Often-overlooked duplex stainless steels better for corrosion resistance

Duplex stainless steels, which have a higher chromium content and lower nickel content, are more resistant to pitting and can withstand higher temperatures, which make them a viable solution to unique applications that have a higher likelihood of pitting, says Chemical Corrosion Services consultant Simon Norton.

Speaking during a webinar hosted by Creamer Media on the Essentials of Stainless Steel, held on August 26, he pointed out that stainless steels are a family of passive alloys that contain chromium and form a passive top or chrome oxide layer.
