Duplex stainless steel refers to ferrite and austenite each
accounting for about 50%. Generally, the content of less phase also
needs to reach at least 30% of stainless steel. In the case of low
C content, the Cr content is 18% to 28%, and the Ni content is 3%
to 10%. Some steels also contain alloying elements such as Mo, Cu,
Nb, Ti, and N.
This type of steel has the characteristics of both austenite and
ferritic stainless steel. Compared with ferrite, it has higher
plasticity and toughness, no room temperature brittleness,
significantly improved intergranular corrosion resistance and
welding performance, while maintaining iron Element stainless steel
has 475 ° C brittleness, high thermal conductivity, and
superplasticity. Compared with austenitic stainless steel, it has
higher strength and significantly improved resistance to
intergranular corrosion and chloride stress corrosion. Duplex
stainless steel has excellent pitting resistance and is also a
nickel-saving stainless steel.
