بیشترMechanical Properties. CF8M and CF8 stainless steels also have different mechanical properties. CF8M has a higher yield strength and tensile strength than CF8, meaning it is better suited for applications that require high strength. However, CF8 has better ductility than CF8M, which is more resistant to cracking during welding.
