Paper Title:
The Corrosion Behaviors of Heat-Treated SAE 8620 Steels
  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.
