2021-03-05 · SAF 2507 ® U-bend specimens exposed for 1000 hours in hot brine (108°C, 226°F, 25% NaCl) showed no cracking. The threshold stress for SAF 2507 ® in 40% CaCl 2 at 100 °C (210 °F) and pH = 6.5 is above 90% of the tensile strength for both parent metal and welded joints (TIG-welded with Sandvik 25.10.4.L or MMA-welded with Sandvik 25.10.4.LR). SAF 2507, also known as Sandvik SAF 2507, is a Sandvik-owned trademark for a 25Cr duplex (ferritic-austenitic) stainless steel.The nominal chemical composition of SAF 2507 is 25% Chromium, 7% Nickel, 4% Molybdenum and other alloying elements such as Nitrogen and Manganese. 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.

Vid stränggjutning av det duplexa rostfria stålet SAF 2507 har varmsprickor observerats av Sandvik Materials Technology i form av längsgående hörnsprickor i det första ämnet som stränggjuts. SAF 2205 innehåller samma legeringsämnen som SAF 2507, dock med någon skillnad i koncentrationen av elementen.
