XW-10 Material Detailed Information
XW-10 is a high-carbon, high-chromium cold work tool steel, developed for applications requiring high wear resistance, good toughness, and excellent hardness. It is commonly compared to D2 (AISI) and 1.2379 (DIN) but features improved toughness and machinability.
This steel is designed for blanking, stamping, forming, and shearing applications where long tool life and resistance to abrasive wear are critical.
Key Features
Superior Wear Resistance
- High chromium and vanadium content create a high-hardness matrix that resists wear.
- Suitable for blanking, stamping, and forming tools that undergo heavy use.
High Hardness & Edge Retention
- After heat treatment, XW-10 reaches 58-62 HRC, providing long tool life and cutting performance.
Good Machinability Compared to D2
- Improved microstructure refinement offers better machinability than traditional D2 steels.
High Compressive Strength
- Withstands high-pressure loads without deformation, making it ideal for punches and dies.
Moderate Corrosion Resistance
- Chromium content provides some corrosion resistance, but it is not a stainless steel.
- Suitable for dry working environments or lightly lubricated conditions.
