Alleima's New Super Duplex Steel Fights Urea Plant Corrosion
Swedish specialty steelmaker Alleima has unveiled SAF 2906 – a super duplex stainless steel engineered specifically to withstand urea production’s brutal conditions.
This innovation targets a critical industry pain point: equipment failure in high-pressure synthesis sections.
Why Urea Plants Need This
Urea manufacturing creates one of chemistry’s most aggressive environments:
Extremely corrosive carbamate solutions
200+ bar pressure vessels
180-200°C operating temperatures
Standard materials often crack or corrode prematurely, causing:
Unplanned shutdowns (costing $500k+/day)
Safety hazards from leaks
Frequent component replacements
SAF 2906's Performance Edge
| Feature | Benefit |
| Stress corrosion resistance | Survives carbamate attack 3X longer |
| High-pressure integrity | Maintains strength at 250°C+ |
| Welding stability | Fewer heat-affected zone failures |
Real-Impact Savings
Early adopters report:
40% reduction in heat exchanger replacements
300+ extra operating hours/year
Maintenance cost cuts up to 65%
For urea producers battling downtime, this isn’t just better steel – it’s profit protection.
