Keywords: | Corrosion behavior | Heat treatment | Microstructure | SAE 8620 steel | Stress corrosion | Issue Date: | 21-Jul-2008 | Journal Volume: | 575-578 PART 2 | Start page/Pages: | 1190 | Source: | Materials Science Forum | Abstract: | The corrosion behaviors, including the immersion corrosion, electro-chemical corrosion, stress-corrosion fracture, of heat-treated SAE 8620 steels have been investigated. Experimental results show that the 400°C tempered specimen is only susceptible to local attack of pitting corrosion and can exhibit an excellent corrosion resistance during the static immersion and electro-chemical tests in a 3.5% NaCl solution. The tensile strength and elongation of the normalized and 300-500°C tempered specimens will be reduced when tested in NaCl solutions, especially at a higher testing temperature. The normalized specimen can inhibit effectively the crack-growth under constant loading and the 300-500°C tempered specimens have a sequence of crack-growth rate as 300°C > 400°C > 500°C. |
