Duplex stainless steels were first manufactured early in the 20th century, but it was the introduction in the 1970s of the argon-oxygen decarburisation (AOD) steel making process and the addition of nitrogen to these steels, that made the alloys stronger, more weldable and more corrosion resistant. Today, duplex stainless steels can be categorised into four main groups, i.e., “lean”, “standard”, “super”, and “hyper” duplex types. These groups cover a range of compositions and properties, but they all have in common a microstructure consisting of roughly equal proportions of austenite and ferrite, high strength, good toughness and good corrosion resistance, especially to stress corrosion cracking (SCC) compared with similar austenitic stainless steels. Moreover, the development of a duplex stainless-steel microstructure requires lower levels of nickel in the composition than for a corresponding austenitic stainless steel with comparable pitting and crevice corrosion resistance, hence they cost less. This makes duplex stainless steels a very versatile and attractive group of alloys both commercially and technically. There are applications where duplex grades can be used as lower cost through-life options, in preference to coated carbon steels, a range of other stainless steels, and in some cases nickel alloys. This cost benefit is further emphasised if the design engineer can use the higher strength of duplex grades to construct vessels and pipework of lower wall thickness than would be the case if an austenitic grade or nickel alloy was being used. Hence, we find duplex stainless steels are widely used in many industries. In this paper their use in three industrial applications is reviewed, namely marine, heat exchangers, and the chemical and process industries. The corrosion resistance in the relevant fluids is discussed and some case histories highlight both successes and potential problems with duplex alloys in these industries. The paper shows how duplex stainless steels can provide cost-effective solutions in corrosive environments, and why they will be a standard corrosion resistant alloy (CRA) for many industries through the 21st century.

“…Almanza et al [47] had also added that the formation of titanium oxide layer helps improved the corrosion of Ti-6Al-4 V alloys. However, Sukanya et al [48] have shown that despite chromium, molybdenum, and nitrogen, stainless steel's atmospheric corrosion is a reality based on alloying element level, surface roughness, surface treatment, and microclimate. The effect of bioaerosols on stainless steel can be devastating, based on the composition of bioaerosols.…”

Despite extensive work on improving atmospheric corrosion resistance in metals, i.e., steel and alloy, the corrosion rate on the metallic surface is higher at some localized geographical area of the globe. Despite the visible successes in recent coating technology in curbing environmental conditions, it is proposed that the recent increase of atmospheric bioaerosols has a significant role in the dissolution of corrosion-resistant coating over a metallic surface. In this review, the science of atmospheric corrosion on metallic materials was reviewed in the light of the chemical and physical composition of atmospheric bioaerosols and aerosols. It was observed that aside from general conditions (i.e., alloying element level, surface roughness, surface treatment, and microclimate), the bioaerosols content is essential for future research in corrosion. It is recommended that further experimental research be carried out to corroborate the science of atmospheric bioaerosols to different forms of corrosion.

“…These exposure tests were continued over a period of 5 years to yield further knowledge about the long‐term corrosion behaviour of these alloys which have not or only seldom been used in such environments. Besides the evaluation of the fundamental corrosion properties particularly the typical processing and surface states occurring in practice should also be considered as they could significantly affect the corrosion resistance …”

Nine different stainless steel alloys were exposed for 5 years under marine environment and their corrosion behaviour was compared and assessed. The investigation of four different surface finishes for all alloys tested further enabled to consider industry-specific features of the surface finish for the material comparison.The results of the exposure tests yield conclusions regarding the influence of alloy composition, surface finish and exposure duration under marine environment. The three duplex stainless steels revealed excellent corrosion resistance even in case of crevices during the 5 years of exposure under the given exposure conditions. Also the molybdenum-alloyed ferritic steel 1.4521 showed good corrosion resistance comparable to the classical austenitic materials 1.4301 and 1.4404.
