Description
Rubtilum coated Rod electrodes for welding stainless claddings and various types of steel. Weld metal made of austenitic chromium-nickel steel with particularly low carbon content for operating temperatures up to +350°C; heat resistant up to +1200°C.
DIN 8556: E2512LR23, material no.: corresponds to 1.4332, AWS/ASME SFA-5.4: similar to E 309 L-16, B.S.2926: 23.12 LR, NF A81-343: EZ 23.12 LR 26, EN 1600: E2312LR32.

Special notes
Claddings and buffer layers are already corrosion-resistant in the first layer. No risk of martensite formation (root welding) even at higher degrees of fusion. Maximum operating temperatures for black/white joints +300°C. Nickel-based filler metals must be used for prolonged annealing or operating temperatures above +300°C.
Re-drying
Generally not required. However, the coating can withstand re-drying up to +350°C.
