State of the Art review of Seawater Corrosion Resistance and Antifouling of Copper Nickel (cupronickel) alloys covering 90-10 and 70-30 alloys. This paper examines surface films, localised corrosion, sand erosion, galvanic issues, sulfides and ferrous sulfate treatments as well as biofouling, boat hulls and offshore sheathing.
Copper-Nickel Alloys for Seawater Corrosion Resistance and Mar 26, 2000 · Both alloys contain small but important additions of iron and manganese which have been chosen to provide the best combination of resistance to flowing seawater and overall corrosion resistance. The 30% nickel alloy is stronger and can withstand higher seawater velocities but, for most applications, the 90-10 alloy provides good service at a
HASTELLOY G-35 alloyA nickel alloy with exceptional resistance to wet process phosphoric acid HASTELLOY® G-35® alloy (UNS N06035) was designed to resist wet process phosphoric acid (P 2 O 5), which is used in the production of fertilizers. Tests in real-world solutions indi-cate that G-35 alloy is far superior to other metallic materials in this acid.

Nr. 1.4438 An Austenitic Stainless Steel with High Levels of Chromium, Nickel and Molybdenum for Enhanced Corrosion Resistance When Compared with 304/304L and 316/316L Alloy 317L 08/2018 SandmeyerSteelAlloy selection for service in caustic soda70-30 C71500 31 - - - Bal 0.8 B171 B466 a - UNS numbers beginning with an N indicate a nickel alloy, but the definition of a nickel alloy is different than that used by ASTM. b - in ASTM specifications, most nickel alloys fall into the B specifications. However, due to a redefinition of a nickel alloy, a few alloys
