Alloy 601H is a nickel-chromium-iron alloy with additions of aluminium and titanium. It is characterized by:
- outstanding resistance to oxidation at high temperatures
- good resistance to carburizing conditions
- good resistance to stress-corrosion cracking
- good resistance at oxidating, sulfur-containing atmospheres good mechanical properties at both room and elevated temperatures due to solid solution hardening
