I-9Cr18 ne-440C zombili izinhlobo zensimbi engagqwali ye-martensitic, okusho ukuthi zombili ziqiniswe ukwelashwa kokushisa futhi zaziwa ngamandla azo aphezulu kanye nokungagqwali.
9cr18 futhi440Cziyingxenye yensimbi engagqwali ye-martensitic, edume ngobulukhuni bazo obungavamile kanye nokumelana nokugqoka ngemva kokucisha, okubenza bafanelekele izicelo zokugqoka okuphezulu. Zombili izinto ezisetshenziswayo zingafinyelela amazinga okuqina e-HRC60° nangaphezulu ngokulandela ukwelashwa kokushisa. I-9Cr18 ibonakala ngokuqukethwe kwayo okuphezulu kwekhabhoni ne-chromium, iyenza ilungele ukukhiqiza izingxenye ezingaphansi kokuguga okuphezulu, imithwalo esindayo, kanye nezindawo ezingaboli, njengokulawula okuzenzakalelayo. izingxenye ze-valve. Kodwa-ke, isengozini yokungenwa yi-oxidation lapho ibhekene namanzi noma umhwamuko wamanzi, okwenza kudingeke ukuthi isetshenziswe ezindaweni lapho ukuthintana nomswakama kuncishisiwe.
Umehluko ekubunjweni kwamakhemikhali
| 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 |
Ngokufigqiwe,440C insimbi engagqwalingokuvamile inikeza ubulukhuni obuphakeme kanye nokumelana nokugqwala okungcono kancane uma kuqhathaniswa ne-9Cr18, kodwa zombili izinto zokusebenza zifanele uhla lwezinhlelo zokusebenza lapho ukusebenza okuphezulu nokuqina kubalulekile.
