416
Data verified416 is the free-machining version of 410, with sulfur added so it cuts faster than any other stainless grade. It is the default bar material for high-volume turned parts that still need hardening and mild corrosion resistance.

Applications & Processing
Applications: Valve and pump parts, fasteners, gears, shafts, automatic screw-machine products.
Processing: Best machinability of all stainless steels; welding is impractical because of sulfur; corrosion resistance slightly below 410.
