These screws are primarily made from nickel, molybdenum, and chromium, with some additions of tungsten, iron, and cobalt. This unique blend offers remarkable resistance to both oxidizing and reducing agents, along with excellent protection against localized corrosion like pitting and crevice attack. On the mechanical side, they boast high tensile and yield strength, durability, and resistance to stress corrosion cracking, all while maintaining their shape and toughness even in extreme temperatures and pressures.
Hastelloy Screws are a go-to choice across industries that operate under tough conditions. In chemical processing plants, you’ll find them in reactors, heat exchangers, and piping systems that come into contact with corrosive fluids. Petrochemical facilities depend on them for pumps, valves, and scrubbers that handle aggressive chemicals. In marine settings, they’re essential for shipbuilding, offshore platforms, and seawater equipment where corrosion resistance is crucial. Power generation facilities utilize them in turbines, boilers, and flue gas scrubbers. Their ability to consistently perform under extreme conditions makes Hastelloy Screws vital for critical engineering and industrial applications.
