected at a high point. , Distortion and cracking should also be considered. Carbon steel with a carbon content of more than 0.49% (mass fraction) has a strict tendency to crack, especially for quenching media.
