I-420j1 420j2 strip insimbi engenasici
Incazelo emfushane:
I-420j1 kanye ne-420j2 imichilo yensimbi engenasici iyizinhlobo ezimbili ezivamile zezinto ezingenasici ezingezochungechunge lwensimbi engagqwali. Banomehluko othile ekubumbeni amakhemikhali nezimpawu. Nasi umbono omfushane ngakunye:
1. 420j1 strip yensimbi engenasici: 420j1 insimbi ephansi yekhabhoni enobulukhuni obuphezulu namandla. Ukwakheka kwalo kwamakhemikhali kuvame ukufaka phakathi kuka-0.16-0.25% carbon, cishe i-1% chromium, kanye namanani amancane we-molybdenum. I-420j1 inikezela ukumelana kahle kokugqwala, ukusika ukusebenza, kanye nezindawo zokugaya. Kuvame ukusetshenziselwa ukwenza imimese, amathuluzi okuhlinza, izingxenye zemishini, kanye nezinye izinhlelo zokusebenza ezivinjelwe.
2. Ukwakheka kwalo kwamakhemikhali kuvame ukuqukethe cishe ngo-0.26-0.35% Carbon kanye ne-1% Chromium. I-420j2 inokuqukethwe okuphezulu kwe-carbon kuqhathaniswa ne-420j1, okuholela ekukhuliseni ubulukhuni nokusika ukusebenza. Kusetshenziswa kaningi ukuthola imimese yokukhiqiza, ama-blade, amathuluzi okuhlinza, iziphethu, kanye nezinye izingxenye zomshini.
