Dura-Bar is stocked in several grades of ductile and gray iron, as well as additional non-stock grades which can be ordered in volume quantities from our distributors. The type and distribution of graphite influences most of the properties and results in the free machining characteristics, excellent noise and vibration damping, thermal conductivity and wear resistance.
|Iron||Stock Grades||Non-Stock Grades|
|Gray||G2, G2X, G2S, G2P||G1A, G2A|
|Ni-Resist||201 Type 1||n/a|
Dura-Bar 65-45-12 and 80-55-06 ductile irons conform to ASTM A536, and are often used as an alternative to plain carbon steel, having similar strengths with excellent free machining properties.
Dura-Bar gray irons have flake configurations corresponding to ASTM Type VII, D or A, fitting a variety of applications requiring strength, vibration damping, heat treat response, wear resistance and machining finish.
Dura-Bar Ni-Resist 201 Type 1 conforms to ASTM A436, Type 1. It contains flake graphite in an austenitic matrix with 10% carbides, and is often used in corrosive environments.
Dura-Bar XL permanent mold ingots expand the Dura-Bar size range to 26" diameter in grades 65-45-12 ductile and G2 gray. Ingots are proof turned to provide an excellent machining surface and there is no sand involved in the process.
Centerless turning, grinding, trepanning and milling are among the finishing options available for demanding-tolerance applications. Benefits include eliminating rough milling operations and removing the as-cast surface to increase insert life.
Dura-Bar offers over 1,000 individual sizes, providing you near-net shapes and saving valuable machine time. Filter by shape, grade and surface to find the closest size for your application.
