Hlau yog dab tsi?
Hlau yog ib qho alloy ntawm cov hlau thiab tus thawj xibfwb (lub ntsiab) sib hais yog carbon. Txawm li cas los xij, muaj qee qhov kev zam rau lub ntsiab lus no zoo li kev pub dawb-dawb (yog tias) hlau thiab hom 409 Ferritic stainless hlau, nyob rau hauv uas cov pa roj carbon tau suav tias yog impurity.
Dab tsi yog ib qho li cas?
Thaum cov khoom sib txawv tau sib xyaw ua ke hauv cov khoom me me hauv qhov pib, cov khoom lag luam uas tau hu ua alloy ntawm lub hauv paus keeb. Li qub steel yog ib qho alloy ntawm hlau vim tias hlau yog lub hauv paus ntsiab (tseem ceeb Ib co lwm yam khoom xws li manganese, silicon, npib chromium, titanium, thiab lwm yam tseem muaj ntxiv rau cov qib sib txawv los tsim cov qib sib txawv (lossis cov hom) ntawm cov hlau.
Jindalai (Shandong) Steel Group Co., Ltd. yog tus kws tshaj lij thiab ua tus xa khoom ntawm cov hlau thiab cov kav hlau / kav / cov hlau. Xa koj qhov kev nug thiab peb yuav zoo siab los sab laj koj tshaj lij.
Dab tsi yog qhov sib txawv ntawm cov hlau?
Raws li cov tshuaj lom neeg sib xyaw ua ke, cov hlau tuaj yeem raug faib ua plaub (04) hom pib:
Spry carbon hlau
● Stainless hlau
● Alloy Hlau
App Cuab Yeej Siv Hlau
1. Cov hlau ua hlau:
Cov hlau roj carbon hlau yog cov siv siv hluav taws xob feem ntau hauv kev lag luam thiab cov nyiaj rau ntau dua 90% ntawm cov steel ntau lawm. Raws li cov ntsiab lus carbon, cov hlau nplaum carbon hlau yog cov neeg coob ntxiv ua peb pawg.
● Cov me carbon hlau / cov hlau me
Istanbul Cov Hlau Steel
Insia Muaj pa roj carbon
Cov ntsiab lus carbon yog muab rau hauv cov lus hauv qab no:
| Tsis yog. | Hom carbon hlau | Feem pua ntawm carbon |
| 1 | Cov pa roj carbon hlau qis / hlau me | Mus txog 0.25% |
| 2 | Nruab Nrab Cov Hlau | 0.25% rau 0.60% |
| 3 | Cov Roj Hlau Siab | 0.60% mus rau 1.5% |
2. Stainless hlau:
Stainless hlau yog ib qho txheej txheem hlau alloy uas muaj 10.5% chromium (tsawg kawg). Stainless hlau nthuav tawm corrosion resistance cov yam ntxwv, vim yog tsim ntawm ib txheej nyias nyias ntawm cr2o3 ntawm nws nto. Cov txheej no tseem muaj lub npe hu ua txheej passive. Nce cov nyiaj ntawm chromium yuav ntxiv ntxiv rau cov corrosion tsis kam ntawm cov khoom siv. Ntxiv rau cov chromium, npib tsib xee thiab molybdenum kuj tseem ntxiv rau impart xav tau (lossis txhim kho) cov khoom. Stainless hlau kuj tseem muaj cov roj carbon ntau, silicon, thiab manganese.
Stainless hlau yog ntxiv cais li;
1. Ferritic stainless hlau
2. Martensitic Stainless hlau
3. Austenitic Stainless Hlau
4. Duplex Stainless hlau
5. Naithemation-hardening (PH) stainless hlau
● Ferritic stainless hlau: Ferritic steels: cov roj chromium alloys nrog lub cev-nruab nrab Crystal cov qauv (BCC). Cov no feem ntau yog sib nqus thiab tsis tuaj yeem ua kom tawv los ntawm kev kho cua sov tab sis tuaj yeem txhawb nqa los ntawm kev ua haujlwm txias.
●Thov Austenicial Stainless Hlau: Austenitic cov hlau yog feem ntau corrosion-resistant. Nws yog tsis muaj kev sib nqus thiab tsis sib nqus. Feem ntau, cov hlau tsis txaus ntseeg yog muaj kev sib luag heev.
Martensitic Stainless hlau: Martensitic Stainless hlau yog muaj zog heev thiab tawv tab sis tsis yog xeb-resistant li lwm ob chav kawm. Cov hlau no muaj cov tshuab nqus heev, sib nqus, thiab cua sov.
● Cov hlau stainless hlau: Duplex Stainless hlau muaj ob-theem micrivtructure muaj cov nplej ntawm cov hlau ferritic thiab austenitic stainless hlau (piv txwv li Ferrite + Austenite + Austenite) Austenite). Duplex cov hlau yog hais txog ob zaug kom muaj zog raws li Austenitic lossis Ferritic stainless hlau.
● Naikhaum-hardmentenation-hardivation (Ph) nag (daus) nag lossis daus
3. Alloy Steel
Hauv alloy steel, sib txawv sib piv ntawm cov ntsiab lus siv tau siv, txhim kho) cov khoom siv xws li weldability, thiab corrosity siv ntau yam thiab lawv cov teebmeem tau muaj raws li hauv qab no;
Manganese - Ua kom muaj zog thiab hardness, txo qis ductility thiab weldability.
Silicon - siv ua deoxidizers siv hauv cov steel ua.
● Phosphorus - ua kom muaj zog thiab hardness thiab txo qis dua thiab cov ntsiab lus cuam tshuam tawv ntawm cov hlau.
● Sulfur -Decreases ductility, notch cuam tshuam tus kheej, thiab weldability. Pom nyob rau hauv daim ntawv ntawm sulfide suav nrog.
● Tooj - txhim kho corrosion tsis kam.
● Cov npib tsib xee - nce cov khoom muaj zog thiab cuam tshuam lub zog ntawm cov hlau.
● Molybdenum - Ua kom muaj zog heev thiab txhim kho cov creep tsis kam ntawm cov hlau tsis muaj roj.
4. Cuab Yeej Siv Hlau
Cuab Yeej Cuab Yeej muaj cov ntsiab lus muaj roj carbon monoxide siab (0.5% mus rau 1.5%). Cov ntsiab lus carbon ntau dua muab cov hardness ntau dua thiab lub zog. Cov hlau no feem ntau siv los ua cov cuab yeej thiab tuag. Cuab Steel Steel muaj ntau ntau ntawm tungsten, colybdenum, thiab vanadium kom nce cov cua sov thiab hnav tsis kam, thiab kav ntev ntawm cov hlau. Qhov no ua rau cov cuab yeej siv hlau heev heev rau kev siv raws li kev txiav thiab drilling cov cuab yeej.
