409 430 439 441 443 isahani yicyuma
Ibisobanuro ku musaruro:
400 serie ibyuma bitagira umuyonga ni uruvange rwicyuma, karubone na chromium. Kuberako idafite nikel,
nicyuma kibika nikel kibika ibyuma, kizwi kandi nkicyuma. 400 serie idafite ibyuma idafite ibisanzwe
ibintu bya magnetique kubera imiterere ya martensitike hamwe nicyuma.
Ibyuma 400 byuma bitagira umuyonga bifite imbaraga zo guhangana nubushyuhe bwo hejuru, hamwe nubukanishi
imitungo irusheho kunozwa ugereranije nicyuma cya karubone. Ibyinshi 400 byuma bitagira umuyonga birashobora kuvurwa ubushyuhe.

Gusaba:
1. 409 ibyuma bidafite ingese: 409L ifite imbaraga zo guhangana nubushyuhe bwo hejuru, irashobora kugera kuri moteri ikora neza kandi
sisitemu yo gusohora, no kugabanya ubunini bwa sisitemu isohoka, ishobora kugabanya ibyuka bihumanya.
409L ifite igiciro gito, guhinduka neza, umusaruro mwinshi no gusimburwa byoroshye. Nibicuruzwa bishya bitangiza ibidukikije.
2. 430 ibyuma bidafite ingese: Kubishushanya inyubako, ibice byo gutwika lisansi, ibikoresho byo murugo, ibikoresho byo murugo.
430F nicyiciro cyicyuma gifite ibikoresho byo gukata kubuntu byongewe kumyuma 430, ikoreshwa cyane cyane mumisarani yikora, bolts na nuts.
3. 439 ibyuma bidafite ingese: Lifator, imbaho zo gushushanya escalator; ibishushanyo mbonera byubaka, nkibice byo gushushanya,
imiyoboro yubatswe; Sisitemu yimodoka ya sisitemu; imashini imesa imbere
4. 441 ibyuma bidafite ingese: Umuyoboro mwinshi, umuyoboro w'imbere, CONVERTER, nibindi bya sisitemu yo gusohora imodoka.
5. 443 ibyuma bidafite ingese: Ibyuma bitagira umwanda 443 ni ubwoko bwibyuma bya ferritic. Mubisanzwe bikoreshwa mugusimbuza 304.
Kurwanya ingese no gutunganya imikorere birakomeye kurenza 304, ariko igiciro kiri hasi. Irakoreshwa cyane muri
ibikoresho by'amashanyarazi, ibikoresho, ibikoresho byo mu gikoni, lift, amashyiga n'indi mirima.
