ASTM A262 Practice C - Nitric Acid (Huey Test)

EUROLAB laboratory provides testing and compliance services within the scope of ASTM A262 standard. Samples are boiled in a 65 percent nitric acid solution for five periods of 48 hours each. The corrosion rate at each boiling period is calculated from the reduction in weight of the samples. When interpreted correctly, the results can reveal whether the steel has been properly heat treated.

ASTM A262 Practice C - Nitric Acid (Huey Test)

The Huey test medium is strongly oxidizing and is only used to check if the material has been properly heat treated. This test is suitable for detecting chromium deficient regions in the material as well as intermetallic precipitations such as the sigma phase. The Huey test is also used for materials that come into contact with strong oxidizing agents such as nitric acid. This procedure can also be used to check the effectiveness of stabilizing elements and reductions in carbon content in reducing susceptibility to intergranular attack in chromium-nickel stainless steel.

The presence or absence of intergranular attack in these tests is not a measure of the material's performance in other corrosive environments. These tests do not provide a basis for estimating resistance to non-intergranular forms of corrosion such as general corrosion, pitting, or stress-corrosion cracking.
