Stainless Steel Alloy 416 HT is a free-machining stainless steel with a machinability of 85%; the highest of all stainless steels. As with most of the free-machining stainless steels, machinability can be improved with the addition of Sulphur, which leads to the formation of manganese sulphide inclusions. The addition of Sulphur also reduces formability, weldability and corrosion resistance of the 416 grades to below grade 410. Due to their high machinability and relatively low cost, type 416 are sold in highly tempered, hardened or unhardened forms.
