Can stainless steel used to seal lead in a tumbler cup be susceptible to corrosion?

Crevice corrosion

Best insight from top research papers

Stainless steel used to seal lead in a tumbler cup can indeed be susceptible to corrosion, especially in specific conditions. Research has shown that the interaction between stainless steel and lead vanado-iodoapatite (I-APT) in a chloride solution can lead to crevice corrosion, creating an aggressive environment enriched in Cl− anions . This corrosion process can accelerate the release of iodine from the I-APT matrix and result in the formation of Cl-bearing precipitates on the surfaces of both stainless steel and I-APT . While stainless steel is generally corrosion-resistant due to its passive film, in certain scenarios like the one described, it can be prone to corrosion when in contact with specific materials and environments.

Erosion corrosion of steels in liquid lead ?4 answersErosion corrosion of steels in liquid lead has been studied in several papers. The corrosion behavior of ferritic (Fe-11Cr) and austenitic (Fe-18Cr) steels was investigated in static liquid lead containing 5 × 10–7 wt.% oxygen at 550°C. It was found that corrosion damage occurs along grain boundaries, accompanied by etching and penetration of liquid lead into the matrix. The applied loads were found to accelerate the corrosion processes, with the austenitic steel showing better corrosion resistance than the ferritic steel. T91 samples exposed to static liquid lead-bismuth eutectic (LBE) at 700°C showed corrosion damage characterized by LBE intrusion beneath LBE-wetted surfaces. Local depletion of Cr was observed, suggesting local Cr dissolution as the main corrosion mechanism. The CORELLA facility allows corrosion erosion tests in molten lead alloys, and a numerical study found highly turbulent flow and a higher effect of flow on corrosion erosion compared to simple pipe flow. The technology of heavy liquid metal (HLM) cooled systems requires studying materials corrosion, and different surface treatments and coatings were evaluated to improve corrosion resistance.

What are the factors that contribute to corrosion in lead-cooled reactors, specifically in relation to 316L stainless steel?4 answersCorrosion in lead-cooled reactors, specifically in relation to 316L stainless steel, is influenced by several factors. The presence of oxygen in the coolant significantly affects the corrosion behavior of 316L stainless steel, with higher oxygen levels leading to the formation of multi-oxide layers on the alloy surface. The corrosion depth and the type of oxide product formed also depend on the oxygen content, with higher oxygen levels resulting in dissolution corrosion and the formation of a dense Fe-Cr oxide layer. Additionally, the flow velocity of the lead coolant plays a role in the corrosion process, with higher velocities leading to erosion-corrosion and affecting the thickness of the affected zone. The dissolution and mass transfer of alloying elements, such as nickel, from the structural materials to the coolant also contribute to corrosion in lead-cooled reactors.

Does stainless steel corrode with carbonates?5 answersStainless steel can corrode when exposed to carbonates. The corrosion rate and mechanism depend on various factors such as the specific carbonate composition, gas environment, and exposure conditions. In some cases, the presence of carbonates can accelerate the corrosion of stainless steel, leading to the formation of porous scales. However, the corrosion resistance of stainless steel can be improved by using certain pretreatment methods or coatings. For example, in-situ corrosion pretreatment with N2-20%O2 gas can suppress the dissolution of corrosion products and enhance corrosion resistance. Additionally, the use of stainless steel reinforcement in chloride-contaminated concrete has been studied, and certain stainless steel alloys have shown good corrosion resistance even in carbonated concrete and harsh exposure conditions. Overall, the corrosion behavior of stainless steel in carbonates is influenced by various factors and can be mitigated through appropriate pretreatment or material selection.

What are the advantages and disadvantages of using stainless steel in the food industry?5 answersStainless steel has several advantages in the food industry. It is highly corrosion resistant, making it durable and suitable for use in harsh cleaning chemical conditions. Stainless steel also has superior mechanical properties, ensuring the quality and purity of produced foodstuffs and drugs. Additionally, stainless steel utensils are resistant to rust and chemicals in foods and drinks, making them safe and hygienic for use.

Can corrosion cause solderability issue?5 answersCorrosion can indeed cause solderability issues. The abstracts provide evidence that oxidation of copper due to corrosion can lead to decreased solderability. In one study, it was found that organic solderability preservative coatings (OSP) decomposed under heat, causing oxidation of the copper and affecting solderability. Another study showed that inhibitors applied to copper effectively reduced oxidation and improved solderability. Additionally, the presence of certain elements in copper alloys, such as zinc, can also impact solderability. Therefore, it is clear that corrosion can have a negative impact on solderability, and measures such as using corrosion protection coatings or selecting appropriate alloy compositions can help mitigate these issues.

How does the corrosion threshold of 316L stainless steel in concrete vary with different environmental conditions?1 answersThe corrosion threshold of 316L stainless steel in concrete varies with different environmental conditions. The presence of chloride (Cl–) and thiosulfate (S2O32–) accelerates general corrosion, but the pitting resistance of additively manufactured (AM) 316L stainless steel is 4-6 times higher than that of the wrought sample, depending on the S2O32– concentration. The corrosion resistance of 316L stainless steel components manufactured with selective laser melting (SLM) technology is influenced by surface orientation, with the highest corrosion rate observed in the presence of H2SO4 solution. The corrosion behavior of 316L stainless steel in aqueous NaOH at elevated temperatures is characterized by parabolic weight loss and the formation of iron-oxy-hydroxide and nickel-oxide. The electrochemical performance of 316L stainless steel rebars in concrete is improved by the presence of fly ash up to 20 wt.%, but this trend is reversed at 25 wt.%.
