    Iithegi zeMveliso

    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, amalungu omatshini, 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.
