Product Description
9SMnPb28 Free Cutting Carbon Steel Cold Drawn Round Bar/Rod
Introduction of 9SMnPb28 free steel steel:
9smnpb28 is a free-cutting structural steel. Free-cutting structural steel is abbreviated as free-cutting steel, which contains a small amount of free-cutting elements and has good cutting performance. Free-cutting structural steel is a kind of steel that uses certain elements in steel to improve the cutting performance of steel and is suitable for high-speed cutting on automatic machine tools. Commonly used elements to improve machinability are S, Pb, Ca, etc. Among them, S is the most commonly used. S forms MnS inclusions in steel. MnS is very brittle and has a certain lubricating effect. Therefore, the chips are easy to break, and the surface of the workpiece is smooth. Reduce tool wear and increase cutting speed.
