    Stress corrosion cracking (SCC) refers to the cracking or fracture failure of metal materials under the combined action of stress and specific media. Commonly used metal materials in engineering, such as stainless steel, carbon steel, high-strength steel, etc., may occur SCC in a specific medium, and according to the harsh degree of corrosion conditions, the material can be broken in a few minutes or years. During the corrosion process, microcracks appear in the material first, and then expand into macroscopic cracks. Once microcracks are formed, their growth rate is much faster than other types of local corrosion, so SCC is the most destructive and harmful corrosion of all types of corrosion, and it accounts for a large proportion of many equipment accidents. T,C&A Lab provides stress corrosion testing services to evaluate whether the material is susceptible to stress corrosion cracking in an environmental medium, so as to provide a reference for the selection of suitable service materials.
