Q345R(R-HIC)はHIC+sscc試験(硫化物応力誘起試験)を行い、Q345R(HIC)はHIC試験のみを行う。Q345R(R-HIC)の価格はQ345R(HIC)よりも少し高い。このフォーラムにも類似のスレッドがある。http://bbs.hcbbs.com/thread-631054-1-1.html

GB713-2014の付録Aを参照:HICは「水素誘起き裂け」(Hydrogen Induced Cracking)を意味し、Rは耐性(Resist)を意味する。 R-HICとHICの違いは、前者に1つ文字が余分に書かれているだけです。Q345R(R-HIC)とQ345(HIC)は同じ材料を指し、前者の表現の方がより明確です。HICは避けるべきものです。
