DIN 1651 Grade 9SMn28 untreated
DIN 1651 Grade 9SMn28 untreated introduction
Balanced machining steel 9 SMn 28 is the standard grade for all mass turning tools and should be the substitution of the 9 S 20. The steel is suited for thin walled parts and little cold forming.
Application: automotive engineering, toolbuilding, apparatus engineering
