What is Super Duplex Steel S32750?

Super Duplex Steel UNS S32750, also known as 2507 duplex steel. It also has other tags: Grade S32750, DIN 1.4410, F53. Super Duplex stainless S32750 like Duplex Steel, is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades. The main difference is that Super Duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance than standard duplex grades.

General Properties of Super Duplex Steel UNS32750

UNS S32750 super duplex stainless steel based on 25% chromium, 7% nickel and significant additions of molybdenum, manganese and nitrogen. Improved corrosion resistance in comparison to Duplex Steel and greater tensile and yield strength. The super duplex stainless steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. The high chromium, molybdenum, and nickel levels provide excellent resistance to pitting, crevice, and general corrosion.


Super Duplex Alloy UNS S32750 (F53 / 1.4410 / Alloy 32750 / Alloy 2507) combines the most desirable characteristics of both ferritic and austenitic steels. With outstanding resistance to pitting and crevice corrosion in seawater and other chloride containing environments due to its high chromium, molybdenum, and nitrogen level, with Critical Pitting Temperature exceeding 50°C.UNS S32750 is characterized by:

Excellent resistance to chloride stress corrosion cracking

Pitting Resistance Equivalent number (PREN) of >41

Good workability and weldability

High mechanical strength

High resistance to abrasion, erosion and cavitation erosion


Duplex 2507 possesses excellent mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy. The resulting savings in weight can dramatically reduce the overall cost of fabrication. The mechanical properties of S32750 are shown in the table below:
