Qu4842 is suitable for similar, heat-resistant rolled, forged and cast steels. Full austenitic
deposite metal. Preferred material against attacks of oxidated, azotic as well as gases
with a low oxygen content. Joint welding on heat-resistant Cr-Si-Al-steels which are
subject to sulphurous gases. Resistant to scaling up to 1.200°C. Tough at sub-zero
temperature up to -196°C. The temperature range between 605°C and 900°C should be
avoided becauce of the danger of brittleness.
