O1/1.2510/9CrWMn is a manganese-chromium-tungsten cold work tool steel supplied by Wuhan Jin Xingqiang Mould Steel Co., Ltd. as vacuum-degassed fine-grain bar stock. The grade delivers high hardness after heat treatment, with carbon content between 0.85 and 0.95 percent, chromium at 0.50 to 0.80 percent, and tungsten at 0.70 to 1.20 percent, providing superior wear resistance and dimensional stability for precision tooling applications. Quenching is performed at 800 to 830 degrees Celsius in cold oil, with preheating recommended at 650 to 750 degrees Celsius to reduce crack sensitivity in oil-quenched dies.
The material is supplied in the annealed condition, enabling ease of machining before final hardening. Manganese content of 0.90 to 1.20 percent enhances hardenability, while the alloy’s low sulfur and phosphorus levels (0.030 percent max each) improve toughness and reduce brittleness. Typical industry use includes broaches, filament hammers, gauges, complex cold molds, and precision screws, where minimal distortion during heat treatment is critical. Standard industry practice for this grade includes forging at 1130 to 1150 degrees Celsius, with finishing above 800 to 850 degrees Celsius to ensure uniform grain structure.
This steel is widely adopted in industrial tooling supply chains for cutting tools, dies, and measuring instruments due to its ability to retain hardness and resist abrasion under high-stress conditions. Buyers often source this grade for applications requiring tight tolerances and long service life, such as punches and cold-work dies. The supplier offers the material as bar stock, with delivery in annealed condition unless otherwise specified by the customer.

Before ordering O1/1.2510/9CrWMn cold work tool steel from Wuhan Jin Xingqiang Mould Steel Co., Ltd., verify the exact chemical composition and heat treatment history to ensure it meets your tooling requirements. Confirm the material’s delivery condition, as annealed stock may require additional processing to achieve desired hardness and wear resistance. Request mill test certificates to validate the alloy’s compliance with industry standards for cold work tool steels.
Logistics details such as lead time, packaging, and shipping terms should be clarified directly with the supplier. Wuhan Jin Xingqiang Mould Steel Co., Ltd. typically supplies bar stock, but packaging options and Incoterms (e.g., FOB Wuhan) must be agreed upon. Confirm whether the supplier can accommodate specific dimensions or surface finishes, as these may impact transportation and handling costs.
Quality checks should include hardness testing (e.g., Rockwell C scale) and microscopic examination for grain structure uniformity. Inspection of the material’s surface for defects or decarburization is also recommended. Request documentation such as material test reports (MTRs) and heat treatment records to ensure traceability and compliance with your quality standards. For critical applications, consider third-party inspection before shipment.
