Duplex steel S31050 sheet plate

UNS S31050 stainless steel  is a austenitic stainless steel,  the nitrogen helps to stabilize and strengthen the austenitic phase, 310 MoLN gives excellent corrosion-resistance in urea carbamate environments such as high-pressure strippers. The unique duplex microstructure makes duplex UNS S31050 plate an attractive alternative to traditional stainless steels, especially in harsh environments where other materials may fail.

Duplex steel UNS S31050 310 MoLN Plate Chemical Composition

310 MoLN Duplex steel Plate Mechanical properties

UNS S31050 310moln stainless steel characteritics:

• Excellent resistance to corrosion in ammonium carbamate and nitric acid

• Excellent resistance to intergranular corrosion

• High resistance to pitting and crevice corrosion

• Good weldability

General corrosion

• S31050 was originally developed for stripper tubes used in the production of urea.

• S31050 has excellent corrosion resistance in urea/carbamate solutions at high pressures and temperatures.

• S31050 is also highly resistant to inorganic acids

Intergranular corrosion

• 310moln is highly resistant to intergranular corrosion after welding.

Pitting and crevice corrosion

• UNS S31050 has very good resistance to pitting, and is also far more resistant to crevice corrosion than ASTM 316L.

Stress corrosion cracking (SCC)

• Conventional  austenitic  stainless  steels of  type  ASTM 304 and  316 are  susceptible  to  stress  corrosion  cracking (SCC) inchloride- bearing  solutions  at temperatures exceeding about 60°C (140°F). The higher nickel content makes S31050 slightlymore resistant

Duplex steel UNS S31050 310MoLN plate is a high-strength and corrosion-resistant material that delivers excellent mechanical and physical properties. It is widely used in many industries due to its versatility, durability, and cost-effectiveness.
