Special notes |
Claddings and buffer layers are already corrosion-resistant in the first layer. Even with higher dilution rates, there is no risk of martensite formation (root welding). Operating temperatures for black-white connections max. +300°C. For prolonged annealing treatment above +300°C, nickel-based welding consumables must be used. |
