DEF STAN 02-835 is a hot forged, stress relieved high strength cupronickel developed primarily for marine and offshore applications. The alloy contains around 14.5% nickel, 4.5% manganese and smaller additions of aluminium and iron to increase the overall material strength and corrosion resistance. Specified as an MoD (Navy) grade, it combines the inherent corrosion resistance and antibiofouling benefits of traditional cupronickels whilst offering higher strength and toughness levels than the aluminium bronzes.
In addition to its high mechanical strength and general corrosion resistance, DEF STAN 02-835 also offers a good resistance to impingement, very good antigalling properties, a freedom from hydrogen embrittlement and a high impact strength. These attributes have enabled this material to be utilised not only in marine and offshore environments but also for high strength critical components in the chemical processing, general engineering and automotive industries.
