GER-N27L na GER-N27 dukora byombi ni hydrogène nkeya ya sodium ikozweho na electrode yo hasi yubushyuhe bwo hasi ifite Ni ya 2,5%, ikoreshwa kenshi mu gusudira ASME SA-203 GrA / B na 09MnNiDR. Moderi ya GER-N27L na GER-N27 muri iki gihe ishyira mu bikorwa GB / T5117-2012 ni E5015-N5 P / E5015-G P na E5515-N5 P, ibyo bikaba bihuye n’amanota ya "Welding Materials Products Handbook" yasohowe na Machinery Inganda. Kuri W707 na W707Ni, imiterere yumubiri nubumara byicyuma cyabitswe cya electrode zombi zigereranijwe kuburyo bukurikira.

Birashobora kugaragara kumeza yavuzwe haruguru ko imiti ya C na Si yicyuma cyabitswe cya GER-N27 (W707Ni) kiri hejuru gato ugereranije na GER-N27L (W707). Kubwibyo, kubijyanye nimbaraga, GER-N27L (W707) ni ya electrode yo mu rwego rwa 490MPa ifite imbaraga nke. GER-N27 (W707Ni) ni urwego, kandi imikorere yingaruka za GER-N27L ihuye (W707) iruta gato GER-N27 (W707Ni), ariko mubikorwa bifatika, GER-N27L (W707) na GER-N27 ( W707Ni) ingaruka Ikizamini cyemewe muri rusange ukurikije igipimo cya -70 ° C cyangwa -75 ° C.

GER-N27L na GER-N27 bifite imyanya myiza cyane yo gusudira mugihe cyo gusudira ASME SA-203 GrA / B cyangwa 09MnNiDR ibyuma (nkuko bigaragara mumashusho yavuzwe haruguru kugirango habeho icyerekezo cyo gusudira gihagaritse cya electrode ebyiri), kandi muri rusange ni rusange yasabye ko umurongo wo gusudira utagomba kurenza 35kJ / cm, kugirango ubone imiterere myiza yiganjemo acicular ferrite. Iyo GER-N27L (W707) ikoreshwa mubikoresho bikenera kuzimya no kugabanya ubushyuhe bwo kuvura ubushyuhe + bwo kuvura ubushyuhe, mubisanzwe ni ukubona ubukana bwubushyuhe bwo hasi, ariko bizatakaza imbaraga, kandi imbaraga za tensile muri rusange ziri munsi ugereranije 500MPa; GER-N27L (W707) Usibye iminara, ikoreshwa no mu bigega bya 09MnNiDR ibyuma bya etilene spherical tanks, mu gihe GER-N27 (W707Ni) ikoreshwa kenshi mu bikoresho bifite ubushyuhe buke bikenera gusa kuvura ubushyuhe. Ibikurikira bizatanga ingero zo gusaba hamwe nibikorwa bijyanye na GER-N27L na GER-N27.
