What's the difference between duplex stainless steel and plain steel?
Ordinary steel usually refers to ordinary carbon steel and duplex stainless steel with austenite and ferrite stainless steel body, compared with ferrite, the plasticity and toughness are higher, no room temperature brittleness, intergranular corrosion resistance and welding performance was significantly improved, while also maintaining a ferritic stainless steel 475 C the brittleness and high thermal conductivity, superplasticity etc..
Compared with austenitic stainless steel, it has high strength, good intergranular corrosion resistance and chloride stress corrosion resistance. Duplex stainless steel has excellent corrosion resistance and is also a stainless steel.
