Cold work tool steel used for manufacturing cutting, bending, pressing, and embossing tools, as well as stamps, bending rails, and knives.
Due to its high carbon content, 1.2436 is particularly suitable for wear-resistant applications.
1.2436 is a ledeburitic 12% chromium steel that can be hardened with relatively simple methods.
It generally offers good machinability, but for improved machinability in the hardened state, consider using 1.2379, TENASTEEL, or Daido DCMX.
You can obtain this material from us as precision flat steel (standard and custom dimensions) and as raw material cut-to-size.
We also offer 1.2436 customized according to your specifications as a finished machined drawing part.
