Description
Basic coated electrode
The weld deposit is high carbon 35Cr-45Ni-1Nb to match heat-resisting castings with great oxidation and carburization resistance for applications up to 1150°C. In the as-welded condition the multi-pass weld metal microstructure consists of austenite with primary eutectic and secondary precipitated carbides. For the thicker section materials a preheat may prove beneficial owing to the low ductility of the material. Typical applications include tubes for steam cracking pyrolysis transfer lines, pyrolysis furnace outlet lines and steam reformer headers in the petrochemical industry.
