... the five fungal isolates, Non – rusted Isolate (NR) – 1 and Rusted Isolate (R) – 3 showed minimum corrosion reaction on mild steel plates, based on the results of weight loss and dissolved iron content. The results revealed that the two isolates showed minimum rate of corrosion on mild steel plates due...

... Abstract Corrosion tests were carried out to determine the effect of iron content on localised corrosion and stress corrosion cracking (SCC) resistance of Ni-Cr-Mo alloy weld overlays (i.e. Alloy 625) in H2S environments. In addition, the influence of iron content on the fatigue crack growth...

... Abstract Corrosion tests were carried out to determine the effect of iron content on localised corrosion resistance of Ni-Cr-Mo alloy weld overlays (e.g. Alloy 625) in chloride ion-containing environments. A range of iron contents (i.e. 5 – 50%) were examined using coupons extracted from weld...

... with the purpose of achieving 6 goals. 1. Reduce the corrosion rate from an average of 47 mpy to <5 mpy. 2. Reduce the scaling rate. 3. Reduce the dissolved iron content of the water. 4. To conclude whether the dissolved iron is coming from corrosion of tubulars, from the formation, or from a combination...

... integrity. It is also shown from these field results that iron contents exceeding 100 to 200 mg/l at the outlet of sweet gas pipelines are not necessarily alarming. For quite long pipelines these counts correspond to fully acceptable residual corrosion rates. In case of such high iron levels, the present...

... of 190 and 925 hours respectively. The susceptibility was not directly proportional to the iron content since HR-120 (UNS N08120) had the lower iron level, but experienced metal dusting sooner. The final metal wastage rate of HR-120 alloy (UNS N08120) was also almost an order of magnitude higher than...
