I-GER-N27L ne-GER-N27 esiyikhiqizayo womabili ama-electrode ensimbi anezinga lokushisa eliphansi le-hydrogen sodium-coated ane-Ni content engu-2.5%, avame ukusetshenziselwa ukushisela izinsimbi ze-ASME SA-203 GrA/B kanye ne-09MnNiDR.Amamodeli e-GER-N27L kanye ne-GER-N27 asebenzisa i-GB/T5117-2012 njengamanje yi-E5015-N5 P/E5015-G P kanye ne-E5515-N5 P ngokulandelana, ahambisana namabanga "I-Welding Materials Product Handbook" eshicilelwe yiMishini. Imboni Press.Ku-W707 kanye ne-W707Ni, izakhiwo ezingokomzimba nezamakhemikhali zensimbi efakiwe zama-electrode amabili ziqhathaniswa kanje.

Kungabonakala etafuleni elingenhla ukuthi ukwakheka kwamakhemikhali C kanye no-Si wensimbi efakwe i-GER-N27 (W707Ni) kuphakeme kancane kunaleyo ye-GER-N27L (W707).Ngakho-ke, ngokwamandla, i-GER-N27L (W707) ingeye-electrode yebanga le-490MPa enamandla aphansi.I-GER-N27 (W707Ni) izinga, futhi ukusebenza komthelela kwe-GER-N27L (W707) ehambisanayo kungcono kancane kune-GER-N27 (W707Ni), kodwa ekusebenzeni okungokoqobo, i-GER-N27L (W707) kanye ne-GER-N27 ( W707Ni) umthelela Ukuhlolwa ngokuvamile kwamukelwe ngokwenkomba engu -70°C noma -75°C.

I-GER-N27L ne-GER-N27 zinokushisela okuhle kakhulu kwesikhundla sonke lapho zishisela i-ASME SA-203 GrA/B noma insimbi engu-09MnNiDR (njengoba kukhonjisiwe esithombeni esingenhla sokwakhiwa komthungo wokushisela oqondile wama-electrode amabili), futhi ngokuvamile kunconywa ukuthi amandla omugqa wokushisela akufanele adlule ku-35kJ / cm, ukuze uthole isakhiwo esihle kakhulu esibuswa yi-acicular ferrite.Uma i-GER-N27L (W707) isetshenziswa ezintweni ezidinga ukucishwa kanye nokwelashwa kokushisa okubabayo + ukwelashwa kokushisa kwe-annealing, ngokuvamile iwukuthola ukuqina komthelela wezinga lokushisa eliphansi elingcono, kodwa izolahlekelwa amandla athile, futhi amandla aqinile ngokuvamile aphansi 500MPa;I-GER-N27L (W707) Ngaphezu kwemibhoshongo, iphinde isetshenziswe ku-09MnNiDR steel ethylene spherical tanks, kuyilapho i-GER-N27 (W707Ni) ivame ukusetshenziswa ezitsheni ezinokushisa okuphansi ezidinga kuphela ukwelashwa kokushisa kwe-annealing.Okulandelayo kuzonikeza izibonelo zohlelo lokusebenza nokusebenza okuhlobene kwe-GER-N27L ne-GER-N27.
