Equivalent Accelerated Corrosion Test of 30CrMnSiA Alloy Steel

Based on the environmental spectrum of a certain area, 30CrMnSiA was used to prepare specimens of bolted lap joints. Part of joints were tested in field accelerated environment corrosion testing was carried out in laboratory . Weight loss and fatigue life were used to evaluate the corrosion degree. The results showed that the weight loss and fatigue life for accelerated corrosion and natural aging corrosion were consistent at the confidence level of 95% in matched time.
