Corrosion Resistance of Stainless Steels - IMOACorrosion resistance of stainless steels Corrosion in concrete (corrosion problems are not limited to outside surfaces !) Stainless steel provides both strength and corrosion resistance inside the concrete, providing a long, maintenance-free service life of the structure. Corrosion of unprotected carbon steel occurs even inside reinforced

Corrosion Resistant Metals Materials Selection Guide

In all stainless steels, chromium and nickel are critical for corrosion resistance and ductility. The addition of >10% chromium transforms steel into stainless steel, creating an adherent and invisible oxide layer that is chromium-rich. This oxide layer forms Corrosion resistance of duplex stainless steelsOn the other hand Duplex stainless steel 2507 and 2205 provide adequate service in the aq. HCl. Pitting is generally not an issue however crevice attack should be prevented. Nitric Acid. In the powerful oxidizing chemicals including nitric acid, commonly used molybdenum-free steels offer better corrosion resistance than molybdenum based steels.
