420J1 420J2 umucu wensimbi engagqwali
Incazelo emfushane:
I-420J1 kanye ne-420J2 yensimbi engagqwali izinhlobo ezimbili ezivamile zezinto zensimbi engagqwali eziyingxenye yochungechunge lwensimbi engenasici ye-martensitic.Banomehluko othile ekubunjweni kwamakhemikhali nezici.Nakhu okufingqiwe ngakunye:
1. 420J1 insimbi engagqwali: 420J1 iyinsimbi engenasikhabhoni ephansi enobulukhuni obuphezulu namandla.Ukwakheka kwayo kwamakhemikhali ngokuvamile kuhlanganisa cishe u-0.16-0.25% wekhabhoni, cishe u-1% we-chromium, kanye namanani amancane e-molybdenum.I-420J1 inikeza ukumelana nokugqwala okuhle, ukusebenza kokusika, nezakhiwo zokugaya.Ivamise ukusetshenziselwa ukwenza imimese, amathuluzi okuhlinza, izingxenye eziwumshini, nezinye izinhlelo zokusebenza ezingagugi.
2. I-420J2 yensimbi engagqwali: I-420J2 iyinsimbi engenasikhabhoni ephakathi enobunzima obuphezulu nokumelana nokugqoka.Ukwakheka kwayo kwamakhemikhali ngokuvamile kuqukethe cishe u-0.26-0.35% wekhabhoni kanye ne-chromium engu-1%.I-420J2 inokuqukethwe kwekhabhoni ephezulu uma kuqhathaniswa ne-420J1, okuholela ekwandeni kokuqina nokusebenza kokusika.Ivamise ukusetshenziselwa ukukhiqiza imimese, izindwani, amathuluzi okuhlinza, iziphethu, nezinye izingxenye zemishini.
