Maraging steels (derived from Martensitic and Aging) were first developed in the 1960s as high-strength constructional steels for the aviation and space technology. Key features are their comparatively high toughness levels at maximum tensile strength.

Advantages claimed for the new EutecTrode XHD 6860 and 6855XHD include smooth, regular weld surface requiring minimal machining, low temperature ageing treatment which eliminates quenching defects and distortion, retention of  aged hardness up to higher service temperatures, as well as good weldability without preheating for practical engineering applications.

Enrique Matey, business unit manager for welding consumables in the Castolin world, explains: “Originally intended for Die casting aluminum, but due to its spectacular new properties, 6860 XHD will be perfectly adapted to other industrial sectors like forging, hot stamping, cold and semi-hot cutting tools, plastic injection and many other applications we are still discovering daily with this new alloy recently released”.
