416 Stainless Steel Bars Manufacturer
What are 416 Stainless Steel Bars?
416 stainless steel bars are martensitic, chromium-based stainless steel bars modified with added sulfur for enhanced machinability. With the highest machinability of all stainless grades, SS 416 is primarily used for automatic screw machines, fasteners, gears, shafts, and valve components—especially where high strength and corrosion resistance are needed after machining and heat treatment.
