In order to study the distribution behavior of hydrogen in metals under the condition of H2S corrosion. a layer-stripping micro-hardness test was designed to analyze the hydrogen distribution along the depth of hydrogen-charged 45 high-quality structural carbon steel at three different hydrogen sulfide concentrations and four corrosion periods in this study. The results show that ther... https://hollandscountryclothinges.shop/product-category/cleaning-patches/
