1, umubiri wicyuma ibikoresho bidafite ingese

Mbere ya byose, ibyuma bidafite ingese ya moderi 430 ni ibyuma bisanzwe bya chromium.Kurwanya ruswa no kurwanya ubushyuhe nibyiza kuruta umugozi wicyitegererezo 410, kandi ni magnetique, ariko ntishobora gushimangirwa no kuvura ubushyuhe.Kubwibyo, ibyuma bidafite ingese yicyitegererezo 430 birakwiriye cyane kubirwanya ruswa no kurwanya ubushyuhe, kandi ubukana bwabwo ntabwo ari bwiza cyane.

2, martensitike idafite ibyuma

Ibyuma bidafite ingese ya moderi 410 na moderi 416 ku isoko birashobora gushimangirwa no kuvura ubushyuhe.Nyuma yo kuvura ubushyuhe bumaze gushimangirwa, ubukana bwibyuma bitagira umuyonga muri rusange ni 32 kugeza 45HRC, kandi imashini yicyuma nayo idafite akamaro.Amazi ya sulferi yibikoresho byicyuma cya moderi ya 416 ni muremure cyane, kandi ni mubikoresho byibyuma byoroshye gukata kandi byoroshye gukata.

3. Icyuma cya Austenitike

Amazina yacu ya screw na moderi ni 302.303.304 na 305. Ibyo bita 18-8 austenitis ibyuma bidafite ibyuma muri rusange bifite ubu buryo bune.Kurwanya ruswa hamwe nubukanishi byombi birasa cyane, ukoresheje uburyo bwo gukora uburyo bwo gukora ibyuma bitagira umuyonga ntabwo ari kimwe rwose, kandi UKORESHE uburyo bwo kumenya ibisobanuro byacyo hamwe nimiterere yibyuma bitagira umwanda, kimwe no kumenya umubare, kuri ikozwe mu byuma bitagira umuyonga iyo itezimbere nyuma yo kuvura ubushyuhe, urwego rwimbaraga zayo rushobora kugera kuri 4.7.
