Ma GER-N27L ndi GER-N27 omwe timapanga ndi maelekitirodi achitsulo otsika a haidrojeni okhala ndi sodium okhala ndi Ni okwana 2.5%, omwe nthawi zambiri amagwiritsidwa ntchito powotcherera zitsulo za ASME SA-203 GrA/B ndi 09MnNiDR. Mitundu ya GER-N27L ndi GER-N27 yomwe ikugwiritsa ntchito GB/T5117-2012 pano ndi E5015-N5 P/E5015-G P ndi E5515-N5 P motsatana, zomwe zimagwirizana ndi magiredi a "Welding Equipment Product Handbook" yofalitsidwa ndi Machinery. Industry Press. Kwa W707 ndi W707Ni, katundu wakuthupi ndi mankhwala a chitsulo choyikidwa pa maelekitirodi awiriwa amafananizidwa motere.

Zitha kuwoneka kuchokera patebulo lomwe lili pamwambapa kuti mankhwala opangidwa ndi C ndi Si a zitsulo zoyikidwa za GER-N27 (W707Ni) ndizokwera pang'ono kuposa za GER-N27L (W707). Choncho, ponena za mphamvu, GER-N27L (W707) ndi ya 490MPa grade electrode yokhala ndi mphamvu zochepa. GER-N27 (W707Ni) ndi mulingo, ndipo magwiridwe antchito a GER-N27L (W707) ndi abwinoko pang'ono kuposa GER-N27 (W707Ni), koma pamagwiritsidwe ntchito, GER-N27L (W707) ndi GER-N27 ( W707Ni) zotsatira Mayeso nthawi zambiri amavomerezedwa molingana ndi -70°C kapena -75°C.

GER-N27L ndi GER-N27 ndi zabwino zonse udindo weldability pamene kuwotcherera ASME SA-203 GrA/B kapena 09MnNiDR zitsulo (monga taonera pamwamba chithunzi mapangidwe ofukula kuwotcherera msoko wa maelekitirodi awiri), ndipo nthawi zambiri. analimbikitsa kuti kuwotcherera mzere mphamvu sayenera upambana 35kJ / masentimita, kuti apeze dongosolo kwambiri lolamulidwa ndi acicular ferrite. GER-N27L (W707) ikagwiritsidwa ntchito pazida zomwe zimafunikira kuzimitsa ndi kutentha kutentha + kutentha kwa annealing, nthawi zambiri zimakhala zolimba kwambiri, koma zimataya mphamvu, ndipo mphamvu zamakokedwe nthawi zambiri zimakhala zotsika kuposa. 500MPa; GER-N27L (W707) Kuphatikiza pa nsanja, imagwiritsidwanso ntchito m'matangi a 09MnNiDR zitsulo za ethylene spherical, pomwe GER-N27 (W707Ni) nthawi zambiri amagwiritsidwa ntchito m'mitsuko yocheperako yomwe imafunikira chithandizo cha kutentha kwa annealing. Zotsatirazi zipereka zitsanzo za kagwiritsidwe ntchito ka GER-N27L ndi GER-N27 .
