What are the risks of stress corrosion cracking in stainless steel figurative sculptures?
Stress corrosion cracking (SCC) is a significant risk for stainless steel figurative sculptures, especially those exposed to harsh environments. This type of corrosion occurs when tensile stress and a corrosive environment combine, leading to cracks that can compromise the structural integrity of the artwork. Chloride-rich environments, such as coastal areas or places with de-icing salts, accelerate SCC. Additionally, poor fabrication techniques or residual stresses from welding can increase susceptibility. To mitigate these risks, artists and conservators should use high-quality stainless steel grades (e.g., 316L), apply protective coatings, and conduct regular inspections. Proper maintenance ensures the longevity and aesthetic appeal of metal sculptures.
