Product Description
EN ISO 4957 C105W1 / 1.1545 Tool Steel - Cold Work Steel
1: DIN C105W1 Steel Introduction
C105W1 is a high-carbon steel material characterized by excellent wear resistance and high hardness. Typically supplied in cold-rolled or hot-rolled conditions, it is suitable for manufacturing components demanding high wear resistance, such as cutting tools, molds, bearing rings, and high-strength mechanical parts. After appropriate heat treatment, C105W1 achieves a uniform hardened layer and good dimensional stability, making it widely used in industrial tooling and precision machinery manufacturing.

6: Goods available in China
If you want to purchase C105W1 steel from China, you can find the stocks from China market for both flat bar and round bar forms. However, the available stock quantities and specifications are often limited. This is because the domestic market predominantly uses T10A or other more common carbon tool steels for similar applications. If you can accept T10A as a substitute for C105W1 material, it can significantly improve availability and save cost.
