420J1 420J2 umcu wentsimbi
Inkcazelo emfutshane:
I-420J1 kunye ne-420J2 iintambo zensimbi zimbini iintlobo eziqhelekileyo zezinto zensimbi ezingenasici ezizezoluhlu lwe-martensitic stainless steel series.Baye bahluke kwimichiza kunye neempawu.Nalu ushwankathelo lwento nganye:
1. I-420J1 intsimbi yensimbi engenasici: 420J1 yintsimbi ephantsi yekhabhoni enobunzima obuphezulu kunye namandla.Ukwakhiwa kweekhemikhali ngokuqhelekileyo kubandakanya malunga ne-0.16-0.25% yekhabhoni, malunga ne-1% ye-chromium, kunye neemali ezincinci ze-molybdenum.I-420J1 inika ukuxhathisa okulungileyo kokugqwala, ukusebenza kokusika, kunye neempawu zokugaya.Iqhele ukusetyenziselwa ukwenza iimela, izixhobo zotyando, iinxalenye zoomatshini, kunye nezinye izinto ezikwaziyo ukunxiba.
2. I-420J2 intsimbi yensimbi engenasici: 420J2 yintsimbi ephakathi kwekhabhoni enobunzima obuphezulu kunye nokumelana nokugqoka.Ukwakhiwa kweekhemikhali ngokuqhelekileyo kuqulethe malunga ne-0.26-0.35% yekhabhoni kunye ne-1% yechromium.I-420J2 inomxholo ophezulu wekhabhoni xa kuthelekiswa ne-420J1, okubangelwa ukwanda kobunzima kunye nokusebenza kokusika.Ihlala isetyenziselwa ukwenza iimela, iincakuba, izixhobo zotyando, imithombo, kunye namanye amalungu omatshini.
