THE ART OF MACHINING STAINLESS STEEL Austenitic and duplex stainless steels have certain properties that makes them difficult to machine compared to carbon steels or ferritic and martensitic stainless steels. The greatest difference is the high ductility of austenitic and duplex stainless steels, as well as their tendency to work harden and form built-up edges on the cutting tool. Moreover, in duplex materials, chip forming becomes more difficult due to the high strength of these materials. In Sanmac® materials, machinability has been improved without jeopardising properties such as...
