Welding of titanium or niobium stabilised stainless steel base metals with similar compositions, type 321 and 347 or 304L. When cladding, use 309LNb for the buffer layer. Suited to applications in the food, pharmaceutical, nuclear and fabrication industries. Mo: 2.9 500 700 35 +20 °C: 55 Austenitic deposit of CrNi steel with addition of Mo, type 316L. Molybdenum improves intergranular corrosion resistance in humid conditions. Service temperatures range from -196 °C to +400 °C. Welding of stainless steel base metals with similar compositions or stabilised with titanium and niobium. When cladding, use 309LMo for the buffer layer. Ideal for applications in the food, chemical, oil and gas, nuclear and fabrication industries. Mo: 0.4 670 800 22 +20 °C: 35 Austenitic-ferritic deposit of CrNi steel with a high percentage of Cr, type 312. Chromium ensures a high ferrite ratio for exceptional resistance to cracking. Good wear and friction resistance. Welding of dissimilar joints, high carbon equivalent or unknown steel base metals. Suited to maintenance applications, gear teeth, tool steels. - 490 670 40 +20 °C: 80 Work hardening austenitic deposit of CrNi steel with addition of Mn, modified type 307. Service temperatures range from -120 °C to +400 °C. Joining of 14% Mn austenitic steel base metal and dissimilar joints for high temperatures. Repair jobs where high strength and toughness combined with work hardening are required. Suitable for rail applications and the defence industry. TRI V 19 9 6-O is the equivalent wire that can be used for out of position welding. *Classified E307: Out of AWS standard regarding Mo < 0.5 and Mn > 4.75 to prevent from hot cracking. - 560 680 35 +20 °C: 45 Austenitic deposit of highly alloyed CrNi steel, type 309L. Service temperatures range from -60 °C to +400 °C. Joining of steels with similar and dissimilar composition base metals. To be used as a buffer layer when cladding with 308L.
