High Speed Steel M35
Din 1.3243 is cobalt content material in these high-performance excessive-speed steel results in high pink hardness and tempering resistance. As a final result, this grade is primarily suitable for conditions involving thermal stresses and discontinuous cutting. This grade is typically used as heavy-duty milling cutters of every kind, particularly stressed twist drills and taps, profile knives, machining of high-strength substances, broaches.
