Bohler CN 19/9 M-IG description: GMAW wire of type G 20 10 3 / (308Mo). This wire is designed for dissimilar joints and weld cladding. BOHLER CN 19/9 M-IG offers a lower chromium and ferrite content than a 309L 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 -60°C to +300°C.
