EFFECT OF SOME ELECTROLYTES ON THE STRESS CORROSION CRACKING OF AISI 4340 STEEL

In strongly buffered solutions, there was a strong pH dependence; the time to failure in 10% NaCl increased about 100 fold between pH 4 to 5 and pH 7. Susceptibility to cracking increased moderately with the concentration of KNO3 solutions, but decreased with rising concentration on NaCl solutions. The cracking rate increased by 50% per 10 C for NaCl solutions. Results are shown for the remainder of 16 electrolytes. Correlation was poor with unbuffered solutions.
