Are anti-H2S steel and anti-HIC steel the same type of steel?

Reply #22019-06-03

It’s not the same thing; there is no dedicated anti-H2S steel. The materials used for containers as specified in GB713 can require anti-HIC testing to be carried out as per the contract. Manufactured in accordance with GB713 standards; the steel plate grade is followed by (HIC) or (R-HIC). For example, Q345R(HIC) refers to Q345R container steel that has undergone testing for hydrogen-induced cracking resistance, while Q345R(R-HIC) is Q345R(HIC) with an additional test for sscc, namely sulfide stress corrosion testing.
