DUCT-8500 has a diameter of 8.5 in. The material is 65-45-12 Ductile Iron.
65-45-12 Ductile Iron is used to machine pistons, glands, caps, manifolds, rams, and valve bodies.
Ductile has higher machining speeds than steel and there is usually no need for deburring machined parts. The graphite flakes in the material act as a self-lubricant. Ductile can be flame or induction hardened as well as deep hardened.
Ductile bars are produced with sufficient stock on the outside diameter to ensure clean-up at the nominal dimension.
Material longer than 48 inches may have additional freight charges.
