16MnCrS5 is a grade with improved machinability. It is recommended for applications with high demands on mechanical properties, machinability and surface quality. It is also suitable for case hardening and has good weldability.
For additional Heat Treatment Data, please visit the Heat Treatment Guide.
The basis for the concept is that non-metallic inclusions are modified and controlled with calcium treatment in a way to minimize tool wear and to maximize chip control in machining operations.
Our M-Steel treatment can be applied to any steel grade.
