Rebuilding die casting moulds

TIG rod for welding Cr/Mo and Cr/Mo/V steel with 5% Cr.

The deposit has a high fatigue resistance, is resitant against thermal shocks and creep resistant.

Workingtemperatures up to 600 °C (1112 °F).

Specifications & Usage


Repairing die casting moulds and injection moulds.

Welding pipelines and boilers in the petrochemical industry (12CrMo 19 5 , wn°1.7362, 1.7363, ASTM A 335 gr P5).

Hardness: 32 HRC


Preheating depends on the type of base metal (as a guideline, use 300-350 °C (572-662 °F), for steel with 5% Cr).

Heattreatment after welding (steel with 5% Cr): 750 °C (1382 °F) - 1h + cooling in furnace.
