Good ductility, toughness, excellent resistance to cavitation and to stress corrosion cracking. Low amount of diffusible hydrogen guaranteed (<4 ml/100 g). A post-weld heat treatment at 580 °C to 620 °C is recommended to obtain a soft martensite structure. Joining and rebuilding of stainless martensitic and martensitic-ferritic steel base metals. *Classified EC410: Out of AWS standard regarding Mn > 0.6 and Si > 0.5. Mo: 0.5 690 830 18 -20 °C: 110 Mo: 0.5 670 830 19 -20 °C: 42 Mo: 0.9 670 860 17 -20 °C: 60 Soft martensitic deposit CrNiMo, type 16 5 1 / 17 6. Good ductility, toughness, excellent resistance to cavitation and to stress corrosion cracking. Low amount of diffusible hydrogen guaranteed (<4 ml/100 g). Better pitting corrosion resistance compared to 410NiMo. A post-weld heat treatment at 580 °C to 620 °C is recommended to obtain a soft martensite structure. Joining and rebuilding of stainless martensitic and martensitic-ferritic steel base metals. Classified Z: 16 5 1 / 17 6 are not referenced in ISO standard. *Not referenced in AWS standard. Mo: 0.9 650 850 15 +20 °C: 30 - 460 580 35 -60 °C: 40 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 base metal compositions. To be used as a buffer layer if cladding with 308L. We also offer 309LNb, which can be used as a buffer layer when cladding 347, and 309LMo for cladding 316L. Co: 10.5 Mo: 0.25 N: 0.3 As welded: 240 HB Work hardened: 50 HRC Austenitic deposit of highly alloyed CrCoMn steel strengthened with nitrogen. Superior cavitation resistance, comparable to Co-base alloys. Exposed to cavitation, a phase transformation occurs and the deposit hardens. The microstructure becomes martensite and forms a hard surface layer. Demonstrates high resistance to cavitation, corrosion and erosion. Mo: 5.5 Fe: 3.0 Co: Bal. As welded: 33 HRC Work hardened: 47 HRC Low carbon cobalt base. Low cracking tendency. Ideal choice for resistance to multiple combinations of stress, such as corrosion and cavitation. Maintains a good level of hardness at high temperatures. Can be work hardened and polished. Low coefficient of friction. A special version is also available for GTAW, plasma and laser processes.
