FCS K100 Tool Steel
FCS supplies its own-brand material; the following description refers to BÖHLER K100 solely as a technical comparison reference, not as the product being offered.K100 is a 12% cold work die steel from ledeburitic produced by BÖHLER (Austria). It is characterized by a high-carbon and high-chromium structure that forms a large amount of hard carbides and features simple heat treatment. It is suitable for general cold stamping and shearing tools, especially in conventional cold working scenarios where wear resistance is required.

What is K100 tool steel?
FCS supplies high-carbon, high-chromium cold work tool steel, with BÖHLER K100 referenced for technical comparison only; the material offered is not original BÖHLER K100.K100 Tool Steel is a high-carbon and high-chromium cold working tool steel, and it belongs to the oil-quenched steel type. It features extremely high wear resistance, good hardenability and dimensional stability, and is widely used in the manufacture of molds and tools with high requirements for impact resistance and friction loss.It is usually supplied in annealed state, which is convenient for mechanical processing. After heat treatment, it can achieve high hardness (about 58 to 62 HRC), making it a very cost-effective material choice in the field of cold working dies.
