Ibyuma bitagira umwanda 409

409 ibyuma bidafite ingese nicyuma cya Ferritic gitanga ibikoresho byiza byubukanishi hamwe nubushyuhe bwo hejuru bwo kwangirika. Mubisanzwe bifatwa nkicyuma cya chromium kitagira ibyuma, hamwe nibisabwa muri sisitemu yo gusohora ibinyabiziga hamwe na porogaramu zisaba gusudira.

Ibyuma 409 nabyo biraboneka muburyo butajegajega cyane, nk'amanota S40930, S40920 na S40910. Iterambere ryibi byiciro ritangwa no kuba niobium, titanium, cyangwa byombi, mubigize ibyuma.

Ibishoboka Ibindi Byiciro

Icyiciro	Ibyiza
3CR12	Biroroshye gusudira kandi birwanya ruswa. Ibice biremereye biraboneka byoroshye mugihe ugereranije na 409.
304	Kurwanya ubushyuhe bwinshi no kurwanya ruswa. Icyiciro cya 304 gihenze.
321	Kurwanya ubushyuhe bwiza iyo ugereranije na 304 cyangwa 409.
Ibyuma bya aluminiyumu	Guhendutse kurenza icyiciro cya 409 ibyuma bitagira umwanda, ariko ntibishobora kwihanganira imyuka ihumanya.
