Unveiling the Technical Properties and Advantages of CF9SMn28 Steel Grade

CF9SMn28 is a low carbon non-alloyed free-cutting steel grade that is widely used in various industries due to its excellent mechanical properties and chemical composition.

The chemical composition of CF9SMn28 steel grade is as follows:

Carbon (C): 0.07-0.15%
Silicon (Si): 0.10-0.50%
Manganese (Mn): 1.00-1.40%
Phosphorus (P): max 0.040%
Sulfur (S): max 0.20%
Chromium (Cr): max 0.35%
Copper (Cu): max 0.30%

The low carbon content of CF9SMn28 steel grade provides excellent machinability and makes it suitable for high-speed machining operations. It also offers good weldability, allowing for easy fabrication of components.

The mechanical properties of CF9SMn28 steel grade are as follows:

Tensile strength: 520-680 MPa
Yield strength: 400-560 MPa
