Brief information about the material
Brief information about the material
Due to its chrome content, both stainless and hot work tools
Steel group. It is suitable for cooling with air and oil as a cooling medium during hardening.
In the stainless steel class, it is in the martensitic stainless steels class due to its hardenability feature. Hardenable stainless steels are the most popular members of their class. Due to its low carbon content, it gets hardness around 45 HRc max. To achieve higher hardness values, it may be necessary to use higher carbon equivalents of the same grade.
