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.
Mill certificates with your order
Mill certifications are included. Open or download certificates for your assigned material from My Orders once available. Specify DFARS or Domestic when your order requires it.

Annealed 316/316L for chloride service
Stock is solution-annealed round bar certified to ASTM A276 and A479, marked 316L on every certificate we have supplied. The molybdenum addition is what resists pitting in salt water, brine and many acids where 304 will not.
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. 316 work-hardens slightly faster than 304, so keep tools sharp and feeds steady.
