SUM24L easy cutting structural steel is a Japanese standard. SUM24L easy cutting structural steel, also known as automatic machine tool processing steel or simply automatic steel, is a type of steel that is easily cut and processed by processes such as turning, milling, pulling, planing, drilling, etc. It was developed to adapt to the automation of mechanical processing and production on assembly lines. This type of steel can be machined with higher cutting speeds and deeper cutting depths. Additionally, the addition of easy to cut elements to the steel reduces cutting resistance, and the properties of the added elements and the resulting compounds lubricate the tool edges, making chips more prone to breakage and reducing wear. This improves the smoothness and accuracy of the machined parts, enhances tool life, and improves production efficiency.
SUM24L Free Cutting Steel Chemical Composition:
Carbon C:<=0.15
Manganese Mn: 0.85-1.15
Sulfur S: 0.26-0.35
Phosphorus P: 0.04~0.09
Lead Pb: 0.10~0.35
SUM24L Free Cutting Steel Usage:
Mainly used for the production of instruments, watch parts, automobiles, machine tools, and other various machines with strict requirements for size and smoothness due to low stress. Standard parts with strict requirements for size accuracy and smoothness but relatively low requirements for mechanical performance, such as gears, shafts, bolts, valves, bushings, pins, pipe joints, spring seat cushions, machine tool screws, plastic molding molds, surgical and dental procedures, etc., require secondary processing and cutting. These products have good cutting performance and are commonly used as cutting materials for information, precision, communication, and 3C household appliances.
