Wear-Resistant High-Speed M4 Tool Steel Bars
- Yield Strength: 60,000 psi
- Hardness: Rockwell B95 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C65
These bars are also known as flat stock. Made from powdered metal, M4 tool steel has a consistent microstructure that gives it outstanding resistance to wear and abrasion. It is comparable to CPM Rex M4. Use it for punches, dies, and high-speed cutting tools. These bars are decarb-free for a uniform surface that will consistently accept heat treating.
