Product Description

ASTM1215 JIS SUM23 Cold Drawn Round Free Cutting Carbon Steel Bar

Introduction of ASTM1215 free steel steel:
1215 free-cutting steel is the addition of sulfur to the steel to make it easy to cut. It is suitable for cutting hot-rolled and cold-drawn steel bars and steel wires for the production of automatic goods. This type of steel can be cut with a higher cutting speed and a larger depth of cut. Due to the free-cutting elements added to the steel, the cutting resistance of the steel is reduced. At the same time, the characteristics of the free-cutting elements and the compounds formed play the role of lubricating cutting tools, easy to break chips, reduce wear, and reduce the surface of the workpiece. Roughness improves tool life and production efficiency.
