Raws li cov khoom siv raw rau SS cookware kov, qib 430 ferritic stainless hlau dominates nruab nrab-ntaucov khoom siv ua noj ua hausKev tsim khoom kom muaj tus nqi sib npaug thiab kev ua haujlwm zoo. Nws cov txiaj ntsig zoo suav nrog kev tiv taus kub siab kom tswj tau qhov kub ua noj luv luv txog li 450 ℃, tiv thaiv kev hloov pauv thermal thaum siv lub qhov cub. Tsis muaj cov khoom xyaw nickel kim, 430 txiav cov nqi khoom siv raw sai dua li 304 stainless hlau thiab muaj kev ruaj khov zoo rau kev tuav tes. Cov ntsiab lus chromium ntuj tsim cov zaj duab xis tiv thaiv xeb kom thaiv kev xeb hauv chav ua noj txhua hnub, phim cov kev cai tiv thaiv xeb yooj yim rau cov tes tuav lauj kaub.
Txawm li cas los xij, qhov tsis zoo uas muaj nyob hauv nws ua rau kev siv kim heev tsis zoo. Nws cov qauv ferritic ua rau pom tseeb tias muaj zog magnetism thiab tsis tiv taus corrosion tiv thaiv cov kua zaub ntsev thiab kua qaub ntev; kev tsau ntev ua rau cov xeb hauv zos yooj yim. Kev ua haujlwm kub tsis zoo ua rau muaj kev pheej hmoo ntawm kev tawg thaum muaj kev nias ntau dhau.
Nrov nto tiav rau SS cookware kov npogkev txhuam cov plaub hauthiabKev ua tiav iav 8Knrog rau kev lamination zaj duab xis tiv thaiv. Cov txheej txheem tsim khoom txheem muaj xws li kev txiav dawb paug, kev ntaus cim meej, kev tshem tawm ntug, kev ua kom kub siab, kev txhuam qhov chaw thiab kev qhwv zaj duab xis tiv thaiv zaum kawg. Cov teeb meem tsim khoom tseem ceeb tsom mus rau kev sib npaug ntawm kev txhuam kom sib xws: cov tes tuav ua noj nyias nyias feem ntau khoov thaum sib tsoo, thaum daim iav tiav xav tau ntau theem kev txhuam kom zoo kom tshem tawm cov khawb me me, ua rau cov khoom tiav qis dua. Kev tswj hwm qhov kub thiab txias nruj kuj tseem ceeb kom tiv thaiv kev hloov pauv ntawm kev ntxhov siab thermal hauv cov tes tuav uas tau tsim.
Tsom ntsoov rauSS cookware kovkev tsim khoom loj, AISI 430 ferritic stainless hlau coj ntau yam kev cuam tshuam kev ua tiav thoob plaws hauv kev tsim khoom.
Ua ntej, qhov tsis zoo ntawm qhov kub thiab txias hauv chav tsev ua rau tawg thaum lub sijhawm stamping thiab khoov. 430's ferritic crystal qauv tsis muaj nickel rau qhov tawv; cov tes tuav nyias nyias feem ntau tawg ntawm cov ces kaum nkhaus hauv qab txias, ua rau cov khoom seem nce ntxiv. Pre-annealing ntxiv cov nqi tsim khoom ntxiv los txhim kho plasticity.
Qhov thib ob, qhov ua kom tiav qhov chaw zoo ib yam yog qhov nyuaj rau kev kho cov plaub hau lossis daim iav. Qhov tawv ntawm cov khoom siv tsis sib xws ua rau muaj cov kab tsis sib xws. Cov tes tuav nyias nyias ua rau deform thaum muaj kev sib tsoo, ua rau daim iav 8K lossis txawm tias cov qauv plaub hau nyuaj rau ua tiav hauv cov khoom ntau.
Qhov thib peb, kev ntseeg tau ntawm kev vuam nrog cov khoom siv ua noj tseem nyuaj. Kev sib cais chromium ntau ntawm thaj chaw vuam ua rau chromium poob qis, ua rau tsis muaj zog tiv taus corrosion thiab yooj yim xeb nyob ib puag ncig cov pob qij txha tom qab siv chav ua noj ntev. Kub vuam ntau dhau kuj ua rau cov tes tuav tiav lawm puas.
Tsis tas li ntawd xwb, qhov tsis ruaj khov ntawm kev tiv thaiv xeb nyob rau hauv qhov chaw ua noj uas muaj av noo thiab kua qaub yog qhov tsis zoo uas zais cia. Zaj duab xis tsis muaj zog ntuj ntawm 430 tawg tawm tsam cov khoom noj ntsev, xav tau cov txheej txheem tiv thaiv nto ntxiv kom ua tau raws li cov qauv tiv thaiv xeb rau cov khoom siv ua noj.
