I-9Cr18 kunye ne-440C zombini iindidi zentsimbi ye-martensitic stainless, oku kuthetha ukuba zombini ziqiniswe ngonyango lobushushu kwaye ziyaziwa ngamandla abo aphezulu kunye nokuxhathisa ukubola.
9Cr18 kunye440Cziyinxalenye yodidi lwe-martensitic steels stainless, ezaziwayo ngobulukhuni bazo obukhethekileyo kunye nokunxiba ukuxhathisa emva kokucima, okubenza bafanelekele izicelo zokunxiba okuphezulu. Zombini izixhobo zinokufikelela kumanqanaba obunzima be-HRC60 ° nangaphezulu kokulandela unyango lobushushu. I-9Cr18 ibonakaliswe ngumxholo wayo wekhabhoni ephezulu kunye nekhromium, iyenza ilungele ukuvelisa amacandelo aphantsi kokunxiba okuphezulu, imithwalo enzima, kunye neendawo ezingangcolisiyo, ezifana nolawulo oluzenzekelayo. iindawo zevalvu. Nangona kunjalo, ichaphazeleka kwi-oxidation xa isesichengeni samanzi okanye umphunga wamanzi, oko kuthetha ukuba kufuneka isetyenziswe kwindawo apho ukudibana nokufuma kuncitshisiwe.
Umahluko ekubunjweni kweekhemikhali
| IBanga | C | Cr | Mn | Si | P | S | Ni | Mo |
| 9Kr18 | 0.95-1.2 | 17.0-19.0 | 1.0 | 1.0 | 0.035 | 0.030 | 0.60 | 0.75 |
| 440C | 0.95-1.2 | 16.0-18.0 | 1.0 | 1.0 | 0.040 | 0.030 | 0.60 | 0.75 |
Isishwankathelo,440C intsimbi engenasiciNgokuqhelekileyo ibonelela ngobulukhuni obuphezulu kunye nokumelana nokukhula okungcono kancinci xa kuthelekiswa ne-9Cr18, kodwa zombini izixhobo zifanelekile kuluhlu lwezicelo apho ukusebenza okuphezulu kunye nokuqina kubalulekile.
