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 350C, and to oxidation up to 800C. It gives a stable arc and the slag is easy remove. Re-drying is 300°C-350°C min. 2 h
