Intsimbi engatyiwa 409

I-409 insimbi engenasici yintsimbi yeFerritic enikezela ngeempawu ezilungileyo zoomatshini kunye nokumelana nobushushu obuphezulu be-corrosion. Ngokuqhelekileyo ithathwa njengentsimbi ye-chromium, enezicelo kwiinkqubo zokukhupha iimoto kunye nezicelo ezifuna ukuwelda.

Iintsimbi ze-409 nazo zifumaneka kwiifom ezizinzileyo kakhulu, ezifana namabakala S40930, S40920 kunye ne-S40910. Ukuzinza kwala mabanga kubonelelwa kubukho be-niobium, i-titanium, okanye zombini, ekubunjweni kweentsimbi.

AmaBanga anokuthi abekhona

IBanga	Iipropati
3CR12	Kulula ukuwelda kunye nokunganyangeki kakuhle komhlwa. Amacandelo anzima afumaneka lula xa kuthelekiswa ne-409.
304	Ukumelana nokushisa okuphezulu kunye nokumelana nokubola. IBanga lama-304 liyabiza.
321	Ukumelana nobushushu obungcono xa kuthelekiswa ne-304 okanye i-409.
Intsimbi yeAluminized	Ixabiso eliphantsi kunebakala lama-409 lentsimbi engenasici, kodwa lincinci ukumelana nokukhupha iigesi.
