1215 free-cutting steel is an environmentally friendly material. Compared with 12L14, it does not contain lead and environmentally harmful substances. It has good machinability and is suitable for general electroplating shafts, cutting materials and general parts. Due to its accurate precision and good surface condition, 1215 free-cutting steel products can be used directly, such as spraying, sandblasting, bending, drilling, and can also be directly electroplated after fine drawing according to actual requirements, eliminating a lot of machining time and saving the cost of configuring processing machinery.

It is mainly used to make instruments, watch parts, automobiles, machine tools and other machines that are subjected to small forces but have strict requirements on size and finish.
