 Description and Applications
 Basic coated electrode is developed for welding of pressure vessel steels
 and creep resisting steels. It gives molybdenum alloyed weld metal which
 operating temperatures up to 530C. Preheating is not required but
 interpass temperature up to 250C.
 Weld metal has very low hydrogen content and easy to handle in all
 positions except vertical down.
