Hardened Easy-to-Machine P20 Tool Steel
- Yield Strength: 101,000 psi
- Hardness: Rockwell C25 (Hard)
- Fabrication: See table
Hardened to resist impact and abrasion, P20 tool steel is also strong and easy to machine because of its low carbon content. It has the wear resistance and highly polishable surface needed to fabricate long-lasting molds and dies.
