The bars are precision drawn to ASTM half standard or ISO H9 tolerances and can help fabricators and machine shops maximize their productivity. PROJECT 70+ PDB stainless attributes include chamfered ends, improved straightness and tighter OD tolerances for consistent size along the entire length of the bar and minimal ‘out of round’ condition.

"This latest offering from Carpenter demonstrates our continued commitment to the machining market," said Carol R Jackson, Carpenter’s vice president – bar, wire, strip and plate products. "Customers who ran PROJECT 70+ PDB bar during our trial phase reported greater reliability and productivity through their CNC Swiss-style screw machines."

Carpenter currently offers PROJECT 70+ PDB stainless in round bar product forms packaged directly from the finishing line in customer-friendly boxed quantities to preserve straightness. PROJECT 70+ PDB stainless will initially be sold in seven nominal diameters from 0.2500" to 0.6250" with 144" standard lengths.
