Boron Nitride Ceramic Washers and Seals Prevent Galling in High Temperature Bolted Assemblies

Boron nitride ceramic washers and seals are now helping engineers solve a long-standing problem in high-temperature bolted assemblies: galling. Galling happens when metal parts stick together under heat and pressure, making disassembly difficult or even impossible. This issue is common in industries like aerospace, energy, and manufacturing where equipment runs at extreme temperatures.

Traditional metal washers often fail in these conditions. They can weld themselves to bolts or flanges during operation. Boron nitride ceramics offer a better solution. They stay stable at temperatures above 1,000°C and do not react with most metals. Their low friction surface keeps parts from seizing, even after repeated thermal cycles.

These ceramic components also resist corrosion and electrical conduction, adding extra protection in harsh environments. Engineers can install them just like standard washers or seals, with no need for major design changes. That makes adoption easy and cost-effective.

Recent field tests show bolted joints using boron nitride washers stayed free of galling after months of service in high-heat settings. Maintenance crews reported faster, safer disassembly with no damage to surrounding parts. The parts held up well under vibration, thermal shock, and chemical exposure.

Manufacturers are now offering these washers and seals in a range of sizes and shapes to fit common industrial applications. They work with stainless steel, Inconel, titanium, and other high-performance alloys. As demand grows for reliable high-temperature solutions, boron nitride ceramics are becoming a go-to choice for critical fastening systems.
