To　evaluate　the　hydrogen　resistant　properties　of　the　15CrMoR(H)　with　new　smelting　process,　according　to　NACE　and　National　Standards,　three　tests　including　NACE　standard　tensile　test,　NACE　standard　bent-beam　test　and　hydrogen　induced　cracking　test　are　executed　in　saturated　hydrogen　sulfide(H2S)　environment.　Stress-life　mathematical　model　of　this　material　is　given　by　analyzing　and　fitting　the　results　of　tensile　test.　Test　results　show　that　the　threshold　sigma　th　of　tensile　test　is　0.7R(eL)(252MPa);　the　threshold　nominal　stress　Sc　of　bent-beam　is　higher　than　4.5　R-eL　(1620MPa);　for　HIC　test,　the　crack　length　rate　CLR　is　4.40%,　the　crack　thickness　rate　CTR　is　0.87%　and　the　crack　sensitive　rate　CSR　is　0.04%.　Compare　with　EFC　standard,　the　safety　margin　of　HIC　test　is　3.4,　3.4　and　37.5　times　respectively.　All　the　experimental　results　show　that　the　new　15CrMoR(H)　material　has　excellent　H2S　environmental　cracking　resistance　properties.
