GRIDUR TLK

IDENTIFICATION : GRIDUR TLK
CLASSIFICATION : AWS/SFA 5.13 : EFe5 -B DIN 8555 : E4 – UM - 60-ST

DESCRIPTIONS :

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.

TYPICAL APPLICATIONS :

  • Cutting and pearcing tools
  • Dies and drills
  • Ingot tongs
  • Blanking dies, shear blades, milling tools rolling mill guides etc.
