Effect of Temperature on Stress Corrosion Cracking of 300M Steel

CODEN: JTEVAB

Abstract

The effect of temperature on stress corrosion cracking of high-carbon 300M high-strength steel in deionized water was investigated. Tests were conducted with wedge-opening-load specimens at 0, 23, and 90°C. Stress corrosion crack growth rates above the stress corrosion cracking threshold KIscc were found to increase with increasing temperature and to be essentially constant at each temperature. The crack growth rates appeared to be described by an Arrhenius-type rate expression. The apparent stress corrosion cracking threshold KIscc at 23°C was approximately 12.1 MPa · m½ (11 ksi·in.½) and at 90°C, 16.5 MPa·m½ (15 ksi·in.½). At 0°C, KIscc appeared to be lower than at 23°C.
