Stainless hlau yog cov hlau tsis xeb hlau uas muaj Chromium, Nickel thiab lwm yam, xws li Ni, uas tuaj yeem sib xyaw nrog cov hlau tsis huv, ntxiv rau kev nyuaj los txheeb xyuas stainless hlau los ntawm lwm hom hlau. Koj puas pom tias cov hlau stainless tsis yooj yim los txheeb xyuas?
Cov tswv yim siv lub zog ua rau pom tseeb tuaj yeem txheeb xyuas cov qib peb: Cr stainless hlau (series 400), Cr-Ni stainless hlau (series 300) thiab Cr-Mn-N stainless hlau (series 200 ), tab sis nws tuaj yeem 0010010 # 39; t paub qhov txawv ntawm qib tshwj xeeb steel. Tus tsis paub txog qib steel, peb tuaj yeem ua raws li lub cev thiab tshuaj lom neeg ntawm cov hlau, nrog kev pab ntawm cov cuab yeej yooj yim los txiav txim siab tias nws yog stainless hlau thiab hom hlau stainless nws yog dab tsi. Ntawm no peb yuav qhia qee cov qauv qhia kev yooj yim rau koj:

1. Kev saib xyuas cov xim ntawm cov khoom tom qab xaiv cov txheej txheem
Feem ntau hais lus, cov xim ntawm stainless hlau tom qab pickling yuav hloov pauv ntawm qhov chaw:
Qeb ntawm hlau | Xim tom qab pickling | Xim ua ntej de |
Cr-Ni stainless hlau | Nyiaj dawb | Xim av-dawb |
Cr stainless hlau | Grey-dawb, ci iab | Tsaus xim av |
Cr-Mn-N stainless hlau | Nyiaj dawb | Dub |
2 Kuaj nrog tooj liab sulfate
tooj liab sulfate xeem ntau zaus tuaj nrog cov txiaj ntsig zoo. Dissolve txog 8 gram ntawm tooj liab sulfate nyob txog 500 ml dej. Dais qhov ntawd rau yam khoom koj ntsuam xyuas. Cov pa roj carbon steel hlau yuav tsum tso cov xim tooj liab tam sim thaum cov hlau yaj thiab cov tooj liab hloov nws. ; t qhia kev tawm tsam, lossis nws 0010010 # 39; ll muaj tsawg heev.
3 Xeem nrog Cov Hlau nplaum
Lub alloy tsim ntawm cov hlau loj yuav txiav txim siab yog tias nws yog qhov sib nqus los yog tsis sib nqus. Txawm hais tias cov hlau nplaum tuaj yeem sib txawv Cr stainless hlau thiab Cr-N stainless hlau, nws tsis tuaj yeem paub qhov txawv ntawm qib steel thiab qhob steel tus lej.316, 201, 202 yog tib qho hlau tsis muaj qhov zoo los ntawm cov hlau nplaum, Tab sis, 304 tuaj yeem dhau los ua hlau nplaum thaum ua haujlwm txias. Vim tias Cr stainless hlau tuaj yeem raug tsim kho hauv ib qho xwm txheej twg; Cr-Ni stainless hlau feem ntau nonmagnetic hauv annealing, thiab qee qhov yuav sib nqus tom qab txias; Cov xwm txheej muaj hlau nplaum ntawm Cr-Ni-N stainless hlau yog qhov nyuaj dua: qee qhov tsis yog hlau nplaum, qee qhov tsis muaj hlau nplaum, qee qhov tsis sib nqus thiab kab rov tav yog sib nqus. Siab siab manganese steel yog kiag li nonmagnetic. 0010010 nbsp;
0010010 nbsp;
Rau cov hom hlau tshwj xeeb, kev siv tswv yim dua ntxiv txhawm rau txhawm rau txheeb xyuas lawv ：
1 Txheeb xeem
Yog tias koj grind me ntsis ntawm qhov khoom ntawm lub sib tsoo lub cav thiab nws muab cov txim taws tawm, cov khoom no feem ntau ua los ntawm 300-series qib ntawm Cr stainless hlau. Yog tias nws cuam lub "ci" 0010010 nbsp; ntawm cov txim taws hnyav, ces nws yog tus siab manganese lossis Mn-N steel.
2 0010010 nbsp; Kev kuaj Acid 0010010 nbsp;
Tso ib qho poob ntawm muaj zog Nitric acid / Sulfuric acid rau ntawm qhov chaw steel, lossis cov hlau hauv cov kua qaub nyob rau hauv chav sov. Kev soj ntsuam cov kev hloov ntawm cov xim saum npoo ntawm cov khoom: Cov kev tawm tsam, ntsuab muaju thiab tsaus xim: 302, 304; Qeeb ntaus, ziab saum npoo tig xim av: 316.
