Detailed description:

Alloy tool steel: 6W6Mo5Cr4V
Standard: GB / T 1299-2000

Features and application:
Is a low-carbon high speed steel type of cold-working die steel, toughness better than the high-speed steel. As a cold extrusion of steel, have a higher life. This steel easy to decarburization. Is mainly used for cold extrusion die, the upper and lower red top mold.
