In July 2026, Shanghai Hangbo Alloy Group Co., Ltd. completed installation and commissioning of a new 500-ton CNC forging press now in production. Working alongside the existing 100-ton press and ring rolling mill, it lifts overall capacity for large alloy forgings by about 60%.
New capability
| Item | Value |
|---|---|
| Maximum single forging weight | 8000 kg |
| Maximum ring outer diameter | 3500 mm |
| Materials | Superalloys, nickel alloys, titanium, stainless and precision alloys |
| Processes | Open die, closed die, ring rolling |
| Heat treatment | Solution, normalising, quench and temper, ageing — ±5 °C |
Value for customers
- Large turbine discs, rings and shells can be formed in one piece, eliminating assembly welds
- Controlled forging ratio improves structural density and property consistency
- Lead time for large forgings cut by about 30%
- Less subcontracting means better control of quality and delivery
Supporting inspection
Every forging batch is delivered with complete heat-number records: melt chemistry, forging parameters, heat treatment charts, mechanical properties and NDT results. EN 10204 3.1 certificates, with independent third-party inspection available on request.
Frequently asked questions
What is the maximum forging size Hangbo can produce?
Current capability is 8000 kg per piece and 3500 mm maximum ring outer diameter, using open die, closed die and ring rolling across superalloys, nickel alloys, titanium, stainless steel and precision alloys.
What is the lead time for large forgings?
Typically 4–8 weeks from order confirmation depending on material, size, heat treatment and testing requirements. Since the 500-ton press was commissioned, lead times for these products have shortened by about 30%.
