DIN 44Mn28 Free Cutting Steel
Free cutting steel is a type of steel that is specifically designed to be easily machined or cut, making it ideal for applications where high productivity and efficiency are required. This type of steel typically contains higher levels of sulfur, lead, or other elements that help improve its machinability.
Free cutting steel is commonly used in the manufacturing of various components and parts, such as bolts, screws, gears, and shafts. Its excellent machinability allows for faster cutting speeds, reduced tool wear, and improved surface finish, resulting in cost savings and increased productivity.

DIN 44Mn28 Free Cutting Steel
1: DIN 44Mn28 steel introduction
ASTM1141 is high sulfur medium carbon free-cutting steel, which has better cutting performance. Compared with 45# steel, ASTM1141 can increase tool life by four times, increase productivity by 30%, and has higher strength and hardness.
