4mm & 5mm Incoloy Alloy 800/800H Nickel-Chromium Bars with 30-35% Nickel Content for High-Temperature Applications
Incoloy 800HT demonstrates exceptional resistance to sulfuric acid environments and maintains excellent performance in chloride, phosphoric acid, and nitric acid applications. The alloy contains niobium for stabilization against sensitization and intergranular corrosion.
Incoloy 800H is an austenitic heat-resistant alloy engineered for high-pressure structures operating at elevated temperatures. The enhanced strength is achieved through carbon, aluminum, and titanium additions, with annealing at minimum 1149°C to achieve ASTM5 or coarser grain size.
