ASTM A789 ASME SA 789 SAF2507 UNS S32750 (EN 10216 – 5 1.4410) Stainless Steel is super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for

ASTM A789 ASME SA 789 SAF2507 UNS S32750 (EN 10216 - 5 1.4410) Stainless Steel is super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.

Figure 5 shows the isocorrosion diagram for SAF™ 2205 in hydrochloric acid. Impurities that increase corrosivity are often present in process solutions of acids. If there is a risk of active corrosion, higher alloyed stainless steels should be chosen, e.g. the austenitic grades Alleima ® 2RK65 or Sanicro ® 28, or the super-duplex grade SAF™ 2507.

Description 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

SAF 2507 ® SAF 2507 is a high alloy super-duplex steel for service in extremely corrosive conditions. Developed mainly for applications exposed to high stresses in chlo-ride-containing environments like seawater, it contains high amounts of chromium, molybdenum and nitrogen. SAF 2205 ® SAF 2205 is a medium

2507 super duplex machinability is poor. In order to improve the poor machinability of 2507 super duplex, high content of ferrite (above 60%) is used. The pitiable machinability is generally caused due to elevated tensile strength and yield strength. 2507 super duplex can tolerate organic and inorganic acids and it has a high resistance to general corrosion, chloride pitting and stress.

Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard. SAF 2507®, with a maximum hardness of 32 HRC, solution annealed and rapidly cooled, according to NACE MR0103, is suitable for use in sour

Duplex alloy 2507 (S32750) is a widely used super duplex stainless steel. Many international equivalents are available commercially including EN/DIN 1.4410 (X2CrNiMoN25-7-4), JIS SUS 329 J4L, China's GB 022Cr25Ni7Mo4N, KS STS 329 J4L, as well as AF 2507, UR 2507, NAS 74N, SAF 2507.

2022/5/2 · So, when it came to selecting umbilical tu for the two fields, SAF 2507® high-alloy super duplex stainless steel from Materials Technology was a stand-out choice. A super-duplex stainless steel, SAF 2507® has a high PRE (pitting resistance equivalent) value of at least 42.5 for tube and pipe.

In SAF™ 2507 the PRE value is equal in both phases, which has been achieved by a careful balance of the elements. The minimum PRE value for SAF™ 2507 seamless tubes is 42.5. This is significantly higher than e.g. the PRE values for other duplex stainless steels of the 25Cr type which are not super-duplex.

Super Duplex 2507®, is very similar to UNS S31803 2205® Duplex. The difference between the two is the contents of chromium and nitrogen are higher in the 2507® which in turn creates higher corrosion resistance as well as a longer lifespan. 2507® is composed of between 24% to 26% chromium, 6% to 8% nickel, 3% molybdenum, and 1.2% manganese
