Material Description
1.2316 is normally supplied quenched and tempered (+QT), typically around 30 HRC. Although it is a corrosion-resistant stainless steel, its machining behaviour is strongly influenced by its relatively high strength, so it is usually better to approach it like a conventional steel of similar strength while using a somewhat lower cutting speed due to its lower thermal conductivity. Universal tools and geometries that cover both medium-strength and higher-strength steels are usually the best choice. Sharp stainless-steel geometries can still work, while stronger grades and geometries for pre-hardened steels can be used where higher tool life and edge stability are required.
