Solution Strengthened Ductile Iron now available from Dura-Bar 

Published by
Oilfield Technology,

Dura-Bar announces the availability of a new ductile iron grade – Solution Strengthened Ductile Iron or SSDI.

With improved strength and ductility, SSDI is an 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% 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 and is gaining increased interest from numerous customers for a variety of applications. 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%. SSDI also boasts a tightened Brinell Hardness (BHN) for consistency throughout the material compared to other similar ductile iron alloys.

SSDI is an ideal choice 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.
