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.
