Detailed description:

Alloy tool steel: CrWMn
Standard: GB / T 1299-2000

Features and application:
Is applied more widely in cold-working die steel, known as "non-deformable steel", but more sensitive to the formation of network carbide. Is mainly used to request quenching distortion is very small, long and complex shape of the cutting tool (such as pulling a knife, long tap, long reamer, special cutters), and measuring tools (such as the die, block gauge, gauge-like columns, sample sets) as well as the cross-section is not the shape of the high-precision Die, etc. complex.
