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, dual-certified 304/304L
Stock is cold-finished or peeled round bar in the solution-annealed condition, certified to ASTM A276 and A479 and dual-marked 304/304L on every certificate we have supplied. Bar is sold by diameter; 304 is not hardenable by heat treatment.
Sizes come from vendor stock in Troy, Michigan. Plain and DFARS-melt bar are separate stock lines, so 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 for turning the diameter to finish. 304 work-hardens quickly, so plan steady feeds and rigid workholding.
