Super duplex stainless steel bars have higher chromium and molybdenum compare to Duplex which makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid. Super Duplex steel also shows good strength and ability to work at low temperature. Additionally, they show toughness and corrosion resistance features.
