440 ishidi lensimbi engagqwali

Izinsimbi ezingagqwali zingama-high-alloy steels anokumelana nokugqwala okuphezulu uma kuqhathaniswa nezinye izinsimbi ngenxa yokuba khona kwenani elikhulu le-chromium. Ngokusekelwe ekwakhiweni kwawo okucwebezelayo, ahlukaniswe abe izinhlobo ezintathu ezifana nezinsimbi ze-ferritic, austenitic, ne-martensitic. Elinye iqembu lezinsimbi ezingenasici yizinsimbi eziqiniswe yimvula. Ziyinhlanganisela yezinsimbi ze-martensitic kanye ne-austenitic. Ibanga 440C insimbi engagqwali iyinsimbi engagqwali ye-carbon martensitic ephezulu. Inamandla aphezulu, ukumelana nokugqwala okumaphakathi, nobulukhuni obuhle nokumelana nokugqoka. IBanga 440C liyakwazi ukuthola, ngemva kokwelashwa kokushisa, amandla aphakeme kakhulu, ubulukhuni kanye nokumelana nokugqoka kwawo wonke ama-alloys angenasici. Okuqukethwe kwayo kwekhabhoni ephezulu kakhulu kunesibopho salezi zici, ezenza i-440C ifanele ikakhulukazi izinhlelo zokusebenza ezifana namabheringi ebhola nezingxenye zamavalvu.
Ulwazi Lomkhiqizo
