Question 1

What is Duplex Steel Plate S31803?

Accepted Answer

Duplex Steel Plate S31803, also known as Duplex 2205, is a high-strength, corrosion-resistant stainless steel plate with a ferritic-austenitic microstructure. It offers excellent resistance to stress corrosion cracking, pitting, and crevice corrosion, making it ideal for marine, oil & gas, and industrial applications.

Question 2

Where are Duplex Steel Plates S31803 commonly used?

Accepted Answer

These plates are widely used in offshore platforms, pressure vessels, heat exchangers, chemical processing plants, desalination units, and structural components, where high strength and corrosion resistance are required.

Question 3

How does Duplex Steel S31803 compare to standard stainless steel?

Accepted Answer

Duplex S31803 has twice the strength of 304 and 316 stainless steel, along with better resistance to chloride-induced stress corrosion cracking, making it more durable for demanding applications.
