D-Series High-Temperature Bolts for Liebherr PR736 Bulldozers, PR746 Bulldozers - Turbocharger Connecting Bolts, High-Heat Resistant and Oxidation-Resistant
The turbochargers of Liebherr PR736 and PR746 bulldozers work at extremely high temperatures. This D-series high-temperature bolt is specially designed for their connection. Made of nickel-based superalloy material, it can maintain stable mechanical properties in a high-temperature environment above 700℃, with excellent oxidation resistance, and is not easy to embrittle after long-term use. The thread precision of the bolt reaches 5g grade, which fits closely with the flange surface of the turbocharger to ensure sealing performance and prevent exhaust gas leakage. The surface is treated with high-temperature coating, which can effectively isolate heat transfer and reduce stress deformation of the bolt due to temperature changes. The bolt has passed strict high-temperature fatigue tests and can still maintain high strength under repeated cold and heat cycles. It is a key connecting part for the safe operation of the turbocharger, suitable for high-intensity operations of high-power bulldozers.
