Material Notes:
Description: Micro-Melt® 9 tool steel is a high vanadium tool steel produced using the Carpenter Micro-Melt powder process. This grade possesses wear resistance superior to most other tool steels along with good strength and toughness characteristics. In addition, it provides higher toughness characteristics than Micro-Melt® 10 alloy with slightly lower wear resistance. Micro-Melt 9 tool steel changes size only slightly after hardening. An expansion of about 0.0005 inches/inch is typical.Applications: punches, dies for blanking, piercing dies, forming rolls and dies, cold heading, steel mill rolls, cold extrusion, slitter knives, shears, pelletizer blades, nozzles, woodworking tools, cold extrusion barrels, cold extrusion liners, plastic injection molds, compacting toolsInformation provided by Carpenter Technology Corporation.Micro-Melt® is a registered trademark of Carpenter Technology Corporation.
