Instruction of Super Duplex Steel Uns S32750 Sheets And Plates

Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.

Features of Super Duplex Steel Uns S32750 Sheets And Plates

1. Super Duplex Steel Uns S32750 Sheets And Plates General Corossion:

  • high chromium and molybdenum content of 2507 makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid.
  • provides excellent resistance to inorganic acids, especially those containing chlorides.
  •  can be used in dilute hydrochloric acid.
  • Pitting need not be a risk in the zone below the borderline in this figure, but crevices must be avoided.

2. Super Duplex Steel Uns S32750 Sheets And Plates Intergranural Corossion:

  • Low carbon content greatly lowers the risk of carbide precipitation at the grain boundaries during heat treatment.
  • Is highly resistant to carbide-related intergranular corrosion.

3. Super Duplex Steel Uns S32750 Sheets And Plates Stress Corossion Cracking:

  • Duplex structure of 2507 provides excellent resistance to chloride stress corrosion cracking (SCC).
  • Superior to 2205 in corrosion resistance and strength.
  • 2507 is especially useful in offshore oil and gas applications and in wells with either naturally high brine levels or where brine has been injected to enhance recovery.

4. Super Duplex Steel Uns S32750 Sheets And Plates Heat Treatment:

2507 should be solution annealed and quenched after either hot or cold forming. Solution annealing should be done at a minimum of 1925°F. Annealing should be followed immediately by a rapid air or water quench. To obtain maximum corrosion resistance, heat treated products should be pickled and rinsed.

 

Marking and packaging of Super Duplex Steel Uns S32750 Sheets And Plates

The packaging of our products (eg. weathered corrugated steel, weathering corrugated steel,corten steel columnl,hot rolled stainless steel plate) ensures that they will not be damaged during transport. For export purposes, the usual export packaging is done in wooden crates or crates. All hr sheet metal, plates and coils are marked with a logo (company mark), grade, size and batch number. On request, we can customise the marking on the product,such as spcc cold rolled steel.
