Nickel based alloy for application to similar nickel based steels of Inc 625 or similar. This alloy is used in branches of the air and space as well as the chemical industry. The weld is distinguished by its long term corrosion resistance, stability against tension cracks and heat cracks. It has a high tensile strength and tenacity even at temperatures up to 1100°C and cold tenacity down to 196°C. Due to the alloy elements Mo and Nb in the NiCr matrix an unusually high fatigue resistance can be achieved.
