Comparative test Extensive testing in a variety of machining applications has shown that SAF 2507 ® bars provided better machinability than the nearest competitor material with 23% better tool life and overall savings on all machined components: 168 holes drilled before tool failure, compared to 135 for competitor material 168 holes tapped, compared to 112 Tool wear less than 0.3 mm for all 2021-03-05 · 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 In SAF 2507 ® the PRE-value is equal in both phases, which has been achieved by a careful balancing of the elements. The minimum PRE-value for SAF 2507 ® is 41. This is significantly higher than e.g. the PRE-values for other duplex stainless steels of the 25Cr type which are not "super-duplex". CLI - SAF 2507® has improved corrosion resistance properties when compared to duplex 2205 type materials, or even to URANUS® 47N. It is designed for service in severe corrosive conditions.

Hydrogen Induced Stress Cracking (HISC): Hydrogen Induced Stress Cracking (HISC) is an embrittlement phenomenon which may occur in cathodically protected subsea steel constructions in the presence of high tensile stresses. SS 2328/SAF 2507 Super Duplex. SS 2328/SAF 2507 har hög sträckgräns och är särskilt lämpat för marina förhållanden t.ex. för rörledningar och värmeväxlare inom off-shore industrin. I alla avseenden högre korrisionsresistens än övriga ferrit-austenitiska stål (SS 2324, 2327 och 2377).
