Metrode Met-Hard-750TS description: This electrode gives a Mo alloyed high speed tool steel deposit with hot hardness (up to 600°C), good toughness and crack resistance (similar to AISI M1). Used for the reclamation, repair and modification of high speed cutting and machining tools in either the as-welded, tempered or rehardened condition. New tools can be manufactured by overlaying mild or alloyed steel blanks, annealing to facilitate machining, quenching and tempering to required hardness. Applications include cutting and piercing tools, dies and drills, punches and knives, ingot tongs etc.
