UNS S32750 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, with the balance being iron.

S32750. Alloy. 2507. Description. 1.4410 / Alloy 2507 is a SUPER-DUPLEX stainless steel. Special properties. Exceptional strength and corrosion resistance. Excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. Chemical Composition.

Super Duplex UNS S32750 is the most common super duplex grade in the market. Designed for service in aggressive chloride-containing environments. By using 1.4410 (UNS S32750 – F53 – 2507) you get a stainless super duplex steel that has extremely high resistance to various types of corrosion. It has good weldability and can be welded by several methods. The steel is widely used e.g. for propeller shafts, pump parts and piston rods. The steel grade 1.4410 ( also called UNS S32750 , F53 and This paper presents an overview of duplex stainless steels (DSS) with particular emphasis on super DSS, i.e.

Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen content results in excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure By using 1.4410 (UNS S32750 – F53 – 2507) you get a stainless super duplex steel that has extremely high resistance to various types of corrosion. It has good weldability and can be welded by several methods. The steel is widely used e.g.

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".

The UNS designation for SAF 2507 is S32750 and the EN steel no. is 1.4410. 2021-03-05 · This datasheet is only valid for Sandvik materials. 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. As a super duplex stainless steel, the SAF 2507 combines the desirable aspects of both austenitic and ferritic grades.

the austenitic grades Sandvik 2RK65™ or Sanicro® 28, or the super-duplex grade Sandvik SAF 2507®. Pitting corrosion: The pitting resistance of a steel is determined primarily by its chromium and molybdenum contents, but also by its nitrogen content and its slag composition and content.
