Dab tsi yog qhov txawv ntawm Mild Steel thiab Stainless Steel?
Stainless hlau:
Stainless acid-resistant steel yog hu ua stainless hlau. Nws yog tsim los ntawm ob ntu: stainless hlau thiab acid-resistant steel. Hauv luv luv, hlau uas tuaj yeem tiv taus atmospheric corrosion yog hu ua stainless hlau, thiab hlau uas tuaj yeem tiv taus tshuaj lom neeg corrosion yog hu ua acid-resistant steel. Feem ntau hais lus, hlau nrog cov ntsiab lus ntawm Wcr ntau dua 12 feem pua muaj cov yam ntxwv ntawm stainless hlau. Raws li lub microstructure tom qab kev kho cua sov, stainless hlau yuav muab faib ua tsib pawg: ferritic stainless hlau, martensitic stainless hlau, austenitic stainless hlau, Austenitic-ferritic stainless hlau, thiab precipitated carbide stainless hlau ntawv.
Stainless hlau feem ntau muab faib ua:
1. Ferritic stainless hlau. Muaj 12% mus rau 30% chromium. Nws cov corrosion kuj, toughness, thiab weldability nce nrog nce ntawm chromium cov ntsiab lus, thiab nws tsis kam mus rau chloride kev nyuaj siab corrosion yog zoo dua li lwm hom stainless hlau.
2, austenitic stainless hlau. Cov ntsiab lus chromium yog ntau tshaj 18 feem pua, thiab nws kuj muaj li ntawm 8 feem pua nickel thiab ib qho me me ntawm molybdenum, titanium, nitrogen, thiab lwm yam. Kev ua haujlwm zoo, tiv taus corrosion los ntawm ntau yam xov xwm.
3. Austenitic-ferritic duplex stainless hlau. Nws muaj qhov zoo ntawm austenitic thiab ferritic stainless hlau thiab muaj superplasticity.
4. Martensitic stainless hlau. Siab zog, tab sis tsis zoo plasticity thiab weldability.
Carbon steel:
Cov khoom tseem ceeb yog nyob ntawm cov ntsiab lus carbon hauv cov hlau, thiab feem ntau tsis ntxiv ntau cov ntsiab lus alloying rau cov hlau, qee zaum kuj hu ua cov pa roj carbon zoo tib yam lossis carbon hlau.
1.Carbon steel tseem hu ua carbon steel, uas yog hais txog cov hlau-carbon alloy nrog cov ntsiab lus carbon tsawg dua 2 feem pua WC.
2.Carbon steel feem ntau muaj me me ntawm silicon, manganese, sulfur, thiab phosphorus ntxiv rau carbon.
3.Carbon steel tuaj yeem muab faib ua peb pawg: carbon structural steel, carbon tool steel, thiab dawb-txiav cov qauv hlau raws li nws lub hom phiaj. Carbon structural steel tau muab faib ua ob hom: architectural structural steel thiab tshuab tsim cov qauv hlau;
4.Raws li txoj kev smelting, nws muaj peev xwm muab faib ua open-hearth steel, converter steel thiab hluav taws xob rauv hlau;
5. Raws li txoj kev deoxidation, nws tuaj yeem muab faib ua boiling steel (F), tua steel (Z), semi-tua steel (b) thiab tshwj xeeb tua steel (TZ);
6.According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%—0.6%) and high carbon steel (WC>0.6 feem pua );
Raws li cov ntsiab lus phosphorus thiab sulfur, carbon hlau tuaj yeem muab faib ua cov pa roj carbon zoo tib yam (siab dua phosphorus thiab sulfur), cov pa roj carbon zoo (tsawg phosphorus thiab sulfur), thiab cov hlau zoo siab (qis phosphorus thiab sulfur). Super zoo steel.
Feem ntau cov pa roj carbon steel, qhov siab dua cov ntsiab lus carbon, qhov hardness ntau dua thiab siab dua lub zog, tab sis cov yas qis dua.
Q235 thiab Q195 feem ntau yog siv cov pa roj carbon steel, thiab Lawv tsis zoo ib yam.
Q195 yog cov khoom siv carbon steel. Lub zog tawm los yog 195MPA. Lub zog qis dua Q235. Tus nqi pheej yig dua. Siv nyob rau hauv kev tsim kho, qauv, maus taus thav duab, thiab lwm yam. Feem ntau tsis siv rau cov khoom siv.
Q235 tseem hu ua cov qauv carbon zoo tib yam. Q sawv cev rau qhov txwv tsis pub dhau ntawm cov khoom siv no, tom kawg 235 yog hais txog tus nqi tawm los ntawm cov khoom siv no, thiab lub zog tawm los ntawm Q235 yog txog 235MPa. Thiab nrog qhov nce ntawm cov thickness ntawm cov khoom, tus nqi tawm los yuav txo. Vim muaj cov ntsiab lus ntawm cov pa roj carbon monoxide, qhov kev ua tau zoo tag nrho yog qhov zoo dua, lub zog, plasticity, thiab vuam cov khoom zoo sib xws, thiab kev siv yog qhov dav tshaj plaws. Feem ntau siv rau hauv cov khoom siv.
HML produces hlau ntim,roll cages, kev ruaj ntseg, steel stacking racks, thiab lwm yam khoom raws li raw khoom siv Mild steel Q235, feem ntau vim hais tias cov khoom ntawm Mild steel Q235 muaj plasticity, zoo toughness, tsis kam rau vuam tawg, thiab zoo heev vuam kev ua tau zoo. HML qhov no Pab cov neeg siv khoom zoo tshaj plaws thiab tus nqi zoo tshaj.
Yog tias koj xav tau cov lus hais lossis kev txhawj xeeb txog peb cov khoom siv hlau, xa peb ib kab hnub no. Qhia peb me ntsis txog koj tus kheej thiab koj cov kev xav tau, thiab ib tus ntawm peb cov kws tshaj lij yuav hu rau koj sai sai los tham txog cov kev daws teeb meem uas peb tuaj yeem muab tau!
