Iyo GER-N27L neGER-N27 yatinogadzira ese ari maviri akaderera-hydrogen sodium-coated yakaderera-temperature simbi maelectrodes ane Ni content ye2.5%, ayo anowanzo shandiswa simbi dzeASME SA-203 GrA/B uye 09MnNiDR. Mamodheru eGER-N27L neGER-N27 ari kuita GB/T5117-2012 ari E5015-N5 P/E5015-G P uye E5515-N5 P zvichiteerana, anowirirana nemagiredhi e "Welding Materials Product Handbook" yakaburitswa neMichina. Vadivelu Comedy Industry Press. Kune W707 uye W707Ni, iyo yemuviri uye yemakemikari zvimiro zvesimbi yakaiswa yeaviri maelectrode inofananidzwa sezvinotevera.

Zvinogona kuonekwa kubva patafura iri pamusoro apa kuti kemikari yakagadzirwa C uye Si yesimbi yakaiswa yeGER-N27 (W707Ni) yakakwirira zvishoma kudarika yeGER-N27L (W707). Naizvozvo, maererano nesimba, GER-N27L (W707) ndeye 490MPa giredhi electrode ine yakaderera tensile simba. GER-N27 (W707Ni) idanho, uye kushanda kweiyo inoenderana GER-N27L (W707) iri nani zvishoma pane GER-N27 (W707Ni), asi mumashandisirwo anoshanda, GER-N27L (W707) uye GER-N27 ( W707Ni) kukanganisa Muedzo unowanzo gamuchirwa maererano nendekisi ye -70°C kana -75°C.

GER-N27L uye GER-N27 vane yakanakisa-chinzvimbo cheldability kana welding ASME SA-203 GrA/B kana 09MnNiDR simbi (sezviri kuratidzwa mumufananidzo uri pamusoro pekugadzirwa kweiyo vertical welding seam yemaelectrode maviri), uye kazhinji kazhinji. yakakurudzira kuti welding line simba haifaniri kudarika 35kJ / cm, kuitira kuti uwane chimiro chakanakisisa chinotungamirirwa ne acicular ferrite. Kana GER-N27L (W707) ichiiswa kumidziyo inoda kudzimwa uye kupisa kupisa kurapwa + annealing kupisa kurapwa, kazhinji kuwana zvirinani kuderera-tembiricha kukanganisa kuomarara, asi kunorasikirwa nerimwe simba, uye simba rekusimba rinowanzo kudzika kupfuura. 500MPa; GER-N27L (W707) Pamusoro peshongwe, inoshandiswawo mu09MnNiDR simbi ethylene spherical matangi, nepo GER-N27 (W707Ni) inowanzo shandiswa mumidziyo yakadzika-tembiricha inongoda annealing kupisa kurapwa. Izvi zvinotevera zvinopa mienzaniso yekushandiswa uye kuita kwakabatana kweGER-N27L uye GER-N27.
