GER-N27L iyo GER-N27 ee aanu soo saarno labaduba waa birta birta ah ee heerkulka hooseeya ee sodium-dahaarka leh oo leh Ni content 2.5%, kuwaas oo inta badan loo isticmaalo alxanka ASME SA-203 GRA/B iyo 09MnNiDR birta.Moodooyinka GER-N27L iyo GER-N27 ee hadda fulinaya GB/T5117-2012 waa E5015-N5 P/E5015-G P iyo E5515-N5 P siday u kala horreeyaan, kuwaas oo u dhigma darajooyinka "Buug-gacmeedka Alaabta Alxanka" ee ay daabacday Machinery Saxaafadda Warshadaha.W707 iyo W707Ni, sifooyinka jidheed iyo kiimikaad ee birta kaydsan ee labada electrodes ayaa la barbardhigay sida soo socota.

Waxaa laga arki karaa shaxda kore in isku dhafka kiimikada C iyo Si ee birta kaydsan ee GER-N27 (W707Ni) ay waxyar ka sarreeyaan kuwa GER-N27L (W707).Sidaa darteed, marka la eego xoogga, GER-N27L (W707) waxay ka tirsan tahay korantada darajada 490MPa oo leh quwad jilicsan oo hooseeya.GER-N27 (W707Ni) waa heer, iyo waxqabadka saamaynta GER-N27L (W707) u dhiganta waa wax yar ka fiican GER-N27 (W707Ni), laakiin codsiyada la taaban karo, GER-N27L (W707) iyo GER-N27 ( W707Ni) Saamaynta Imtixaanka guud ahaan waa la aqbalay iyadoo loo eegayo tusmada -70°C ama -75°C.

GER-N27L iyo GER-N27 waxay leeyihiin weldability heer sare ah oo dhan marka alxanka ASME SA-203 GrA/B ama 09MnNiDR birta (sida ku cad shaxanka kor ku xusan ee formation of tolmo alxanka toosan ee labada electrodes), iyo guud ahaan waa. Waxaa lagu taliyay in tamarta xariiqda alxanka aysan ka badneyn 35kJ/cm, si loo helo qaab dhismeed aad u wanaagsan oo ay maamusho ferrite acicular.Marka GER-N27L (W707) lagu dabaqo qalabka u baahan deminta iyo daawaynta kulaylka + dawaynta kulaylka, sida caadiga ah waa in la helo adkaysiga heerkulka hoose ee ka wanaagsan, laakiin waxay lumin doontaa xoogaa xoogaa xoog ah, iyo xoogga adkaysiga guud ahaan wuu ka hooseeyaa 500MPa;GER-N27L (W707) Marka laga soo tago munaaradaha, waxaa sidoo kale loo isticmaalaa 09MnNiDR birta ethylene taangiyada, halka GER-N27 (W707Ni) inta badan lagu isticmaalo weelasha heerkulku hooseeyo oo kaliya u baahan daaweynta kulaylka.Kuwa soo socdaa waxay ku siin doonaan tusaalayaal codsiga iyo waxqabadka la xidhiidha GER-N27L iyo GER-N27 .
