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. It is frequently used on pusher tugs, tow boats, supply boats and fishing trawlers. Information provided by Crucible Specialty Metals. |
