Nandishwar Steel has an extensive inventory of Duplex LDX 2101®, 2304, 2205 and 2507, 31803, 32750, 32760
duplex stainless steel plate and sheets products available to satisfy your challenging corrosion and
high strength requirements.
Duplex stainless steel plate contains relatively high
levels of chromium (between 18% and 28%) and low to moderate amounts of nickel (between 1.5% and 8%).
The high corrosion resistance and excellent mechanical properties of duplex stainless steels can be
attributed to their chemical composition and balanced (duplex) microstructure of approximately equal
volume percentages of ferrite and austenite.
LDX 2101® is a low nickel, nitrogen-enhanced lean duplex
stainless steel with corrosion resistance similar to 304 but with much higher mechanical strength. This
enables it to be used in thinner cross-sections which provide cost savings to the end user. Alloys 2304
and 2205/31803 are the most common grades. They both exhibit outstanding resistance to chloride
stress-corrosion cracking.
“Super” duplex grades have enhanced pitting and crevice
corrosion resistance when compared with 300-series austenitic stainless steels or conventional duplex
alloys. This can be attributed to the enhanced levels of chromium, molybdenum and nitrogen found in
these materials. Alloy 2507 is the most common “super” duplex grade.
What are the advantages of the duplex steel sheet and plates?
Duplex steel sheets and plates have several advantages, making them a popular choice for architects and
builders alike. This material has high strength and stress corrosion cracking resistance and is
exceptionally durable and suitable for use in both indoor and outdoor environments. Additionally, duplex
steel sheets and plates provide excellent weldability compared to traditional stainless steels, allowing
for fast installation times at job site locations. Plus, their superior corrosion resistance extends the
lifespan of these materials far beyond the typical stainless steel-making them an ideal cost-effective
solution for many applications. Ultimately, duplex steel sheets and plates are an efficient option for
recognizing significant savings over time.
What is a Super Duplex Steel sheet used for?
Super Duplex Steel sheet is primarily used in applications requiring excellent corrosion resistance
combined with high resistance to stress corrosion cracking. This steel has been developed as an upgrade
to standard austenitic stainless steel. It provides a combination of strength and corrosion resistance
that can enable the user to reduce downtime and save money by reducing the frequency or intensity of
maintenance or repairs caused by corrosion. Super Duplex Steel sheet offers numerous benefits regarding
construction, engineering and fabrication needs; its properties, such as increased strength and
long-term durability, have made it popular for large and small projects. In addition, its dual nature
makes this steel suitable for marine environments, pipes and bridge structures – whatever the
application, it is certain that Super Duplex Steel can be relied upon get the job done.
