Nestled in the heart of Naypyidaw, Wai Nickel Alloys stands as a dedicated manufacturer and supplier, committed to providing exceptional materials for demanding industrial applications. We take pride in our specialized production of Incoloy 800, 800H, and 800HT nuts, components engineered to deliver unwavering reliability. Our focus is on precision manufacturing and stringent quality control, ensuring that every nut we supply meets the rigorous standards required for high-temperature and corrosive environments, supporting the robust infrastructure and industrial growth of Myanmar and beyond.
The strength of these alloys lies in their carefully balanced composition, primarily nickel, iron, and chromium, with the addition of titanium and aluminum for stability. This formulation grants the 800 series nuts outstanding mechanical properties, including high tensile strength and remarkable creep resistance, especially in the 800H and 800HT grades which are optimized for sustained performance under extreme heat. This combination allows them to maintain their integrity and resist deformation under heavy loads and prolonged exposure to elevated temperatures.

You’ll typically find Incoloy 800, 800H, and 800HT nuts hard at work in some of the most challenging settings imaginable. They are essential components in petrochemical processing plants, within the heat exchangers and furnace systems of power generation facilities, and in the demanding environments of thermal processing and nuclear engineering. Their exceptional resistance to oxidation and carburization makes them the go-to choice for fastening critical components that must endure intense heat and aggressive chemical atmospheres without failing.
