These washers are mainly made from nickel, molybdenum, and chromium, with some tungsten, iron, and cobalt thrown in. This unique blend gives them remarkable resistance to both reducing and oxidizing agents, as well as protection against localized corrosion such as pitting and crevice attack. On the mechanical side, they boast high tensile and yield strength, toughness, and resistance to stress corrosion cracking, making them reliable in tough industrial settings where temperatures and pressures can vary widely.
Hastelloy Washers find their place in various industries that deal with extreme chemical and thermal conditions. In chemical processing plants, you’ll see them in reactors, heat exchangers, and piping systems that handle aggressive media. Petrochemical facilities use them in pumps, valves, and scrubbers that come into contact with corrosive fluids. In marine applications, they’re essential for shipbuilding, offshore structures, and seawater equipment. Power generation industries rely on them for turbines, flue gas scrubbers, and boilers. Their unbeatable combination of strength, durability, and exceptional corrosion resistance makes Hastelloy Washers a must-have for critical engineering and industrial applications.
