Stainless Steel 416
Material Data Sheet
Grade 416 steel is free-machining stainless steel with a machinability of 85%, the highest of all stainless steel. With most of the free-machining stainless steels, the machinability can be improved by adding sulfur, which leads to the formation of manganese sulfide inclusions. The addition of sulfur also reduces the formability, weldability, and corrosion resistance of 416 steels to below that of grade 410. Because of their high machinability and low cost, grade 416 steels are available in highly tempered, hardened, or unhardened forms.
