Due to their excellent corrosion resistance and mechanical properties, Hastelloy washers can be found throughout many industries. They are often used to create components on the processing side of chemical manufacturing (i.e. reactors, pumps, valves, and piping systems), which may experience exposure to strong acids, alkalis, and oxidizers. They are used frequently in marine and offshore applications and in desalination facilities, as well as in wastewater treatment processes because of how well they perform in the presence of saltwater and other corrosive environments. They are also very common in the pharmaceutical industry and the pulp and paper industry and utilitzed within the power generation industries. Because of their ability to withstand extreme temperatures and pressures, and provide reliable functioning through demanding service conditions, Hastelloy washers form an integral component of today’s highly demanding industrial applications where safety and product longevity are critical.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
