AbstractPurpose -To make clear that C-steel can differ very much in corrosion resistance under practical conditions only because of differences in chemical composition of the steels. Design/methodology/approach -In the electricity generating industry, "mild" (i.e. "plain carbon") and low-alloyed steels are used in huge quantities, for instance, in boilers, steam generators, heat recovery boilers and waste incineration boilers. The resistance to strain induced corrosion cracking (SICC) was determined by measuring the "repassivation" behaviour of the steels at freshly ground surfaces with an electrochemical technique. The corrosion current measured with time was used to calculate the cracking rates of a compact tension specimen. Findings -A correlation was found between chemical composition, corrosion resistance to SICC and experiences under practical conditions. The results of early-published papers on boiler corrosion (testing in FeCl 2 solutions), erosion corrosion (testing in wet steam at 20 bar), nitrate stress corrosion cracking (testing in NH 4 NO 3 solutions) and SICC together with those originating from in-service failures, were compiled into a reference database. This paper is a compilation of this work too. Originality/value -The database and formulas presented make clear there is often a direct correlation between chemical composition of ordinary C-steel and mentioned types of corrosion failures. The paper is of importance to designers, failure analysts and researchers.

Corrosion degradation of pipeline carbon steels subjected to geothermal plant conditions

“…The beneficial influence of Cu, Cr and Mo additions to carbon steel to improve its corrosion resistance in geothermal service operation conditions at the wet steam lines has been reported and indicates that these are the most beneficial alloy elements (Huijbregts and Leferink, 2006).…”

“…Low-alloyed steels form major materials in the manufacture of live and reheat steam pipelines (Golanski et al , 2016), steam generators, economizer assemblies, super heater, re-heaters (Reddy et al , 2014), pressure vessels and piping (Perez et al , 2011) and boilers (Huijbregt and Leferink, 2006) which find applications in petrochemical, process, marine and power industries to mention but a few. De-scaling of facilities of this sort is usually carried out to improve service performances.…”
