Product Description
Steel O1 Annealed is a high-carbon, oil-hardening tool steel known for its dimensional stability, excellent edge retention, and ease of machining in the annealed condition. Commonly used in tool and die applications, it offers a strong balance of hardness, toughness, and workability—especially for intricate CNC-machined tools.
The annealed version of O1 is softer and more machinable, making it suitable for precision shaping prior to hardening. Once heat-treated, it delivers outstanding wear resistance and maintains sharp edges, making it ideal for cutting tools, dies, and punches.
At TECHNO CNC, O1 is supplied with full traceability, custom cut sizes, and optional hardened or ground finishes for faster integration into manufacturing processes.
Additional Information
| USES | Short-run tooling for dies, cutting tools operating at ambient temperature. |
