Taseto RNY312 description: Since TASETO RNY312 contains a large amount of ferrite, its crack sensitivity is very low at the case of dissimilar welding. This electrode is used for welding stainless steel to carbon steel or to low alloy steel with high carbon content, also welding the first layer of overlay welding on carbon steel or to low alloy steel with high carbon content. RNY312 is a lime-titania type electrode suitable for positional welding.
