Generic Family:
Steel - Wrought - Stainless - Austenitic
•
Supplied by:
Sandvik Materials Technology
Sandvik 2RE69 is a fully austenitic stainless steel with extra low carbon and impurity contents. The grade is characterized by:
Sandvik 2RE69 has been developed primarily to cope with the severe corrosive conditions existing in the urea industry. The longest service life is so far 35 years, which confirms the optimal properties for the grade Sandvik 2RE69 in urea strippers.
Applications
Sandvik 2RE69 is used successfully in all critical high-pressure units of modern urea processes, such as:
Sandvik 2RE69 has also found extensive use in other corrosive environments in fertilizer plants, such as:
- Excellent resistance to corrosion in ammonium carbamate and nitric acid
- Excellent resistance to intergranular corrosion
- High resistance to pitting and crevice corrosion
- Good weldability
