Austempered Ductile Iron (ADI) gear segments used in the mining industry.

gear-segmentsThese gear segments are used in rail tipping assemblies that empty entire rail cars of ore. The alloy use for the gears has a tensile strength of 150,000 PSI a yield strength of 100,000 PSI with 7% elongation. The gears are 100% X ray inspected.

ADI is chosen for this tough application due to the strength of the alloy and the surface hardening effect on the gears. The top .0015” of the gear tooth will harden to nearly 600BHN when subjected to impact.
