{{01. Tsis muaj hlau stainless tawg nrog cua sov?
Kev ntxhov siab thermal tawg:
Kev hloov tam sim cua kub (thermal poob siab) tuaj yeem ua rau muaj kev cuam tshuam sai sai (ua rau cov kab nrib pleb
Austenitic steels (e {{{0} g}}}}}} {}}}, 430).
Nkag thiab qaug zog tawg:
Kev siv lub sijhawm ntev (saum cov hlau cov kev pom zoo tau txwv) tuaj yeem ua rau nkag (qeeb heev) thiab thaum ub tawg, tshwj xeeb tshaj yog nyob rau hauv cov tshuab kev ntxhov siab {}}
MARTENENITIC cov hlau (e {{{{0} g}}}}}}}}}}
Vuam cracks:
Thaum lub sij hawm vuam, cov cua kub hauv zos tuaj yeem ua rau cov khoom sib xyaw ua kom tawg yog tias muaj pes tsawg leeg tsis txaus lossis muaj cov niam txiv tsis txaus lossis muaj cov niam txiv tsis txaus ntseeg lossis muaj cov niam txiv tsis txaus ntseeg lossis muaj cov niam txiv uas tsis txaus ntseeg lossis muaj cov niam txiv uas tsis txaus ntseeg lossis muaj cov txiv leej ntoo
{{0 {}} Koj yuav ua li cas qib stainless hlau yog kub tiv taus?
Austenitic qib (ua yeeb yam tshaj tawm):
310s (25cr -20 ni): tsis kam mus txog ~ 1,292℃rau cov khoom cub thiab cua sov muaj cov khoom siv {}}
321 (18Cr -10 ni-ti-ti-} Ti): Ua kom muaj kev phom sij thiab hloov cua sov (1,652℃f) .
347 (18Cr -10 ni-ni-ni-ni-ni-ni-ni-ni-ni-ni-nb): li ~ 870℃f) .
Cov qhab nia ntawm Ferritic (kev tiv thaiv kab mob nrab):
430 (17Cr): Haum rau qhov kub txog rau ~ 800 Qib (1,472℃f), siv hauv qhov cub thiab automotive tso zis {}}
Tshwj xeeb alloys:
Incoloy 800 (45ni {-21 tus nickel alloy tab sis pab pawg ~ 1,112℃(2,112℃ib puag ncig {}
3. Yuav ua li cas paub yog tias stainless hlau yog rhuab?
Hloov xim: Oxidation ntawm cov kub sib txawv ua rau muaj cov xim sib txawv:
~ 200-300℃(392-572 Qib F): daj ntseg daj rau xim av .
~ 400-500℃(752-932 Qib F): Xiav rau ntshav .
~ 600-800℃(1,112-1,472 Qib F): ci xiav rau greyish nplai .
Saum toj no ~ 800 degree: tuab, flaky oxide txheej yuav ua .
Kev ntxhib phaj nto deg:
Cov cua sov kis tau tuaj yeem ua rau sib luam, pitting, lossis ntxhib, matte tiav (vs {} tus thawj du, ci saum npoo) {}.
Neeg kho tshuab hloov:
Hardness Testions (e {{{{0} g}}}}}, rockwell) yuav qhia tau ntau dua hauv Martensitic cov hlau yog tias overheated .
Microstructioning:

{{0 {}} Dab tsi yog qhov zoo tshaj plaws hom stainless hlau rau ua noj?
304 stainless hlau (18cr -8 ni):
Qhov kev xaiv tshwm sim tshaj plaws rau cookware vim nws txoj kev tiv thaiv corrosion zoo, durability, thiab pheej yig.
Muaj kev nyab xeeb rau cov khoom noj acidic (e {.}, txiv lws suav}, txog ~ 425 Qib F) .
Feem ntau siv nyob rau hauv pots, lauj kaub, thiab tais diav .
316 Stainless hlau (18Cr -10 ni -2 mo):
Ntxiv Molybdenum txhim kho kom pitting thiab crevice corrosion los ntawm ntsev lossis acidic cov khoom xyaw .
Nyiam rau high-end-kawg cookware lossis marine-cov cuab yeej ua noj chav ua noj ua noj, txawm tias me ntsis kim dua 304.
Clad Stainless Hlau (E . g .}}}}}}, tooj liab):
Composite tsim (stainless hlau sab nrauv nrog cov tub ntxhais ua haujlwm) txhim kho kev faib khoom kub, txo cov pob kub {}}
Qhov zoo tagnrho rau kev ua haujlwm-kev kawm ua cookware (e . pans lossis tsib-ply pans).
