Experienced Heavy Forging Supplier for Mining & Construction

Why Choose a Specialized Heavy Forging Supplier for Mining & Construction

Mining and construction equipment demands extreme durability, high load capacity, and wear resistance under harsh conditions (shock, vibration, abrasion, heavy impact). An experienced heavy forging supplier delivers:
  • High-strength material solutions: ASTM alloy steel (4140/4340/F22), carbon steel, and custom grades
  • Large & complex forging capability: Open-die/closed-die forgings up to 50–200 tons
  • Full in-house process: Forging, heat treatment (QT/normalization/annealing), rough & finish machining
  • Strict quality control: ASTM-compliant NDT (UT/MT/PT), mechanical testing, and material traceability
  • Proven track record: Decades of serving global mining/construction OEMs and heavy machinery manufacturers
