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.

Condition A, ready to machine and age
Stock is 17-4 PH (AISI 630, UNS S17400) in Condition A, solution annealed, certified to ASTM A564 with DFARS-compliant melt. Machine the part in this soft condition, then age it: H900 for maximum strength, H1025 for the aerospace balance of strength and toughness, H1150 for maximum toughness.
Every 17-4 bar we stock is DFARS melt, so the DFARS selection above prices the same stock; the plain price applies when no melt requirement exists.
Planning the finished dimensions
Random-length bar is cut to your length with square ends; allow for facing, finish turning and the small dimensional change that comes with aging.
