Resistance to Stress Corrosion Cracking

A common solution for assessing the resistance to chloride-induced stress corrosion cracking of a material is boiling 45 wt.% magnesium chloride. This table indicates the times required to induce cracking in U-bend samples. The tests were stopped after six weeks (1,008 hours).
