ES 308-17 Mo A5.4: E308 Mo - 17 / EN 1600: E 20 10 3 R 3 2
Description
ES 308 Mo - 17 is an Rutile electrode of type E 20 10 3 / 308Mo. This electrode is designed for dissimilar joints and weld cladding. E S 308 Mo offers a lower chromium and ferrite content than a 309MoL weld deposit with the result that carbon diffusion and Cr-carbide formation is reduced after post weld heat treatment and lower ferrite contents can be achieved in the second layer of 316L surfacing. Suitable for service temperatures from -80°C to +300°C. Safety against formation of porosity due to the moisture resistant coating. is an extra low carbon rutile coated electrode. It gives a filler metal of the Cr – Ni type. Excellent quality smooth weld beads are highly resistant to acids, inter granular corrosion at operating temperatures up to 350°C, and to oxidation up to 800°C. It gives a stable arc and the slag is easy remove. Re-drying is 300°C-350°C min. 2 h
