By Mike Osenga02 July 2018

Dura-Bar, Woodstock, Ill.  has announces the availability of a new ductile iron grade—Solution Strengthened Ductile Iron or SSDI. With improved strength and ductility, SSDI is being positioned by Dura-Bar as an alternative to 1045 steel used in a oil and gas and fluid power applications.

One of the key features of SSDI, Dura-Bar said, 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.

Solution Strengthened Ductile Iron is a metallurgical term that has been adopted by the producers of ductile iron. SSDI, from Dura-Bar, has a minimum tensile strength of 75,000 psi, a minimum yield strength of 55,000 psi and a minimum elongation of 15 percent. SSDI also boasts a tightened Brinell Hardness (BHN) for consistency throughout the material.

SSDI is seen as especially applicable for rotors used in air and natural gas compressors as well as hydraulic manifolds and cylinders used in fluid power applications. It can also be used in oil and gas applications such as plug valve inserts and crossheads. SSDI is initially available in 1 in. to 9 in. rounds, 3.25 in. and 3.75 in. squares as well as 6.25 in. by 7.25 in. rectangles.
