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 when chromium in the alloy reacts with oxygen in ambient air.

Corrosion of Stainless Steels IspatGuru

Erosion-corrosion is the corrosion of a steel or alloy which can be accelerated when there is an abrasive removal of the protective oxide layer. This form of attack is especially significant when the thickness of the oxide layer is an important factor in determining corrosion resistance. Corrosion-Resistant Alloy - an overview ScienceDirect TopicsCorrosion-resistant alloys (CRAs) The term corrosion-resistant alloy (CRA) is commonly used to cover all metals that are, to some degree, capable of resisting corrosion as compared with carbon steel. This resistivity to corrosion is not universal as it varies to a large degree on the specific corrosion environment and depends on the alloying Corrosion of Alloy Steels IspatGuru

DESIGN GUIDELINES FOR THE SELECTION AND USE OF

Stainless steels are iron-base alloys containing 10.5% or more chro-mium. They have been used for many industrial, architectural, chemical, and consumer applications for over a half century. Currently there are being marketed a number of stainless steels originally recognized by the American Iron and Steel Institute (AISI) as standard alloys. Effect of Sb on the Corrosion Behavior of Low-Alloy Steels Corrosion of Alloy Steels IspatGuruThe types of corrosion that low-alloy structural steels experience in a marine environment mainly include uniform corrosion, pitting and stress corrosion. However, there is still no systematic theoretical support for the evaluation of corrosion types and the mechanism of low-alloy steel corrosion in marine environments (Ref 6,7,8).
