11SMnPb30 German standard implementation standard DIN EN 10087-1999 Hot-rolled bar and wire delivery technical conditions, 11SMnPb30 is a free-cutting structural steel, which is easy to be cut by (turning, milling, drawing, planing, drilling, etc.), also known as Steel for automatic machine tool processing, referred to as automatic steel. It is produced to adapt to mechanical processing automation and assembly line production. This type of steel can be cut with a higher cutting speed and a deeper cutting amount, and the cutting resistance is reduced due to the easy-cutting elements added to the steel, and the cutting edge is lubricated due to the characteristics of the added element itself and the compound formed. The role of the part makes the chips easy to break and reduces wear, thereby improving the finish and precision of the processed parts, and improving the tool life and production efficiency.
