The failure of the protective oxide scales of AISI 304 and AISI 316 stainless steels has been studied and compared at 1,000°C in synthetic air. First, the isothermal thermogravimetric curves of both stainless steels were plotted to determine the time needed to reach the breakdown point. The different resistance of each stainless steel was interpreted on the basis of the nature of the crystalline phases formed, the morphology, and the surface structure as well as the cross-section structure of the oxidation products. The weight gain of AISI 304 stainless steel was about 8 times greater than that of AISI 316 stainless steel, and AISI 316 stainless steel reached the breakdown point about 40 times more slowly than AISI 304 stainless steel. In both stainless steels, reaching the breakdown point meant the loss of the protective oxide scale of Cr2O3, but whereas in AISI 304 stainless steel the Cr2O3scale totally disappeared and exclusively Fe2O3was formed, in AISI 316 stainless steel some Cr2O3persisted and Fe3O4was mainly formed, which means that AISI 316 stainless steel is more resistant to oxidation after the breakdown.

Pipe Manufacturing

This article deals with the performance of heat pipes, depending on the operating temperature and positions (operation angle). There is described the essential function of the heat pipe manufacturing process. Measurements were carried at an operating temperature of 40 °C to 90 °C. Stainless heat pipes were made of three kinds of materials AISI 304, AISI 310, AISI 316 and filled with a distilled water, up to 20% of the heat pipe inner volume. For each material was selected heat pipe with the best results. The heat pipes were measured at various angles of vertical inclination (0 ° - 90 °), at the working temperature 90 ° C. The performance was measured on the experimental device. Presented results show the progress of individual measurements and the effect of operating parameters on the performance of heat pipes.

Abstract The corrosion behavior of AISI 304 and 316 stainless steels (SSs) in hot concentrated caustic soda solutions was investigated under heat-transfer conditions. The corrosion potential of the specimens was located in the active region; thus, the alloys were attacked in the form of general corrosion, depending on the heat-transfer conditions. AISI 316 was more susceptible than AISI 304. Such corrosion behavior is attributed to the failure of the passive film on the heated surface, caused by concentration of caustic solution next to the metal surface and erosion by gas bubbles. A molybdenum-free alloy, AISI 305J1, was tested under the same conditions as AISI 316 to clarify the detrimental effect of Mo on austenitic SS corrosion in hot concentrated NaOH. Intergranular corrosion was occasionally found when the potential was located in the passive region, depending on test conditions and heat treatment of the specimens.

Abstract Potentiostatic, potentiodynamic, and immersion tests were conducted on a range of alloys used in paper-machine service. It was found that thiosulfate contamination of white water can cause pitting in AISI 304 and CA-15 stainless steels (SS), and, by comparison, salts such as NaCl, Na2SO, and Al2(SO4)3 are much less corrosive. For sensitized AISI 304, thiosulfate levels in the range of 3 to 75 ppm cause pitting, 5 to 20 ppm S2O3= being particularly aggressive. Thiosulfate pitting occurred in the absence of chlorides when sulfate was present at SO4=:S2O3= molar ratios from 1.6 to 58. Compared to AISI 304, significantly greater resistance to thiosulfate pitting was found in AISI 316 and 317 L, Ferralium 255, and cast duplex SS, KCR-A171 and Alloy 75.
