Super Duplex Steel Sheets / Plates / Coils | Grade 2507 (UNS S32750)

Super Duplex Steel 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 2507 Super Duplex Steel (S32750):

Chromium:24-26%
Nickel:6–8%
Molybdenum:3-5%
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:0.030% max

Super Duplex Steel S32760:

It is mainly used in aggressive environments.S32760 super duplex steel gives excellent strength, corrosion resistance, toughness in various types of acids.It also provides high resistance to strong alkalis and resists corrosion in many non-oxidizing acids.
The chemical compositions of S32750 and S32760 are almost similar except S32760 contains slightly more copper & tungsten. The copper content gives excellent resistance to corrosion acids like sulfuric & hydrochloric acid.

Typical Composition of Super Duplex Steel (S32760):

Chromium:24-26%
Nickel:6–8%
Molybdenum:3-4%
Manganese:1% max
Silicon:1% max
Tungsten:0.5-1.0%
Copper:0.5-1.0%
Nitrogen:0.2-0.3%
Phosphorus:0.03% max
Sulfur:0.010% max
Carbon:0.030% max
