1.2379 Round bar steel
Carbon Steel Rod Products Description
1.2379 round metal bar is a high carbon and high chromium cold working die steel, which can be used to produce cold working dies with large cross-section, complex shape, high impact force and high wear resistance. At the same time, 1.2379 round bar is also called D2 steel round bar.
1.2379 steel rod bar has high NMenability, good high temperature oxidation resistance, and good corrosion resistance after quenching and polishing.
1.2379 round metal stock is suitable for manufacturing cold working dies with high precision, long life and high wear resistance, such as precision stamping dies, cold extrusion dies, deep drawing dies, blanking dies, embossing dies and cold forging dies.
