Nestled in the heart of Naypyidaw, Wai Nickel Alloys stands as a dedicated manufacturer and supplier of high-performance components, built on a foundation of precision and reliability. We specialize in crafting Incoloy 800, 800H, and 800HT bolts, providing our clients with critical fastening solutions that are engineered to excel under the most demanding thermal and corrosive conditions. Our commitment is to deliver not just a product, but a promise of enduring strength and stability for the most challenging industrial applications.
The exceptional performance of these bolts stems from their unique composition, a robust nickel-iron-chromium alloy enhanced with titanium and aluminum. This formulation grants them outstanding resistance to oxidation and carburization. Mechanically, they are defined by impressive tensile strength and remarkable creep-rupture properties, especially in the 800H and 800HT grades, which are thermally treated to maintain their integrity and resist deformation even when exposed to sustained high temperatures.
