Forgings for Cones of drill Bit are in the scope of Welong Supply Chain. The raw material for the forgings can be customized as per client’s requirements. For example, the steel grade AISI 9310, according to US standard SAE J1249-2008, can be used as the raw material for the forgings. AISI 9310 steel is the American standard SAE/AISI designation and belongs to the category of high-quality low-alloy high-strength steel. It corresponds to the Chinese standard grade 10CrNi3Mo in terms of chemical composition. AISI 9310 steel shows high strength, toughness, hardness, and fatigue strength, making it primarily used for aerospace gears, turbine blade gears, and military components. By undergoing carburizing heat treatment, AISI 9310 steel can acquire excellent mechanical properties, making it suitable for gears, shafts, worms, bolts, and studs that operate under high load conditions. Generally, forged rounds are delivered in the form of hot-forged and annealed.
For the requirements of cones forgings, the usual manufacturing process includes die forging, rough machining, and normalizing. Additional processing can also be carried out according to customer requirements. When using AISI9310 material, it must comply with the composition requirements and specifications outlined in SAE J1249-2008 standard. The normalizing requirement for cones is that the temperature should reach 954.44℃. The normalization process entails placing the forging into a furnace after the temperature inside reaches 350℃. The furnace is then heated up to 954.44℃±10℃ and maintained at this temperature for 2 hours before being air-cooled. After completion of normalizing, a complete normalizing curve should be provided. Further machining of the cones is performed based on customer drawings. The applicable machining tolerances are in accordance with ISO 2768—MK standard.
