440C Stainless Steel Bar
Inkcazelo emfutshane:
I-440C insimbi engenasici yintsimbi ye-carbon martensitic ephezulu eyaziwayo ngokuqina kwayo okugqwesileyo, ukuxhathisa ukunxiba, kunye nokumelana nomhlwa.
IiBha zeNtsimbi engama-440C:
I-440C insimbi engenasici inokuthi iqiniswe ukufezekisa amanqanaba aphezulu obunzima, ngokuqhelekileyo malunga ne-58-60 HRC (i-Rockwell hardness scale) .Iyi-400 series of steels stainless steels, ezibonakaliswe ngokuba nomxholo ophezulu wekhabhoni, ngokuqhelekileyo malunga ne-0.60-1.20%, kunye ne-corrosion ephakathi, kunye nezixhobo ezifanelekileyo zokuxilisa, ukwenza ukuba ibhere ixhathise, ikwazi ukumelana nezixhobo, ifake izixhobo zokusika, i-berer egqwesileyo yokumelana, i-bear-surgery, ukuxhathisa ukusika. kunye nezixhobo zevalve.Ngelixa ingeyokumelana ne-corrosion njenge-austenitic stainless steels (umzekelo, i-304, i-316), i-440C inika ukuxhathisa okulungileyo kokuhlwa kwiindawo ezipholileyo. Iyakwazi ukumelana nokugqwala kunezinye iintsimbi eziphezulu zekhabhoni ngenxa yomxholo we-chromium.I-440C insimbi engenasici inokuthi iphathwe ubushushu ukuze ifezekise izinto ezifunwayo zemishini.

Yintoni 440C Stainless Steel?
I-440C insimbi engenasici inika ibhalansi yokumelana nokunxiba kakuhle kunye nokunyanzeliswa kokuthotywa kwe-corrosion kwindawo epholileyo, enobunzima obukhulu. Yabelana ngokufana nebakala le-440B kodwa inomxholo wekhabhoni ephezulu, ekhokelela kubulukhuni obuphezulu kodwa iyancipha ukuxhathisa ukubola xa kuthelekiswa ne-440B. Inokufikelela kubulukhuni ukuya kutsho kuma-60 e-Rockwell HRC kwaye imelana nokuhlwa kwimekobume yemizi-mveliso yasekhaya eqhelekileyo, enokumelana neyona nto ifikelelekayo ngaphantsi kweqondo lobushushu elimalunga nama-400°C. Ukulungiswa komphezulu kubaluleke kakhulu ukuze kuxhathiswe umhlwa, kufuneke kususwe isikali, izithambiso, amasuntswana angaphandle, kunye neengubo zokwaleka. Umxholo wayo ophezulu wekhabhoni uvumela ukucwangciswa kwemishini efana ne-annealed high-speed steel grade.
440C Stainless Steel Round Bar yokuFaka isicelo:
I-440C imivalo ejikelezayo yensimbi engenasici isetyenziswa ngokubanzi ekwenzeni imela, iibheringi, izixhobo kunye nezixhobo zokusika, izixhobo zonyango, amacandelo e-valve, kunye nezixhobo zoshishino, apho ubunzima babo obuphezulu, ukuxhathisa ukugqoka, kunye nokuxhatshazwa kwe-corrosion kubenza babe ukhetho olufanelekileyo kumacandelo abalulekileyo afuna ukusebenza okugqwesileyo kunye nokuqina kwexesha elide.
Ukuwelda kweNtsimbi engatyiwa 440C:
Ngenxa yokuqina kwayo okuphezulu kunye nokulula kokuqina komoya, i-welding ye-440C yensimbi engenasici ayiqhelekanga. Nangona kunjalo, ukuba i-welding iba yimfuneko, kuyacetyiswa ukuba uqalise ukutshisa izinto kwi-260 ° C (500 ° F) kwaye wenze unyango lwe-post-weld annealing kwi-732-760 ° C (1350-1400 ° F) kwiiyure ze-6, kulandelwa ukupholisa okucothayo kwesithando somlilo ukukhusela ukuqhekeka. Ukuqinisekisa iimpawu ezifanayo zomatshini kwi-weld njengesiseko setsimbi, i-welding consumables kunye nokubunjwa okufanayo kufuneka isetyenziswe. Kungenjalo, i-AWS E/ER309 inokuqwalaselwa njengokhetho olufanelekileyo.
