Dura-Bar ductile iron is a cost-saving alternative to low-medium carbon steels and has similar strengths with excellent free machining properties.
Dura-Bar gray irons provide a wide range of improvements through machinability, strength, hardness and wear capabilities.
Dura-Bar brings many advantages over steel, and several were realized by the manufacturer of hydraulic cylinder pistons. Machinability, wear resistance and part life were all issues that needed solutions fast. Dura-Bar provided those solutions which resulted in a total part cost reduction.
With improved strength and ductility properties, SSDI is an excellent alternative to 1045 steel used in a wide variety of oil and gas and fluid power applications. One of the key features of SSDI is the enhanced machinability due to the addition of silicon. Machining trials have yielded minimum productivity increases of approximately 30 percent with no negative impact in tool wear.
