Material Notes:

AQUAMET 18 is an austenitic stainless steel with corrosion resistance comparable to that of Type 304. Its good strength and toughness make it an ideal shafting material for workboats. It provides a stainless alternative to ABS Grade 2 carbon steel shafting, but requires no sleeves nor fiberglass. In certain large diameters, it does offer a strength advantage over AQUAMET 19. (See properties below.) It is frequently used on pusher tugs, tow boats, supply boats and fishing trawlers. NOTE: AQUAMET 18 is currently available by special order on a heat lot basis only.Information provided by Crucible Specialty Metals.
