Duplex stainless steel


Duplex Stainless Steel (Duplex Stainless Steel, hereinafter referred to as DSS), refers to the ferrite and austenite each account for about 50%, and the content of general is a youthful appearance also need to achieve at least 3 o % of the Stainless Steel.


Duplex stainless steel corrosion resistance:


Point corrosion (critical point corrosion temperature CPT, point corrosion weight loss, point corrosion potential)


Gap corrosion (critical gap corrosion temperature CCT, gap corrosion weight loss)


Stress corrosion test (boiling magnesium chloride, hydrogen sulfide stress corrosion)
