Civil airplane suffers from different atmospheric environments and local environments.
The atmospheric environments have been classified as eight typical lab environments by engineering experience[5], so that the basic corrosive fatigue data such as crack growth rate constant etc. under single environment are obtained in lab.
Steel 30CrMnSiNi2A is low alloy and high strength metal material which is widely used in engineering.
To meet the requirement of engineering, a general method is to modify the Paris's equation (Eq.(1) for example) which is fitted by experimental data under the environment of lab air and room temperature.
