Perfect for applications in the Thermal Processing industry

RA333® can be used in a variety of applications, here are just a few examples:

  • Tube supports in refineries and coal fired boilers
  • Heat treating muffles, retorts, fan shafts and fixtures
  • Carbon fibre production muffles
  • Sulphuric acid plant stack dampers
  • Molten glass spinnerets
  • Flare tips
  • RA333 weld filler for repair welding of cast heat resistant alloys
  • Tire drop chutes for cement kilns

About RA333®

Due to the alloy’s high chromium, high nickel content and additional alloying elements, RA333® is highly resistant to carburisation, thermal shock and metal dusting.

The ultra-tough alloy holds its strength over a long period of time up to a staggering 1204°C. Moreover, RA333® is resistant to chloride ion and polythionic acid stress corrosion cracking.

RA333®  is an alloy of choice when traditional alloys such as RA330®, Alloy 600 and Alloy 601 are not suitable.
