Dura-Bar will be showcasing its series ductile iron for manifold applications and its new Solution Strengthened Ductile Iron at this year’s Fluid Power Technology Conference at the Milwaukee School of Engineering. Visitors can see this and other Dura-Bar technologies at booth 203 at the FPTC May 15-16.
Better under pressure: Dura-Bar’s ductile iron for manifold applications
Pressure ratings for hydraulic manifolds made from ductile iron have historically been based on book values and conservative theoretical calculations, making design engineers reluctant to specify it in lieu of steel for applications involving more than 5,000 psi. Dura-Bar is now pressure rated to 6,500 psi and conforms to NFPA standard T2.6.1 R2-2000.
The trend in today’s mobile hydraulic systems is toward more complexity and higher working pressures. More pressure means more efficiency for the user of a hydraulic system, but more challenges for the system’s manufacturer who typically uses components like seals, valves, and manifolds. Dura-Bar’s superior machinability also comes into play by facilitating drilling, and with little or no deburring it can reduce the overall cost to produce a manifold.
A sneak peek at Dura-Bar SSDI
Dura-Bar continues to innovate within the industry and has developed a new grade of ductile iron, Dura-Bar SSDI (Solution Strengthened Ductile Iron). This new product combines the elevated mechanical strengths of a pearlitic ductile iron along with the machinability of a ferritic ductile iron. In combining the best of both worlds, Dura-Bar SSDI will fill a void in the marketplace that provides benefits for both the designing and manufacturing metal parts. Considerable cost savings can also be accounted for in the machining of Dura-Bar SSDI.
