UNS S32760 F60 Duplex Steel Plate EN 1.4501 Stainless Steel Plate
12*2000*6000mm
UNS S32760 is a super duplex grade with a ferritic-austenitic
microstructure designed for service in aggressive
chloride-containing environments and has additions of W and Cu
compared to UNS S32750. It has good resistance to localized
corrosion and stress corrosion cracking in combination, with high
mechanical strength. The super duplex microstructure has the high
strength of the ferritic grades whilst retaining the corrosion
resistance of the austenitic grades. UNS S32760 also has
outstanding resistance against sulphide-stress corrosion cracking
in sour-gas environments, and high impact strength, even when
welded, UNS S32760 presents only slightly lower impact strength.
UNS S32760 Chemical Composition
The chemical composition of S32760 contains 24-26% chromium, 6-8%
nickel, and 3-4% molybdenum as well as copper, tungsten, and
nitrogen alloy, UNS S32760 is a highly alloyed super duplex
stainless steel with high PREN for use in aggressive environments.

Corrosion Resistance
Alloy S32760 provides excellent corrosion resistance and strength
properties. In comparison with UNS S32205, SUS 329J3L, and SUS
329J4L (NAS 64), it offers superior localized corrosion resistance
and thus is suitable for use in chemical plants, seawater
desalination plants, and similar severe environments.
Welding
Various welding methods are applicable in the same manner as with
the standard austenitic stainless steels, including shielded metal
arc welding, TIG welding, and plasma welding. The use of welding
electrodes for UNS S32760 is recommended. Preheating and
post-heating are not necessary. In welding, the interpass
temperature should be no more than 100℃ to prevent the formation of
intermetallic compounds.
Heat Treatment
Duplex stainless steel cannot be hardened by heat treatment. They
can however be work-hardened.
Solution treatment or annealing can be done by rapid cooling after
heating to around 1100°C.
Disadvantages of UNS S32760
Firstly, the higher price of UNS S32760 is due to its exceptional
properties such as superior corrosion resistance and high strength.
This material is typically costly and not suitable for large-scale
use in cost-sensitive applications.
Secondly, UNS S32760 contains a variety of alloying elements, such
as molybdenum, which may lead to an elemental imbalance if its
alloying composition is not reasonably adjusted, thus reducing its
corrosion resistance. Therefore, special attention needs to be paid
to the balance of alloying elements during use.
Finally, UNS S32760 is susceptible to localized corrosion in
chloride-containing environments. Although it performs well in most
environments, special care needs to be taken when using it in
chloride environments to avoid localized corrosion.
