AQUAMET 22 is a high-alloy austenitic stainless steel that provides superior corrosion resistance along with excellent toughness and high strength. It has higher strength than AQUAMET 17 in diameters of ¾" through 1¼", and equivalent strength in diameters up to 2". Due to its high alloy content, AQUAMET 22 resists pitting and crevice corrosion and is ideal for pleasure boats which are operated infrequently, spending much of their time tied up at docks. (AQUAMET 22 H.S., a higher strength version, is available in 2½" to 6" diameters.)
