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.

Product Description

DIN 44Mn28 Free Cutting Steel 

DIN 44Mn28 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.

4: DIN 44Mn28 steel mechanical properties

    The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.
