** 1. Plaub yam tshuaj carbon hlau yog dab tsi? **
Plaub hom ntawm cov roj carbon hlau loj, faib los ntawm lawv cov ntsiab lus carbon, yog:
* ** STUPON STEEL (hlau me): ** muaj txog 0.3% carbon. Nws yog daim foos thiab pheej yig tshaj plaws; Nws yog malastable, ductile, thiab yooj yim welded tab sis tsis tuaj yeem ua kom tawv tawv los ntawm kev kho cua sov.
* ** MENTERLOLOGY STEEL: ** muaj ntawm 0.3% thiab 0.6% carbon. Nws sib npaug thiab lub zog, thiab tuaj yeem ua cua sov {{}}} nrhiav kho kom nce nws lub hardness. Nws feem ntau siv rau cov khoom siv tsheb thiab cov tshuab ua haujlwm.
* ** High carbon hlau: ** muaj ntawm 0.6% thiab 1.0% carbon. Nws muaj zog heev, nyuaj, thiab tuaj yeem tuav lub ntsej muag ntse, tab sis nws tsawg dua coorile thiab ntau nkig. Nws yog feem ntau siv rau kev txiav cov cuab yeej, springs, thiab siab- lub zog kav hlau.
* ** HEEV cov hlau steel (tuam hlau): ** muaj ntawm 1.0% thiab 2.0% carbon. Nws yog ib qho tshwj xeeb nyuaj thiab nkig, thiab nws yuav luag tshwj xeeb rau cov ntawv thov tshwj xeeb xws li cov cuab yeej txiav txiav tej cov cuab yeej, punches, thiab tuag.
** 2. Qhov twg yog qhov zoo dua, muaj cov pa roj carbon lossis cov roj carbon steel? **
Tsis yog inherently "zoo dua"; kev xaiv yog nyob ntawm daim ntawv thov.
* ** Xaiv cov roj carbon chev me me ** Thaum koj xav tau cov khoom siv uas yooj yim rau cov duab, daim ntawv, thiab Weld. Nws yog qhov zoo tagnrho rau cov txheej txheem thav duab, lub cev tsheb lub cev, xaim, thiab cov ntawv hlau uas muaj zog tsis yog thawj qhov yuav tsum tau ua.
* ** Xaiv cov hlau roj carbon hlau ** Thaum koj xav tau lub hardness siab, hnav tsis kam, thiab muaj peev xwm tuav lub ntsej muag ntse. Nws yog qhov zoo dua rau kev ua riam, tawg, springs, thiab lwm yam cuab yeej uas muaj zog yog qhov tseem ceeb. Txawm li cas los xij, nws yog ntau nkig thiab tsis yooj yim ua haujlwm nrog.
** 3. Uas yog qhov zoo dua, SS lossis ms? **
"SS" (Stainless hlau) thiab "MS" (hom me me, hom qis carbon hlau) pab cov hom phiaj sib txawv, yog li ib qho tsis zoo dua.
* ** STANLESS STEEN (SS) ** yog ib qho alloy muaj tsawg kawg ntawm 10.5% chromium, uas muab nws zoo heev corrosion. Nws yog kim dua, nyuab rau lub tshuab, thiab yog siv qhov kev nyiam huv, thiab cov khoom siv ua haujlwm, cov khoom siv tshuaj kho cov khoom siv, cov khoom siv architectural).
* ** Cov hlau me me (MS) ** yog muaj zog ntau dua thiab nyuaj dua li cov hlau tsis muaj xeb (nws yuav xeb yooj yim tshwj tsis yog hais tias tsis yog xim). Nws yog qhov pheej yig dua, yooj yim rau weld thiab tshuab, thiab yog cov khoom siv rau kev tsim kho, txuas hniav, txua nkoj, thiab kev ua haujlwm.
** 4. Dab tsi yog qib siab tshaj plaws ntawm cov pa roj carbon hlau? **
Lo lus "qib siab tshaj plaws" tuaj yeem xa mus rau cov cim carbon lossis lub zog. Nyob rau hauv cov nqe lus ntawm cov ntsiab lus carbon, ** muaj cov hlau roj carbon monoxide heev ** (kuj tau faib ua ** cov hlau tsim 2%, yog qhov siab tshaj plaws. Ib qho piv txwv yog qib li ** 1095 **, uas yog siv dav rau riam. Nyob rau hauv cov nqe lus ntawm lub zog, ** ultra {{5 5}} cov pa roj carbon ntau, tuaj yeem ua kom zoo nkauj, tab sis nws yog siv rau cov ntawv thov tshwj xeeb.
** 5. Yog 304 ib tug siab carbon hlau? **
Tsis yog, ** 304 stainless hlau tsis yog ib qho siab carbon hlau **. Nws yog hom nquag heev ntawm ** Austenitic Stainless Hlau **. Nws cov yam ntxwv tseem ceeb yog nws zoo heev corrosion tsis kam, uas los ntawm nws cov chromium siab (18-20%) thiab npib tsib (8-10.5%) cov ntsiab lus. Nws cov ntsiab lus carbon yog tsawg heev (ntau tshaj plaws ntawm 0.08%), muab nws ua "cov pa roj av" cov roj av stainless hlau stainless. Cov ntsiab lus carbon tsawg no pab tiv thaiv kom corrosion sensitical thaum vuam.
