Service temperatures range from -196 °C to +400 °C. Welding of stainless steel base metals with similar compositions, type 301, 302, 303, 304L. When cladding, use 309L for the buffer layer. For use in the food, pharmaceutical, nuclear and fabrication industries. 430 600 35 +20 °C: 80 Austenitic deposit of CrNi steel stabilised with Nb, type 347. Nb improves intergranular corrosion resistance and mechanical properties at high temperatures. Service temperatures range from -196 °C to +400 °C. Welding of titanium or niobium stabilised stainless steel base metals with similar compositions, type 321, 347 or 304L. When cladding, use 309LNb for the buffer layer. Suited for applications in the food, pharmaceutical, nuclear and fabrication industries. 450 610 35 -100 °C: 50 Austenitic deposit of CrNi steel with addition of Mo, type 316L. Mo 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. For applications in the food, chemical, oil and gas, nuclear and fabrication industries. 410 640 35 -196 °C: 45 Fully austenitic deposit of CrNi steel with addition of Mo and Cu, type 385. Alloys improve corrosion resistance in concentrated acids and also yield strength. Service temperatures range from -110 °C to +400 °C. Welding of copper-free and overmatching leaner alloy stainless steels, such as 317L. Ideal for applications in phosphoric, sulphuric and acetic acid plants, salt and seawater environments. Classified Z: Out of ISO standard regarding no N addition. 630 800 28 -50 °C: 55 Austenitic-ferritic deposit of CrNi steel with addition of Mo, type 2209. Mo improves intergranular corrosion resistance in humid conditions. Outstanding corrosion resistance: PREN = Cr + 3.3 Mo + 16 N ≥ 35 and Critical Pitting Temperature = 25 °C. Welding of duplex stainless steel base metals and dissimilar joints. For applications in forging and/or casting parts, chemical, oil and gas plants. 630 800 23 -20 °C: 50 Austenitic-ferritic deposit of CrNi steel with addition of Cu and Mo, type 2553. Mo and Cu improve corrosion resistance in sulphuric acid environments. Outstanding corrosion resistance: PREN = Cr + 3.3 Mo + 16 N ≥ 40 and Critical Pitting Temperature = 40 °C. Welding of super duplex stainless steel base metals and dissimilar joints. For applications in forging and/or casting parts, chemical, oil and gas plants. Back to contents page
