Ubudala-Ukuqina Stainless Steel Forgings Bar
Inkcazelo emfutshane:
Ubunzima beminyaka yobudala, obubizwa ngokuba yi-precipitation hardening, yinkqubo yonyango yokushisa ephucula amandla kunye nobunzima be-alloys ezithile, kubandakanywa insimbi engenasici.Injongo ye-age-harding kukubangela imvula yeengqungquthela ezintle ngaphakathi kwe-matrix yensimbi engenasici, eyomeleza izinto eziphathekayo.
Ibha yokuQinisekisa yeNtsimbi eNgenaNsimbi yokuQinisekisa:
I-Forgings ngamalungu esinyithi abunjwe ngenkqubo yokubumba, apho izinto zifudunyezwa kwaye zibethelwe ngesando okanye zicinezelwe kwifom efunwayo.Iintsimbi zensimbi ezingenasici zihlala zikhethwa ngenxa yokuxhathisa ukubola, ukomelela, kunye nokuqina, zibenza zilungele izicelo ezahlukeneyo, kubandakanywa i-aerospace, i-oyile kunye negesi, kunye nokunye. isetyenziswa rhoqo kwizicelo apho ubude obuqhubekayo, obuthe ngqo bemathiriyeli bufuneka, njengolwakhiwo lwezakhiwo okanye njengemathiriyeli ekrwada yokusetyenzwa okongeziweyo.

Yintoni i-Precipitation Hardening Steel Stainless?
Imvula yenza lukhuni intsimbi engatyiwayo, edla ngokubizwa ngokuba yi "PH intsimbi estainless," luhlobo lwentsimbi engatyiwayo ehamba inkqubo ebizwa ngokuba yimvula eqina okanye ukuqina kweminyaka. Le nkqubo iphucula iimpawu zomatshini wezinto eziphathekayo, ngokukodwa amandla kunye nobunzima. Olona mvula luxhaphakileyo luqina intsimbi engenasici17-4 PH(I-ASTM A705 iBanga le-630), kodwa amanye amabakala, afana ne-15-5 PH kunye ne-13-8 PH, nawo awela kolu luhlu.I-Precipitation iqinisa i-stainless steels ngokuqhelekileyo ixutywe kunye nezinto ezifana ne-chromium, i-nickel, ubhedu, kwaye ngamanye amaxesha i-aluminium.
Yenziwa lukhuni njani imvula yentsimbi engatyiwayo?
Ubudala ukuqina kwensimbi engenasici kubandakanya inkqubo yamanyathelo amathathu. Ekuqaleni, izinto eziphathekayo zifumana unyango lwesisombululo esiphezulu, apho i-athomu ye-solute ichithwa, yenze isisombululo sesigaba esisodwa. Oku kukhokelela ekwakhiweni kweenuclei ezininzi ezincinci okanye "iindawo" kwintsimbi. Emva koko, ukupholisa ngokukhawuleza kwenzeka ngaphaya komda we-solubility, ukudala isisombululo esiqinileyo kwi-supersaturated kwi-metastable state.Kwinqanaba lokugqibela, isisombululo se-supersaturated sishushu kwiqondo lokushisa eliphakathi, ebangela imvula. Izinto eziphathekayo zigcinwa kule meko de zibe lukhuni. Ukuphumelela ukuqina kweminyaka kufuna ukuba ukubunjwa kwe-alloy kube ngaphakathi komda we-solubility, ukuqinisekisa ukusebenza kakuhle kwenkqubo.
Zeziphi iintlobo zentsimbi enemvula eyenziwe lukhuni?
I-precipitation-hardening steels iza kwiindidi ezahlukeneyo, nganye ilungiselelwe ukuhlangabezana neemfuno ezithile zokusebenza kunye nesicelo. Iindidi eziqhelekileyo ziquka i-17-4 PH, 15-5 PH, 13-8 PH, 17-7 PH, A-286, Custom 450, Custom 630 (17-4 PHMod), kunye neCarpenter Custom 455. Ezi ntsimbi zinika indibaniselwano yamandla aphezulu, ukumelana nokugqwala, kunye nokuqina, okubenza bafaneleke kumashishini ahlukeneyo afana ne-aerospace, i-automotive, unyango, kunye nokulungiswa kweekhemikhali. Ukukhethwa kwentsimbi yokuqina kwemvula kuxhomekeke kwizinto ezifana nokusingqongileyo kwesicelo, ukusebenza kwezinto eziphathekayo, kunye neenkcukacha zokuvelisa.
