Cov Khoom Taw Qhia thiab Siv
Austenitic Stainless Hlau Sus303 yog ib hom ntawm alloy txheej txheem hlau nrog kev txiav cov tshuab dhos zoo thiab ua cov machining zoo. Cov hauv qab no yog cov ncauj lus kom ntxaws ntawm sus303:
Kev txiav kev ua tau zoo kawg: Vim yog cov kev sib ntxiv ntawm cov leej txiv thiab phosphorus, kev txiav tawm ntawm sus303 tau tsim kho kom zoo dua qub thiab yog tsim nyog txhim kho ntawm qhov ntsuas ntsuas [.
Zoo corrosion Kuj: Txawm hais tias nws corrosion tsis yog tsis zoo li 304 lossis 316 stainless hlau, sus appstance rau atmospheric corrosion23.
High cua kub tiv: nws tuaj yeem tiv taus kub txog 870, ua rau nws haum rau cov ntawv thov kub siab2.
Cov neeg tsis muaj txiaj ntsig: Ntxiv ntawm cov leej txiv thiab phosphorus cuam tshuam rau nws Weldability
Sus303 yog qhov zoo tshaj plaws rau kev siv tshuab ceev xws li bolts thiab txiv ntoo, thiab qhov twg hlawv cov cai yuav tsum tau ua.
Dav siv hauv kev kho tsheb, aerospace, kho mob, thiab ua khoom siv khoom noj vim nws zoo heev machinity thiab zoo corrosion tsis kam2.

Kev Kho Cua Sov
Tshem tawm Sus303 hauv cov txheej txheem ntawm kev ua haujlwm txias, siv lwm txoj kev ntxhov siab sab hauv thiab tawg, thaum txhim kho cov khoom siv sib luag ntawm cov khoom siv thiab kev ntxhov siab corrosion.
Cua kub kub: Feem ntau ntawm 450 - 850 degree. Yog tias qhov ntsuas kub tsawg dhau, nws nyuaj rau tshem tawm sab hauv kev ntxhov siab zoo rau kev sib cav zoo; Yog tias qhov ntsuas kub siab dhau lawm, nws yuav ua rau hloov pauv hauv cov khoom siv khoom, xws li hardness txo. Rau sus303 tom qab ua haujlwm txias, feem ntau xaiv qhov kub tsawg, xws li 450 - 650 degree; Rau welded seem, raws li cov txheej txheem vuam thiab cov tuab ntawm cov khoom siv thiab lwm yam kub, xaiv qhov ntsuas kub ntawm650 - 850 degree.
Lub Sijhawm Tuav: Feem ntau 1 - 3 teev. Rau qhov loj me lossis loj dua sab hauv kev ntxhov siab ntawm lub workpiece, tej zaum yuav tsum tau txuas lub sijhawm tuav.
Cov txheej txheem cua txias: Feem ntau, cua txias nrog lub cub tawg lossis qeeb cua txias hauv huab cua yog saws. Kev kub siab txias tuaj yeem ua rau sab hauv kev cuam tshuam ntawm cov khoom yog tso tawm tag nrho, tsis txhob muaj ntau tiam kev ntxhov siab tshiab thaum lub sijhawm ua kom txias.
Nyob rau hauv kev kho cua sov ntawm sus303, nws kuj yog qhov tsim nyog los them sai sai rau cov teeb meem nram qab no:
Yuav tsum ntxuav workpiece: ua ntej kev kho cua sov, qhov chaw ua haujlwm kom tshem tawm oxidation, etcien, decarburization thiab lwm yam tsis xws luag hauv cov txheej txheem kev kub ntxhov.
Cov cua sov ceev: rau cov haujlwm ua haujlwm ntawm qhov loj me lossis cov duab cua kub, lub cua sov yuav tsum tau tswj kom tsis txhob muaj kev cuam tshuam los yog tawg ntawm kev ntxhov siab ntau dhau ntawm kev ntxhov siab.
Cua txias zoo: nyob rau hauv tus txheej txheem txias ntawm kev kho, kom zam dhau qhov ua haujlwm txias nrawm dhau, yog li tsis tau tsim cov koomhaum tsis sib xws thiab tsis muaj kev ntxhov siab tsis sib xws thiab kev ntxhov siab sab hauv.
Cov khoom siv cua sov sov: xaiv txiav cov khoom siv kub kho kub, xws li muaj cua sov kub, thiab tswj cov khoom kom ntseeg tau qhov tseeb thiab ntsuas cua sov ntawm cov cua sov.
