Saw cuts and machining allowance
Our standard saw-cut tolerance is +1/8″ / −0″ on cut length. Allow material for facing and finish machining. A different tolerance agreed on your order takes precedence.
Diameter and straightness follow the supplied mill or producer specification. Full mill-stock pieces ship uncut and retain mill tolerances.

Annealed free-machining 416
Stock is annealed, peeled or ground round bar certified to ASTM A582. The sulfur addition that makes 416 the easiest stainless to machine also limits its corrosion resistance and weldability, so it belongs on turned parts, shafts and fasteners rather than wet or welded service.
Plain and DFARS-melt bar are separate stock lines; pick DFARS above when the drawing requires qualifying-country melt.
Planning the finished dimensions
Random-length bar is cut to your length with square ends; allow for facing and finish turning. 416 can be hardened and tempered after machining if the drawing calls for it.
