| 摘要 |
Disclosed is a corrosion testing device for metal specimens which can expose a structure etched by heating specimens put in a hydrochloric acid aqueous solution so as to test the internal solidification structure of steel. The present invention comprises: a corrosion testing part having corrosion tanks for storing an acidic solution; and a specimen transfer part for inputting a specimen rack, on which multiple specimens are mounted, into the corrosion testing part to be immerged in the corrosion tanks. The present invention can develop high quality products by testing the corrosion resistance of the steel specimens, and can prevent air pollution by discharging fume generated during the test after the fume is neutralized below a reference value. |
