These stud bolts are mainly made from nickel, molybdenum, and chromium, with some tungsten, iron, and cobalt added in. This sophisticated blend gives them remarkable resistance to both oxidizing and reducing agents, as well as protection against localized corrosion like pitting and crevice attack. On the mechanical side, they boast excellent tensile and yield strength, toughness, and resistance to stress corrosion cracking, all while maintaining stability in fluctuating temperatures and high pressures. Their unique combination of chemical and mechanical properties makes them ideal for critical industrial applications.
Hastelloy Stud Bolts find their place in industries that face highly corrosive and high-temperature conditions. In chemical processing, they are used in reactors, piping systems, and heat exchangers that handle aggressive fluids. Petrochemical plants rely on them for pumps, valves, and scrubbers that endure harsh chemical exposure. In marine applications, they are essential for shipbuilding, offshore platforms, and seawater handling equipment. Power generation facilities depend on them in turbines, boilers, and flue gas scrubbers. Their durability and ability to withstand severe operating conditions make Hastelloy Stud Bolts a must-have for critical engineering and industrial applications.
