Therefore, Alleima has expanded its advanced materials portfolio for urea with SAF 2906, a super duplex stainless steel designed to withstand the most corrosive environments.
About Alleima and Its Industry Applications
Alleima, a global manufacturer of high value-added products in advanced stainless steels and special alloys as well as solutions for industrial heating, offers products for a variety of industries and applications.
SAF 2906: Engineered for Extreme Conditions
SAF 2906 has been engineered to meet the stringent demands of the urea industry, requiring exceptional durability and reliability. Originally developed for the urea synthesis process, the grade can withstand extremely high pressures and temperatures. Its superior corrosion resistance against low-oxygen carbamate solutions ensures enhanced plant safety and productivity by preventing corrosion-related issues. Equipment failure resulting from corrosion can lead to costly downtime and maintenance. Selecting the most suitable material for the purpose is crucial for ensuring the longevity and efficiency of urea production plants.
Key Advantages of SAF 2906
- Excellent corrosion resistance to carbamate solutions: SAF 2906 is optimised for superior corrosion resistance against carbamate solutions with low oxygen content, thereby enhancing both plant safety and productivity.
- Very high strength: With a yield strength nearly three times that of conventional austenitic stainless steels - SAF 2906 gives design advantages and allows for lighter constructions.
- Excellent pitting and stress corrosion cracking (SCC) resistance: SAF 2906 has a carefully balanced composition, which gives the material high resistance to chloride-rich environments, ensuring long-term reliability.
- Enhanced fabrication & weldability
