Ibha yentsimbi engagqwaliyo engu-440C
Inkcazo emfutshane:
Intsimbi engagqwaliyo ye-440C yintsimbi engagqwaliyo ye-martensitic enekhabhoni ephezulu eyaziwa ngokuba lukhuni kwayo, ukumelana nokuguguleka, kunye nokumelana nokugqwala.
Iibhari zentsimbi engagqwaliyo ezingama-440C:
Intsimbi engagqwaliyo ye-440C inokuqina ukuze ifikelele kumanqanaba aphezulu obunzima, ngokuqhelekileyo malunga ne-58-60 HRC (isikali sobunzima beRockwell). Ikwi-400 series yeentsimbi ezingagqwaliyo, ezibonakala ngokuba nomxholo ophezulu wekhabhoni, ngokuqhelekileyo malunga ne-0.60-1.20%, kunye nokumelana nokugqwala okuphakathi. Inokumelana okuhle kokuguguleka, okwenza ukuba ifaneleke kwizicelo ezifana neebheringi, izixhobo zokusika, izixhobo zotyando, kunye nezixhobo zevalvu. Nangona ingenakumelana nokugqwala njengeentsimbi ezingagqwaliyo ze-austenitic (umz., 304, 316), i-440C inika ukumelana okuhle nokugqwala kwiindawo ezithambileyo. Iyakwazi ukumelana nokugqwala kunezinye iintsimbi ezinekhabhoni ephezulu ngenxa yomxholo wayo we-chromium. Intsimbi engagqwali ye-440C inokulungiswa ngobushushu ukuze ifikelele kwiimpawu zoomatshini ezifunekayo.

Yintoni i-440C Stainless Steel?
Intsimbi engagqwaliyo ye-440C inika ulungelelwano lokuxhathisa ukugqwala okuhle kunye nokuxhathisa ukugqwala okuphakathi kwiindawo ezithambileyo, kunye nokuqina okugqwesileyo. Ifana ne-440B grade kodwa inomxholo wekhabhoni ophezulu kancinci, okubangela ubunzima obuphezulu kodwa ukumelana nokugqwala okuncinci kuncitshiswe xa kuthelekiswa ne-440B. Ingafikelela kubunzima obufikelela kwi-60 Rockwell HRC kwaye imelana nokugqwala kwiindawo eziqhelekileyo zasekhaya kunye nezoshishino ezithambileyo, kunye nokumelana okuphezulu okufikelelwa ngaphantsi kwama-400°C obushushu bokufudumeza. Ukulungiswa komphezulu kubalulekile ekuchaseni ukugqwala okungcono, nto leyo ebangela ukuba kususwe isikali, izinto zokuthambisa, amasuntswana angaphandle, kunye neengubo. Umxholo wayo ophezulu wekhabhoni uvumela ukucutshungulwa okufana nomgangatho wentsimbi ekhawulezayo e-annealed.
Isicelo seBar yeStainless Steel Round ye-440C:
Iibhari ezingqukuva zentsimbi engagqwaliyo ezingama-440C zisetyenziswa kakhulu ekwenzeni iimela, iibheringi, izixhobo zokusebenzisa izixhobo kunye nokusika, izixhobo zonyango, izinto zevalvu, kunye nezixhobo zoshishino, apho ubunzima bazo obuphezulu, ukumelana nokuguguleka, kunye nokumelana nokugqwala okuphakathi kuzenza zibe lukhetho olufanelekileyo kwiindawo ezibalulekileyo ezifuna ukusebenza kakuhle kunye nokuqina ixesha elide.
Ukuwelda kweNtsimbi Engagqwaliyo 440C:
Ngenxa yobunzima bayo obuphezulu kunye nokulula kokuqinisa umoya, ukuwelda kwentsimbi engagqwaliyo ye-440C akwenzeki rhoqo. Nangona kunjalo, ukuba ukuwelda kuyimfuneko, kucetyiswa ukuba kufudunyezwe kwangaphambili izinto ukuya kuma-260°C (500°F) kwaye kwenziwe unyango lokufunxa emva kokuwelda kwi-732-760°C (1350-1400°F) iiyure ezi-6, kulandele ukupholisa kancinci kwesithando somlilo ukuthintela ukuqhekeka. Ukuqinisekisa iipropati ezifanayo zoomatshini kwi-weld njengakwintsimbi esisiseko, kufuneka kusetyenziswe izinto ezisetyenziswayo zokuwelda ezinomxube ofanayo. Kungenjalo, i-AWS E/ER309 inokuthathwa njengokhetho olufanelekileyo.
