Bohler-Uddeholm BÖHLER K294 MICROCLEAN AISI A11 Powder Metal Tool Steel
Categories:	Metal; Ferrous Metal; Tool Steel; Cold Work Steel
Material Notes:	Powder-metallurgical produced cold work tool steel with extremely high wear resistance, good toughness and high compressive strength. The powder metal technology enables a clean and fine powder. The result is a significant increase in toughness and a more uniform carbide distribution. Applications: Punches and dies for blanking, piercing, cold heading and cold extrusions. Cold forming rolls. Knives for slitting, pelletizing and woodworking. Screws, nozzles and barrel liners for plastics compounding and injection molding. Powder metal compaction tooling.
