isi 1215 carbon steel (uns g12150) Cold drawn lead free cutting steel bar-easy machining
11SMn30 AISI 1215 Cold drawn steel bar cold rolld steel bars Free cutting steel
Compared with 12L14 free-cutting steel, 1215 free-cutting steel does not contain lead and does not contain environmentally harmful substances, and has good machinability. Suitable for general plating axis, cutting materials and general parts
The 1215 free cutting steel product has the following advantages:
1. Variety of shape specifications: By designing molds of different shapes, cold-drawn free-cutting steels with different cross-section shapes and different specifications. The angle can be straight or rounded.
2. High precision: Use high quality carbide mold to ensure accurate and uniform tolerances.
3. Smooth surface: The advanced cold extrusion process makes the surface of free-cutting steel products smooth and bright.
4. Material saving: The cold drawing process is to change the shape, specifications and tolerances of the raw materials by cold extrusion, and the loss of raw materials is very small. Compared with the materials consumed by the traditional lathe machining, the free cutting steel saves The material and time are very impressive, especially when the amount of material is large, and the material cost is more significant.
5.Processing time and processing machinery savings: Due to accurate accuracy and good surface condition, free-cutting steel products can be used directly, such as spraying, sanding, bending, drilling, or directly plating after actual polishing. A large amount of machining time and the cost of configuring the processing machinery.
