GER-N27L thiab GER-N27 peb tsim yog ob qho tib si qis-hydrogen sodium-coated low-temperature steel electrodes nrog Ni cov ntsiab lus ntawm 2.5%, uas feem ntau yog siv rau vuam ASME SA-203 GrA / B thiab 09MnNiDR steels. Cov qauv ntawm GER-N27L thiab GER-N27 tam sim no siv GB / T5117-2012 yog E5015-N5 P / E5015-G P thiab E5515-N5 P feem, uas sib haum rau cov qib ntawm "Vuam Cov Khoom Siv Khoom Siv" luam tawm los ntawm Machinery Kev Lag Luam Xovxwm. Rau W707 thiab W707Ni, lub cev thiab tshuaj lom neeg cov khoom ntawm cov hlau tso ntawm ob lub electrodes yog muab piv raws li hauv qab no.

Nws tuaj yeem pom los ntawm cov lus saum toj no tias cov tshuaj muaj pes tsawg leeg C thiab Si ntawm cov hlau tso ntawm GER-N27 (W707Ni) yog me ntsis siab dua cov GER-N27L (W707). Yog li ntawd, hais txog lub zog, GER-N27L (W707) belongs rau 490MPa qib electrode nrog lub zog tensile tsawg. GER-N27 (W707Ni) yog ib theem, thiab qhov cuam tshuam kev ua tau zoo ntawm qhov sib thooj GER-N27L (W707) yog me ntsis zoo dua GER-N27 (W707Ni), tab sis hauv kev siv tswv yim, GER-N27L (W707) thiab GER-N27 ( W707Ni) cuam tshuam Kev ntsuas feem ntau lees txais raws li qhov ntsuas ntawm -70 ° C lossis -75 ° C.

GER-N27L thiab GER-N27 muaj qhov zoo tshaj plaws ntawm txhua txoj haujlwm weldability thaum vuam ASME SA-203 GrA / B lossis 09MnNiDR steel (raws li qhia hauv daim duab saum toj no rau kev tsim cov ntsug vuam seam ntawm ob lub electrodes), thiab nws yog feem ntau pom zoo tias cov vuam kab hluav taws xob yuav tsum tsis pub tshaj 35kJ / cm, thiaj li yuav tau txais cov qauv zoo tshaj plaws los ntawm acicular ferrite. Thaum GER-N27L (W707) tau siv rau cov khoom siv uas xav tau kev kho cua sov thiab kev kho cua sov + kev kho cua sov, feem ntau yog kom tau txais qhov zoo ntawm qhov kub thiab txias, tab sis nws yuav poob qee lub zog, thiab lub zog tensile feem ntau qis dua. 500MPa; GER-N27L (W707) Ntxiv rau cov yees, nws kuj tseem siv hauv 09MnNiDR steel ethylene spherical tso tsheb hlau luam, thaum GER-N27 (W707Ni) feem ntau siv hauv cov thawv kub uas tsuas yog xav tau kev kho cua sov. Cov hauv qab no yuav muab piv txwv ntawm daim ntawv thov thiab lwm yam kev ua tau zoo ntawm GER-N27L thiab GER-N27 .
