Dexter Foundry Introduces DuraDex Iron™

DuraDex Iron™ offers as-cast value compared to heat treated materials such as Quench & Tempered and Austempered Ductile Irons.

Fairfield, IA -- Dexter Foundry is proud to introduce DuraDex Iron™, a patent pending material for applications requiring abrasion resistance. DuraDex Iron™ offers as-cast value compared to heat treated materials such as Quench & Tempered and Austempered Ductile Irons.

Results from Dry Sand/Rubber Wheel; ASTM G65-04 show DuraDex Iron™ as-cast Abrasion Resistance Factor (ARF) exceeds Austempered Ductile Iron. In section sizes from ½ inch to 3 ¼ inch DuraDex Iron™ abrasion resistance ranges from 5.0 to 6.2 (ARF) compared to ADI wear resistance range of 4.3 to 5.6 (ARF). DuraDex Iron™ provides better abrasion resistance at lower bulk hardness and up to 30% less cost than Austempered Ductile Iron.

The DuraDex Iron™ process offers Dexter Foundry customers the opportunity to have their products as cast, with no heat treatment,” said Tom Jones, Vice President and General Manager for Dexter Foundry, Inc. “This enables us to offer a lower transportation cost, lower overall cost and shorter lead time for our clients. Dexter Foundry can work with your engineers to tailor Duradex Iron’s™ microstructure to your custom application."
