Ibha Yensimbi Engagqwali 403 405 416
Incazelo emfushane:
Imigoqo yensimbi engagqwali ithola ukusetshenziswa ezimbonini ezahlukahlukene, okuhlanganisa ezokwakha, ezokukhiqiza, ezimoto, ezokuhamba ngezindiza, nokuningi.
Amabha Ensimbi Engagqwali:
Insimbi engagqwali 403 iyinsimbi engagqwali ye-martensitic enokwakheka okuhlanganisa i-chromium, i-nickel, kanye nenani elincane le-carbon. Yaziwa ngokumelana kwayo okuhle nokugqwala ezindaweni ezithambile, ukumelana nokushisa okufika ku-600°F (316°C), kanye namandla nokuqina okuhle. Insimbi engagqwali 405 iyinsimbi engagqwali ye-ferritic equkethe i-chromium kanye nenani elincane le-nickel. Inikeza ukumelana okuhle nokugqwala kanye nokwakheka. Ayimelani nokushisa njengezinye izinsimbi ezingagqwali futhi ngokuvamile isetshenziswa ezindaweni ezithambile kancane. Insimbi engagqwali 416 iyinsimbi engagqwali ye-martensitic enesulfure eyengeziwe, ethuthukisa ukusebenza kwayo. Inokumelana okuhle nokugqwala, amandla aphakathi, kanye nokusebenza kahle kakhulu. Ivame ukusetshenziswa ezindaweni lapho ukusebenza ngokukhululeka kanye nokumelana nokugqwala kubalulekile khona.
