Features
Properties and Applications
Suitable for welding fabrication of dynamically loaded steel contructions, bridge, shipbuilding, pipe-line, pressure vessels, tanks, boiler and machines where high tougness is required. Weld metal recovery is appx. 115 %. Smooth and clean welds merging into base metal without undercuts. Good gap bridging properties. Welds are of X-ray quality. It is suited for depositing buffer layers on higher carbon steels.
