Based in the industrious heart of Hamilton, New Zealand, Neesham Flanges has built a reputation for precision and reliability in the supply of high-performance components. Our focus on Hastelloy Plate Flanges reflects a commitment to serving demanding industries with solutions that can withstand the most challenging environments. We understand that in sectors like chemical processing and offshore engineering, failure is not an option, which is why we ensure every flange we manufacture and supply meets the highest standards of quality and material integrity, right here from our New Zealand base.
The exceptional qualities of Hastelloy stem from its sophisticated nickel-chromium-molybdenum composition, often enhanced with elements like tungsten. This alloy family is specifically engineered to retain its strength and resist an extraordinary range of threats, including pitting, corrosion from chlorides, and oxidation at high temperatures. These plate flanges are crafted to maintain their structural integrity and mechanical properties, offering superior performance where ordinary stainless steels would quickly succumb, ensuring a long service life even under the most severe thermal and chemical stress.
