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.
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.
