Ko te GER-N27L me te GER-N27 e whakaputahia ana e matou ko nga hiko hiko iti-waikawa konutai-whakakikoruatia i te wera iti me te ihirangi Ni o 2.5%, he maha nga wa e whakamahia ana mo te whakapiri ASME SA-203 GrA / B me te 09MnNiDR maitai. Ko nga tauira o GER-N27L me GER-N27 e whakatinana ana i te GB/T5117-2012 i tenei wa ko E5015-N5 P/E5015-G P me E5515-N5 P, e rite ana ki nga tohu o te "Welding Materials Product Handbook" i whakaputaina e Miihini. Perehi Ahumahi. Mo te W707 me te W707Ni, ko nga ahuatanga o te tinana me te matū o te konganuku kua whakatakotoria o nga hiko e rua ka whakatauritea penei.

Ka kitea mai i te ripanga i runga ake nei ko te hanganga matū C me Si o te whakarewa o te GER-N27 (W707Ni) kua tohua he paku teitei ake i era o GER-N27L (W707). No reira, i runga i te kaha, no te GER-N27L (W707) te hiko o te karaehe 490MPa me te iti o te kaha tensile. Ko te GER-N27 (W707Ni) he taumata, a, ko te paanga o te mahi o te GER-N27L (W707) e rite ana he paku pai ake i te GER-N27 (W707Ni), engari i roto i nga whakamahinga mahi, GER-N27L (W707) me GER-N27 ( W707Ni) pānga Ka whakaaetia te whakamatautau kia rite ki te tohu o -70°C, -75°C ranei.

Ko te GER-N27L me te GER-N27 he pai te pai o te weldability-katoa i te wa e whakapiri ana i te ASME SA-203 GrA/B ranei 09MnNiDR maitai (penei i te ahua o runga ake nei mo te hanganga o te tui poutū o nga hiko e rua), a ko te tikanga. E taunaki ana kia kaua e neke ake i te 35kJ /cm te kaha o te raina whakapiri, kia whiwhi ai i te hanganga tino pai e te ferrite acicular. I te wa e whakamahia ana te GER-N27L (W707) ki nga taputapu e hiahia ana ki te tinei me te whakamaarama i te wera wera + te whakamaarama i te wera o te wera, ko te tikanga kia pai ake te kaha o te paanga o te pāmahana iti, engari ka ngaro te kaha, ka iti ake te kaha o te kaha. 500MPa; GER-N27L (W707) I tua atu i nga pourewa, ka whakamahia ano hoki i roto i te 09MnNiDR rino ethylene spherical tanks, i te wa e whakamahia ana a GER-N27 (W707Ni) i roto i nga ipu iti-mahana e hiahia ana ki te maimoatanga wera wera. Ko nga mea e whai ake nei ka whakaatu i nga tauira o te tono me nga mahi e pa ana ki a GER-N27L me GER-N27.
