The corrosion of stainless steel (304L) and low-alloy steel (T22) in the 2 MW Chalmers gasifier was investigated. To understand corrosion in the real gasifier, simplified laboratory experiments were performed, focussing on the effect of H. 2. and H. 2. O on different high temperature alloys. While 304L What causes intergranular corrosion in stainless steel?What causes intergranular corrosion in stainless steel?Intergranular Corrosion - all austentic stainless steels contain a small amount of carbon. At extremely high temperature, such as welding, the carbon forces local chrome to form chromium carbide around it, thus starving adjacent areas of the chrome it needs for its own corrosion p rotection.18-8 Stainless steel, 304, 316 Stainless Steel Corrosion What causes the pitting of stainless steel steel?What causes the pitting of stainless steel steel?One common cause of pitting corrosion is exposure to aqueous environments that contain chloride. Examples are coastal atmospheres, road salt combined with rain water, and even tap water containing high levels of chloride. During the fabrication of stainless steel components or structures it is possible to degrade the corrosion resistance.Why is Stainless Steel Corrosion Resistant? - Industrial PDF Unexpected corrosion of stainless steel in low

Which is more susceptible to corrosion 317l or 304L?Which is more susceptible to corrosion 317l or 304L?In general, austenitic stainless steels are subject to chloride stress corrosion cracking in halide service. Although 317L is somewhat more resistant to stress corrosion cracking than 304/304L stainless steels, because of its higher molybdenum content, it is still susceptible.Specification Sheet Alloy 317L - Sandmeyer Steel(PDF) A CASE STUDY ON CORROSION OF STAINLESS STEEL

Iron oxidising bacteria can oxidize ferrous iron to ferric iron, which then reacts with the chloride ions A02-16 producing ferric chloride [6]. Ferric chloride is extremely aggressive causing pitting corrosion on stainless steel.

This is not so in water there, corrosion as function of temperature shows a marked maximum around 250" C for AISI 410 steel. For AISI 304 steel the maximum, which was not actually observed, must lie at a lower temperature.Cited by 2Publish Year 2009Author Lisbeth Rischel Hilbert, Leena Carpén, Per Møller, Frank Fontenay, Troels MathiesenOriginal language EnglishPeople also askWhy does a low grade stainless steel resist corrosion?Why does a low grade stainless steel resist corrosion?Low alloy grades can resist corrosion in normal conditions. Higher alloys resist corrosion by most acids, alkaline solutions and chloride environments. The corrosion resistance of stainless steel is due to their chromium content.
