The addition of niobium results in a preferential reaction with carbon, which prevent the chromium from forming carbides. This improves corrosion resistance, increases strength at elevated temperatures and promotes a ferritic microstructure. It is used primarily in the automotive industry for welding catalytic converters and other parts of the exhaust system. For best results, welding must be done in a low heat input procedure and is not recommended for multi-pass applications.<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<p>&nbsp;<\/p>\n<h5>\u25b6\ufe0e <strong>Notes on Usage<\/strong>:<\/h5>\n<p>1.
