Njengensimbi yesakhiwo se-alloy yekhwalithi ephezulu, insimbi engu-20CrMn inochungechunge lwezakhiwo ezinhle kakhulu futhi isetshenziswa kabanzi emikhakheni eminingi. Egameni layo, “20″ imele okuqukethwe kwe-chromium okungaba ngu-20%, futhi “Mn” imele okuqukethwe kwemanganese okungaba ngu-1%. Ukwengezwa kwalezi zici kunikeza insimbi engu-20CrMn izakhiwo ezihlukile zemishini nokumelana nokugqoka.

Okokuqala, izici zokusebenza zensimbi engu-20CrMn
Insimbi ye-20CrMn inezici ezilandelayo ezibalulekile zokusebenza:
1. Amandla amahle kakhulu nokuqina: Insimbi engu-20CrMn ingathola amandla aphakeme nokuqina ngemva kokwelashwa okufanele kokushisa, futhi ifanele izikhathi ezinengcindezi ephezulu kanye nemithwalo enomthelela.
2. Ukumelana nokugqokwa okuhle: Ngenxa yobukhona bezakhi ezifana ne-chromium ne-manganese, insimbi engu-20CrMn inokumelana nokugqokwa okuhle kakhulu futhi ifanele ukukhiqiza izingxenye ezingagugi njengamagiya, ama-bearings, njll.
3. Ukusebenza okuhle kakhulu kokwelashwa kokushisa: Insimbi engu-20CrMn ingathola kalula izakhiwo ezidingekayo ngomshini wokushisa, inokuguquguquka okuqinile, futhi ingahlangabezana nezidingo zama-workpieces ahlukene.

Okwesibili, inkambu yesicelo se-20CrMn steel
Insimbi ye-20CrMn inohlu olubanzi lwezinhlelo zokusebenza emkhakheni wezimboni, ikakhulukazi kufaka phakathi kodwa kungagcini kulezi zici ezilandelayo:
1. Ukukhiqizwa kwemishini: Insimbi engu-20CrMn ivame ukusetshenziselwa ukwenza izingxenye ezihlukahlukene zemishini, njengamagiya, izinsimbi zokudlulisela, njll. Amandla ayo amahle kakhulu kanye nokumelana nokugqoka kwenza idume emkhakheni wokukhiqiza imishini.
2. Ukwenziwa kwezimoto: Embonini yezimoto, insimbi engu-20CrMn ivamise ukusetshenziselwa ukukhiqiza izingxenye zokudlulisela, ezifana namagiya, ama-crankshafts, njll., ukuze kudlale izinzuzo zayo ezinhle kakhulu zokumelana nokugqokwa namandla.
3. Inkambu ye-Aerospace: Ngenxa yokuthi insimbi engu-20CrMn inokusebenza okuhle kokwelashwa kokushisa namandla aphezulu, iphinde yasetshenziswa kabanzi emkhakheni we-aerospace ukwenza izingxenye ezihlukahlukene zamandla aphezulu.
4. Imishini yobunjiniyela: Insimbi engu-20CrMn iphinde isetshenziswe kabanzi ekukhiqizeni imishini yobunjiniyela, esetshenziselwa ukukhiqiza izingxenye ezingagugi ezifana nezimba kanye nezilayishi ukuze zibhekane nezimo zokusebenza ezinokhahlo kanye nemithwalo yemisebenzi yamafrikhwensi aphezulu.

Kafushane, insimbi engu-20CrMn isetshenziswa kabanzi emikhakheni eminingi efana nokukhiqizwa kwemishini, ukukhiqizwa kwezimoto, i-aerospace, nemishini yobunjiniyela ngenxa yamandla ayo amangalisayo, ukuqina, nokumelana nokugqokwa, futhi isibe ngenye yezinto ezibalulekile ezibalulekile kule mikhakha.
