Dura-Bar XL

Dura-Bar XL is produced using the permanent mold casting method and expands the Dura-Bar size range. Dura-Bar XL is turned to 21, 23, 24, 25 and 26 inch diameters (guaranteed to finish 1/4" under turned dimension). The molds are considered "permanent" because they can be used multiple times before being replaced, lowering the cost of the product over methods that require a mold expense for each pour.

Dura-Bar XL is produced using the same quality molten iron as continuous cast Dura-Bar and is proof-turned for an excellent machining surface. The permanent mold casting method makes use of reusable metal molds in place of sand-based molds, which eliminates contamination and product defect problems common to sand castings and traditional foundries.

Dura-Bar XL is produced in three grades: 65-45-12 (Ductile Iron)80-55-06 (Ductile Iron) and G2 (Gray Iron).

Family Grade Description
Ductile Iron 65-45-12

Ferritic Ductile Iron (ASTM A536) viewhide

This is the most machinable grade of Dura-Bar. The ferritic structure provides for excellent machinability with good surface finishes. It has optimal impact strengths and fatigue properties.

80-55-06

Partially Pearlitic Ductile Iron (ASTM A536) viewhide

The pearlite in this grade makes it more wear resistant and stronger than a mostly ferritic grade. Machinability, response to heat treat and surface finishes are good.

Gray Iron G2

Highly Pearlitic Gray Iron (Conforms to ASTM A48, Class 40) viewhide

This is the most common gray iron. It is well suited for applications requiring high resistance to wear and responds well to heat treatment.
