Duplex steels are prepared of the varied microstructure of austenite and ferrite; generally, it is made of 50/50 mix, however, in commercial alloys steel, the ratio may vary to 40/60. Duplex stainless steel has around two time’s greater strength as compared to austenitic stainless steels and also improved resistance mainly to pitting corrosion and stress corrosion cracking.

They contain high chromium 19 to 32% and molybdenum up to 5%. They have lower nickel content compared austenitic stainless steels. They are generally cost effective due to lower alloy content than similar performing austenitic steels.

Duplex Steel Sheets / Plates /Coils (Alloy 2205):

Its a nitrogen alloyed duplex steel containing 22% chromium, 3 % molybdenum & 5 to 6 % Nickel and has corrosion resistance similar to standard austenitic steel & high alloyed ferrite steel.It also has high thermal conductivity & low thermal expansion as compared to austenitic steel.

Typical Composition Of Duplex Steel:
Chromium:22-23%
Nickel:4.5–6.5%
Molybdenum:3-3.50%
Manganese:2% max
Silicon:1% max
Nitrogen:0.14-0.20%
Phosphorus:0.030% max
Sulfur:0.020% max
Carbon:0.030% max

Super Duplex Steel Sheets / Plates / Coils (Alloy 2507):

It consists of 25% chromium, 4 % molybdenum & 7% Nickel.It has corrosion resistance at par with high performing austenite steel.Due to its high alloy content it provide superior resistance to general,pitting & crevice corrosion.It is highly suitable for applications that require greater strength & excellent corrosion resistance.

Typical Composition Of Super Duplex Steel:
Chromium:24-26%
Nickel:6–8%
Molybdenum:3-4%
Manganese:1.2% max
Silicon:0.8% max
Copper:0.5% max
Nitrogen:0.2-0.3%
Phosphorus:0.035% max
Sulfur:0.020% max
Carbon:0.020% max
