O2｜1.2842｜9Mn2V

O2 steel, as a typical oil quenched die steel, exhibits superior hardness and wear resistance as its core characteristics. After standardized heat treatment, the hardness of O2 steel remains stable in the range of 58-62 HRC, with high carbon content (1.55-1.70%) forming uniform carbides with chromium elements, significantly improving the material's wear resistance, especially suitable for high load stamping scenarios. O2 steel is widely used in the manufacturing of small punching dies, gauges, and machine tool screws.

1.2842 steel is suitable for manufacturing precision measuring tools, templates, small stamping/cold pressing/carving/cutting molds, and machine tool screws and other structural components. 1.2842 steel is also commonly used to manufacture cold stamping dies and tools with large cross-sections, complex shapes, and heavy working conditions, such as stamping dies, trimming dies, grinding dies, steel plate deep drawing dies, circular saws, standard tools and gauges, rolling dies, etc.
