DURWELD NiCoMo

• Electrode with an alloyed core and a special basic coating.
• Dedicated to the repair of dies and punches, especially those exposed to a huge impact.
• Recommended especially for H13 type martensitic steels and martensitic maraging steels.
• The deposit is very easily machined mechanically.
• Can be heat treated if higher hardness is required. A further increase in hardness can be obtained by the nitration process.
• The weld deposit significantly increases the hardness of the welded edge of cold cutting tools and blades.

Recommendations:

• In many cases, it can be used without the need to preheat the base material.
• When hardfacing high carbon steels, it is recommended to preheat and apply the buffer layer using the INOX R312 electrode.
• It is recommended to use small electrode diameters, which allows to limit the influence of heat on the base material in order to avoid loss of hardness of the overlay.
• Hardening of the deposit can be achieved by annealing for 4 hours at 480°C and subsequent slow cooling (50°C/1h).
