Basic coated electrode depositing molybodenum alloyed high speed steel with hot hardness (upto 6000C) coupled with toughness and crack resistance. New tools can be manufactured by overlaying mild or alloyed steel blanks, annealing to facilitate machining, quenching and tempering to give required hardness.
