Insimbi engagqwali 409

I-409 insimbi engagqwali iyinsimbi yeFerritic enikeza izakhiwo ezinhle zokuwumshini kanye nokumelana nokugqwala okusezingeni eliphezulu. Ivamise ukubhekwa njengensimbi engagqwali ye-chromium, esebenza kumasistimu wokukhipha umoya wezimoto nezinhlelo zokusebenza ezidinga ukushiselwa.

Izinsimbi ezingama-409 ziyatholakala futhi ngamafomu azinzile kakhulu, njengamabanga S40930, S40920 kanye ne-S40910. Ukuzinza kwala mabanga kunikezwa ukuba khona kwe-niobium, i-titanium, noma kokubili, ekubunjweni kwezinsimbi.

Amanye Amabanga Angenzeka

Ibanga	Izakhiwo
3CR12	Kulula ukushisela futhi ukumelana nokugqwala okuhle. Izigaba ezinzima zitholakala kalula uma ziqhathaniswa ne-409.
304	Ukumelana nokushisa okuphezulu nokumelana nokugqwala. Ibanga lama-304 liyabiza.
321	Ukumelana nokushisa okungcono uma kuqhathaniswa no-304 noma 409.
Insimbi ye-aluminium	Ishibhile kune-grade 409 yensimbi engagqwali, kodwa imelana kancane namagesi akhipha umoya.
