Ibha eyisicaba yensimbi engagqwali engu-440Ciwumkhiqizo wensimbi engagqwali wekhwalithi ephezulu owaziwa ngenhlanganisela yawo eyingqayizivele yokumelana nokuguguleka kanye nokumelana nokugqwala. Ingowomndeni wensimbi engagqwali we-martensitic futhi isetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yokusebenza kwayo okuphezulu.

Nazi ezinye izinto ezibalulekile zokwethula ibha eyisicaba yensimbi engagqwali engu-440C:
1. Ukwakheka: Ibha eyisicaba yensimbi engagqwali engu-440C yakhiwe ngokuyinhloko nge-chromium (16-18%), i-carbon (0.95-1.20%), kanye nenani elincane lezinye izinto ezifana ne-manganese, i-silicon, ne-molybdenum.
2. Ukumelana Nokugqokwa: Ibha eyisicaba yensimbi engagqwali engu-440C idume ngokumelana kwayo nokugqokwa okuvelele, okwenza ifaneleke ukusetshenziswa kwezinto ezihudulayo, amathuluzi okusika, amabheringi, kanye nezingxenye ezingagugi.
3. Ukumelana Nokugqwala: Naphezu kokuba yinsimbi engagqwali enekhabhoni ephezulu, i-440C ikhombisa ukumelana okuhle nokugqwala.
4. Ukuqina Nokuqina: Ibha eyisicaba yensimbi engagqwali engu-440C inobulukhuni obuhle kakhulu namandla aphezulu, ihlinzeka ngokuqina nokuphila isikhathi eside ekusetshenzisweni okudingakalayo.
