ASTM A262 Intergranular Corrosion Testing And Analysis
The oxalic acid test is commonly used before the Strauss test to determine if a sample is susceptible; samples that pass method A will generally show low corrosion rates in the Strauss test. The samples are boiled in a Cu-Copper Sulfate mixture for 15 hours and then bent 180° over an equal diameter bend. ... Fetch Doc

Passivation Of Stainless Steel
Sulfate test. Passivated parts are immersed in a copper sulfate solution for 6 minutes, rinsed, and visually examined. Any copper (pink) color indicates the presence of free iron, and the test is considered unacceptable. Other validation tests include a 2 hour Salt Spray or 24 hour high-humidity test. ...
