Detail
Product Description:
1144 free-cutting steel bars are medium carbon steel known for their exceptional machinability. Due to their high manganese content and sulfur inclusions, 1144 steel produces short, manageable chips during machining, reducing processing time and tool wear. This makes them widely used in the manufacture of high-precision mechanical parts such as gears, shafts, and bolts.
1144 free-cutting steel bars are renowned for their excellent cutting performance and high strength, making them particularly suitable for environments that require rapid and efficient machining. The high manganese content and sulfur inclusions in 1144 steel provide exceptional machinability, with short chips forming during cutting that help improve machining efficiency and extend tool life. Additionally, 1144 steel boasts impressive resistance to deformation, maintaining good dimensional stability and surface finish after machining. This makes it an ideal material for manufacturing high-precision parts, especially in applications that demand high strength and wear resistance, such as gears, shafts, bolts, and industrial machinery components. Although its weldability is relatively low, the superior mechanical properties and machinability of 1144 steel compensate for this, making it widely used in automotive manufacturing, mechanical engineering, and heavy equipment production.
