O le GER-N27L ma le GER-N27 o loʻo matou gaosia e lua e lua eletise eletise maualalo-hydrogen sodium-coated low-temperature electrodes ma se mea Nini o le 2.5%, lea e masani ona faʻaaogaina mo uʻamea ASME SA-203 GrA / B ma 09MnNiDR uamea. O faʻataʻitaʻiga o GER-N27L ma GER-N27 o loʻo faʻaaogaina nei GB / T5117-2012 o le E5015-N5 P / E5015-G P ma le E5515-N5 P taʻitasi, e fetaui ma togi o le "Welding Materials Product Handbook" lomia e Machinery Alamanuia Lomitusi. Mo W707 ma W707Ni, o mea faʻapitoa ma vailaʻau o le uʻamea teuina o le lua eletise e faʻatusatusa i lalo.

E mafai ona iloa mai le laulau o loʻo i luga o le vailaʻau vailaʻau C ma le Si o le uamea teuina o GER-N27 (W707Ni) e sili atu le maualuga nai lo le GER-N27L (W707). O le mea lea, i le tulaga o le malosi, GER-N27L (W707) o loʻo i le 490MPa grade electrode ma le maualalo le malosi. GER-N27 (W707Ni) o se tulaga, ma o le aʻafiaga o le faʻatinoga o le GER-N27L (W707) e fetaui lelei e sili atu nai lo GER-N27 (W707Ni), ae i faʻaoga faʻaoga, GER-N27L (W707) ma GER-N27 ( W707Ni) a'afiaga Ole su'ega e masani ona talia e tusa ai ma le fa'asino ole -70°C po'o le -75°C.

O le GER-N27L ma le GER-N27 e sili atu ona lelei tulaga uma pe a faʻapipiʻiina le ASME SA-203 GrA/B poʻo le 09MnNiDR uamea (e pei ona faʻaalia i le ata o loʻo i luga mo le faʻavaeina o le suʻisuʻi tuʻu saʻo o le lua eletise), ma e masani lava. fautuaina e le tatau ona sili atu le malosi laina uelo 35kJ / cm, ina ia maua se fausaga sili ona pulea e acicular ferrite. Pe a faʻaaogaina le GER-N27L (W707) i meafaigaluega e manaʻomia ai le tineia ma le faʻafefeteina o le vevela + togafitiga vevela, e masani lava ona maua ai le malosi o le aʻafiaga o le vevela, ae o le a le maua ai se malosi, ma o le malosi tensile e masani ona maualalo nai lo 500MPa; GER-N27L (W707) I le faaopoopo atu i olo, e faʻaaogaina foi i le 09MnNiDR uamea ethylene spherical tane, ae o le GER-N27 (W707Ni) e masani ona faʻaaogaina i totonu o koneteina maualalo-vevela e naʻo le manaʻomia o togafitiga vevela.
