In　order　to　make　equipments　and　vessels　run　safety　in　the　environments　which　contain　H2S,　according　to　NACE　TM0284-2003,　hydrogen　induced　cracking　(HIC)-resistance　properties　of　four　types　of　steel　with　different　processing　technologies　are　tested　in　this　paper,　and　crack　length　rate　(CLR),　crack　thickness　rate　(CTR)　and　crack　sensitive　rate　(CSR)　are　calculated.　Combined　with　theirs　mechanical　properties,　the　difference　of　those　four　types　of　steel　is　analyzed　quantificationally,　and　the　allround　properties　are　evaluated.　Base　on　the　analysis,　microstructures　are　observed　by　metallographic　microscope　and　directions　of　cracks　are　observed　by　scanning　electron　microscope　to　analyze　the　difference　of　HIC-resistance　properties　of　the　steels　with　different　processing　technologies,　and　get　the　conclusion　that　zonal　structure　along　with　the　rolling　direction,　heterogeneity　of　material　and　nonmetal　inclusion　are　the　mainly　reason,　of　hydrogen　induced　cracking.
