Stainless steel milling and turning parts
Stainless steel is a high-alloy steel with a chromium content of more than 10.5%, which provides very good corrosion resistance and good mechanical properties. Turning and milling parts made of stainless steel are used in a wide variety of applications, from medical technology to the chemical and pharmaceutical industries to mechanical and plant engineering.
We offer you nine different stainless steel alloys to choose from, which differ significantly in terms of their mechanical properties and machinability. Our overview will help you select the ideal material for your turning and milling parts.
Surface treatments for stainless steel turning and milling parts
Martensitic steels can be hardened. Austenitic steels can be nitrided. In addition, many other Surface and heat treatment processes to choose from.
