This post was last edited by FORREST_GUMP on 2015-12-1 19:09. Q345R(HIC) and Q345R(R-HIC) are both corrosion-resistant steel plates designed for use in environments with hydrogen sulfide, but they undergo different testing procedures. Q345R(R-HIC) requires an additional SSCC test compared to Q345R(HIC). As for whether to use Solution A or Solution B for the testing, this decision depends on the customer’s requirements.

It is recommended to provide basic knowledge on HIC and SSC: lol

HIC hydrogen corrosion, namely hydrogen blistering and hydrogen embrittlement. SSC stands for hydrogen sulfide stress corrosion.
