S15CBD

Low Carbon Steel

The surface is bright and smooth after cold drawing. The main difference with S15C is that the surface can be roughed without turning. That can be directly used for milling or grinding, which greatly reduces the processing time. its characteristics and application are same as S15C.

Low mechanical strength, good plasticity and toughness, easy molding under cold conditions, good workability under forging or standardization conditions, it is also easy cutting and good welding performance. Carburizing and cyanidation can be carried out to increase the surface hardness.

Application in the manufacture of low-strength welded parts, cold stampings, forgings and carburized parts such as bolts, washers, partitions, clutch parts, bearing parts, safety buckles, etc.
