Rubtil coated Rod electrodes for welding of stainless claddings and various steels. 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.

Most important base materials
Heat and scale resistant ferritic and ferritic-austenitic steels

Microstructure
Austenite with increased content of delta ferrite

Special notes
Claddings and buffer layers are already corrosion resistant in the first layer. No danger of martensite formation even at higher degrees of melting. Operating temperatures for black/white joints maximum +300°C. For longer annealing or operating temperatures above +300°C, nickel-based filler metals must be used.

Re-drying
Generally not necessary. However, the sheath can withstand re-drying up to +350°C.
