Abstract
The susceptibility to environmental embrittlement (EE) of automobile spring steels was investigated using six different steels. Slow strain rate tensile test and thermal desorption spectroscopic analysis were applied to specimens subjected to wet–dry cyclic corrosion tests in a NaCl solution. Experimental results revealed that the reduction in ductility after the corrosion tests was pronounced with increasing strength level. This degradation was closely associated with the resistance to pitting corrosion. Consequently, the hydrogen absorbed in steel and the corrosion pit as a geometric damage were responsible for the EE of spring steels. The hydrogen in rust layer had no significant influence on the EE.
