Our foundry has successfully shipped the first batch of high manganese steel crusher jaw plates and bowl liners to a major iron mine in Western Australia. This milestone marks our entry into the Australian mining market, which demands the highest standards of wear resistance, impact toughness, and product consistency for comminution equipment.
The shipment includes 48 pieces of jaw plates in three different profiles to suit various primary crushing stages, along with 32 sets of bowl liners and mantle combinations for secondary and tertiary cone crushers. All components were cast from premium grade high manganese steel conforming to ASTM A128, with a nominal manganese content of 12 to 14 percent. This alloy is renowned for its exceptional work hardening behavior. Under the high impact forces generated during iron ore crushing, the surface of these castings rapidly hardens from approximately 220 Brinell to over 500 Brinell while maintaining a tough, ductile core that resists cracking.
Each casting underwent rigorous quality control before shipment. Chemical composition was verified by optical emission spectrometry, and mechanical properties were confirmed through tensile and impact testing on separately cast test bars. All jaw plates and bowl liners were subjected to dimensional inspection using 3D scanning to ensure perfect fitment with the customer's existing crusher models. Surface hardness profiles were measured at multiple locations to guarantee uniform work hardening response. The castings were then finished with our new robotic grinding cell to remove parting lines and sharp edges, ensuring safe handling during installation.
The Australian customer conducted a pre shipment audit of our facility and approved our quality management system, including heat treatment records and material traceability documentation. According to the customer's procurement manager, previous suppliers experienced inconsistent wear life and premature cracking. Our trial batch of high manganese steel castings has been engineered to provide a wear life target of at least 5000 hours for jaw plates and 4500 hours for bowl liners under the mine's typical operating conditions.
With this first shipment successfully delivered, we have secured a framework agreement for regular monthly shipments over the next twelve months. We look forward to supporting the Australian iron ore sector with reliable, high performance crusher wear parts that reduce downtime and lower cost per ton.
