Description

2.4819 (NiMo16Cr15W) is a wrought nickel-chromium-molybdenum-tungsten alloy which displays remarkable corrosion resistance in a very wide range of processing environments. It offers excellent resistance to stress corrosion cracking and oxidising atmospheres up to 1040°C, whilst the high molybdenum content gives the alloy its excellent resistance to pitting and crevice corrosion. The low carbon content prevents the formation of grain boundary precipitates during welding. It shows the following features and properties:


  • Excellent resistance to pitting and corrosion
  • High mechanical properties
  • Excellent resistance to oxidising atmospheres up to 1040°C
  • Very high resistance to many aggressive chemicals
  • Related Standards
