Known commercially as AISI O1, our 1.2510 tool steel is a premium oil-hardening cold work steel. It contains specific additions of manganese, chromium, and tungsten to enhance its overall toughness. This oil-hardening cold work tool steel provides superior dimensional stability during heat treatment processes. Users often prefer this grade over high-chromium alternatives when working on intricate tool designs. It achieves high surface hardness while maintaining excellent edge-holding capabilities.

Our 1.2510 tool steel delivers exceptional machinability in the annealed condition to streamline your production. The enriched chemical composition ensures an optimal balance between wear resistance and operational reliability. This material resists cracking and deformation even during complex fabrication processes. Compared to grades like 1.2379, our O1 cold work steel offers better toughness for intricate and demanding configurations. It operates effectively without excessive downtime during prolonged heavy usage.
Maintaining precise shapes is critical for industrial tooling and precision instruments. Our material guarantees excellent dimensional stability throughout the entire heat treatment cycle. It is carefully engineered to minimize distortion when undergoing standard oil quenching. This stability makes it an ideal choice for manufacturing gauges, master tools, and complex guide rails. We supply it with varied surface conditions like machined or peeled to meet exact project tolerances.
This material is widely utilized within the global tool and die industry. It serves as the primary material for blanking dies, shear blades, and heavy-duty punching tools. The high surface hardness ensures consistent performance when cutting materials up to six millimeters thick. Toolmakers rely on our material to prevent edge wear during repetitive industrial shearing processes. It consistently outperforms lower-alloy alternatives in demanding manufacturing environments.
Precision forming tools require a strong foundation to endure high mechanical stress without failing. It is exceptionally well-suited for producing thread rolling dies, cold taps, broaches, and reamers. In the plastics industry, it functions perfectly for master cavity sinking hobs and mould steel inserts. We also operate a dedicated facility to process custom mould plates from this material according to specific client drawings.
