Sandvik has won a contract to supply seamless coiled tubing made from its SAF 2507®super duplex stainless steel to a geothermal plant in Central America.
Most nuclear power plants in the world use sea water as its cooling medium; seawater is the most corrosive medium in the natural environment which are prone to produce pitting for common stainless steel materials.
Sandvik SAF 2507® is a super-duplex (austenitic-ferritic) stainless steel for service in highly corrosive conditions. The grade is characterized by excellent resistance to stress corrosion cracking (SCC) in chloride-bearing environments, excellent resistance to pitting and crevice corrosion, high resistance to general corrosion, very high mechanical strength, physical properties that offer design advantages, high resistance to erosion corrosion and corrosion fatigue and good weldability.
In 2014, several heat exchangers at an Egyptian Propane Dehydrogenation plant failed unexpectedly and caused a production shutdown.
