boiling nitric acid test for corrosion;Huey test
Molecular formula :

nature : off - also known as a Pap smear test. A widely used test of stainless steel, intergranular corrosion sensitivity of the standard method. Samples will be brought back on stream condenser filled with a 65% HNO3 containers, boiling in a state soaking certain cycle, and then through the weightlessness of materials to evaluate the intergranular corrosion tendencies. The method can be selective corrosion poor district of chromium carbide, σ is the segregation of impurity elements. Its biggest advantage is the most simple method to test the weightlessness intergranular corrosion, and is commonly used to control product quality stainless steel materials testing methods.
