Abstract
For the purpose of finding the most suitable laboratory corrosion test to estimate the corrosion resistance of 18 Cr stainless steel (SUS 24) strips under atmospheric circumstances, field test and laboratory tests, i. e. salt spray test, humidity test, dew-cycle corrosion test, thermographic corrosion test, and boiling nitric acid test (6hrs and 48hrs) were applied to 12 kinds of 18 Cr stainless steel strips. But the results of all the laboratory tests didn't coincide with the one of the field test. There were, however, a few kinds of strips that showed comparatively good (No. 2) or poor (No. 1) performance through all the tests.
