180 HV | NT® HA C-22: characterised by higher corrosion resistance in an oxidising atmosphere than NT® HA C-4, NT® HA C-276, and NT® IN 625; especially high resistance to pitting corrosion and stress-corrosion cracking | PTA PS HVOF |
| NT® HA C-276 | C Si Cr Fe Mo W V Co |
< 0,01 < 0,08 15 5,0 16,0 3,0 0,35 < 2,5 |
180 HV | Corrosion-resistant Ni-Cr-Mo alloy with added tungsten for a wide range of applications; very high resistance to corrosion in numerous aggressive media; especially resistant to pitting and crevice corrosion because of the high molybdenum content; decreased carbide precipitation during welding because of the low carbon content, and thus retention of the corrosion-resistant property after welding; application in environmental protection and chemical process technology, cellulose and paper manufacturing as well as waste-recycling plants | PTA PS HVOF |
