摘要

Stainless steel is the most widely utilized material in various process-based sectors because of its remarkable properties such as resistance to corrosion, better performance and excellent mechanical strength. However, it is prone to acidic corrosive attacks due to various environmental conditions. The paper provides a detailed comparative assessment of corrosion behaviour of stainless steel in various concentrations of acidic environments such as sulphuric acid (H2SO4), nitric acid (HNO3), hydrochloric acid (HCl), etc. The distinctive features of various methods such as cathodic protection, selective alloying, coatings, and surface treatment drawn from the latest published literature are discussed, and suggest that the adaptation of these methods provides the potential to enhance corrosion protection in industrial environment. In nut shell, this review can be used by future researchers for different insights regarding the corrosion mitigation and to facilitate their translation into diverse industry applications.
