Our 1.2379 tool steel is a premium material widely recognized across industrial sectors for its exceptional wear resistance and inherent toughness. It serves as the direct European equivalent of the standard ASTM D2 grade, containing approximately twelve percent chromium to provide slight corrosion resistance. While their fundamental chemical compositions remain nearly identical, our European-grade material undergoes significantly stricter refining processes. This advanced production method results in a superior grain structure and highly consistent heat treatment performance compared to standard D2 cold work steel.

Our high-quality SKD11 steel provides outstanding durability for continuous production runs, ensuring reliable dimensional stability under severe industrial usage. The precise high carbon and chromium content grants excellent edge retention, allowing precision tools to maintain a sharp cutting edge over extended periods. This characteristic significantly minimizes tooling replacements and reduces overall maintenance downtime for demanding manufacturing facilities.
Through rigorous production routes including electric arc furnace, ladle furnace, vacuum degassing, and optional electro-slag remelting processes, we ensure a highly uniform internal microstructure. This strict control over the refining process allows our premium material to achieve a reliable hardness of up to 250HB when supplied in the annealed condition, effectively minimizing the risk of distortion during subsequent heat treatments.
We supply this premium industrial material in multiple customized surface conditions to accommodate diverse heavy machining requirements. Clients can conveniently select from black surface, turned, milled, peeled, grinded, or precision finish milled options. Offering these varied initial conditions significantly reduces the preliminary preparation time and machining costs for specialized industrial tooling projects across various sectors.
Our robust material remains the standard choice for manufacturing high-stress blanking dies, heavy-duty punching tools, and precision shear blades. Its reliable intrinsic toughness prevents catastrophic chipping or cracking during demanding metal fabrication tasks. Toolmakers consistently rely on this grade to produce components that can handle repetitive high-impact forces without compromising the final product quality.
Manufacturers extensively utilize our high-carbon tool steel in demanding forming operations. It performs exceptionally well in thread rolling dies, cold extrusion tools, and deep drawing dies where internal material integrity is absolutely paramount. The superior compressive strength ensures the tooling maintains exact dimensional tolerances even under extreme operational pressure.
This specialized grade is frequently selected as mould steel for processing abrasive polymers and complex plastics. It effectively resists the rapid abrasive wear that would quickly degrade softer metal grades, extending the operational lifespan of expensive injection moulds. This makes it an invaluable asset for plastic manufacturers handling tough composite materials.
The exceptional toughness makes our wear resistant tool steel highly suitable for manufacturing durable granulator blades and heavy-duty recycling knives. It effortlessly withstands repetitive aggressive impacts while processing tough industrial waste materials. This reliability ensures uninterrupted operation in recycling plants where equipment failure causes significant processing delays.
