Abstract
Crack propagation testing of type 316L stainless steel, with different hardness levels, in high temperature water has been performed, and the relationship between SCC growth rate (da/dt) and hardness (Hv) discussed. Intergranular crack propagation was observed in both solution treated material and cold worked materials. Highly cold worked material showed a higher crack propagation rate. Using the strain distribution near the crack tip and the SCC susceptible plastic zone size, where the hardness was higher than the critical Vickers hardness for SCC susceptibility (Hvc), the crack propagation rate for low carbon stainless steel, under the fixed environment, could be described as da/dt=A·K2/(Hvc-Hv0)2, where K is the stress intensity factor, Hvc is the critical hardness for SCC (defined as a Vickers hardness of 300), and HV0 is the Vickers hardness of the base material.
