Different Types of Corrosion Stress Corrosion Cracking

What causes stress corrosion cracking? Stress corrosion cracking results from the conjoint action of three components (1) a susceptible material; (2) a specific chemical species (environment) and (3) tensile stress.For example,copper and its alloys are susceptible to ammonia compounds,mild steels are susceptible to alkalis and stainless steels are susceptible to chlorides.Corrosion,coating,wire rope anchor testing DNV GL Quality control and qualification of performance.Stress corrosion testing in H2S containing environments.Qualify materials and components for H2S exposure.Qualification of materials,coating and inhibitors.Corrosion and corrosion protection quality control.TenTune.Measurement of mooring line tension.Cost-efficient solutions for offshore Corrosion and Stress Corrosion Testing of Aerospace Standard /reference data on environmental properties,including corrosion and stress corrosion,are mandatory for the qualification and certification of materials for aerospace vehicles,and also for the design of actual structures and components.Recommendations for further testing and evaluation are given at appropriate points in the text.
