Rod electrodes coated with rutile for welding different types of steel and for build-up welding. Weld metal made of ferritic-austenitic chromium-nickel steel: scale resistant up to +1000°C.

DIN 8556: E 29 9 R 23, material no.: corresponds to 1.4337, AWS/ASME SFA-5.4: similar to ER 312 - 16, NF A 81 - 343: EZ 29.9 R 23, EN 1600: E 29 9 R 12.

Most important areas of application
Corrosion-resistant steels and cast steels, e.g. 1.4762 (X 10 CrAl 24)- 1.4085 (G-X 70 Cr 29): difficult-to-weld steels, e.g. construction steels of higher strength, manganese hard steels and pre-bonds with high-alloy steels; repairs and wear-resistant coatings.

Microstructure
ferristic austenitic

Special notes
The favourable coefficient of thermal expansion due to the high content of delta ferrite in the weld metal reduces the residual stresses in black/white joints and increases the safety against hot cracks.

Re-drying
Generally not necessary. However, the cladding tolerates re-drying up to +350°C.
