DEF STAN 02-833 / NES833

DEF STAN 02-833 (NES833) is a nickel aluminium bronze similar to CA104. The main difference being that DEF STAN 02-833 has been manufactured in accordance with the MoD’s Navy requirements. To improve the corrosion resistance of the material the standard states the nickel content must always exceed the iron content. Impact values are also taken on all sizes above 15mm diameter and the material is ultrasonically tested.
