EN10025-3 S420N icyiciro cyicyuma

Icyapa cya S420N
Kwemeza bisanzwe: EN10025-3

Kugurisha icyiciro cyicyuma: S275N, S355N, S420N, S460N, S275NL, S355NL, S420NL, icyapa cya S460NL

Icyapa cya S420N

S420N ibyuma nicyiza cyiza cyo gusudira urwego rwicyuma. Ibisabwa rusange kugirango arc gusudira ibyuma byerekanwe bigomba gutangwa muri EN 1011-2.
Gereranya S355N, S420N icyiciro cyicyuma gifite umusaruro mwinshi nimbaraga zikomeye. Urwego rungana rwa S420N ni S420M.

Icyuma cya Gnee gifite uburambe mu gukora S420N. twafatanije nuruganda rwa wuyang rwa HBIS kugirango tubyare uburebure bwa 300mm muri tekinike ya electroslag. Inyungu zacu nuko dushobora gutanga ibicuruzwa mugihe cyo gutanga byihuse, ndetse no mubisahani imwe mubisobanuro bisanzwe.

Ibyerekeranye na S420N ibyuma birambuye amakuru ， nyamuneka reba itariki ya tekiniki ikurikira.

Imiti niyinshi murwego rwo gusesengura ibicuruzwa:

Kubindi bisobanuro muri S420N ibyemezo byubuziranenge cyangwa kubaza mubisobanuro byatanzwe mumarushanwa, nyamuneka twandikire ukoresheje imeri.
