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.Corrosion behavior | Heat treatment | Microstructure | SAE 8620 steel | Stress corrosionconference paper2-s2.0-47249116901https://api.elsevier.com/content/abstract/scopus_id/47249116901
