4 Hom Hlau

Cov hlau raug muab faib ua plaub pawg: Cov hlau carbon, Cov hlau sib xyaw, Cov hlau tsis xeb

Hom 1-Cov hlau carbon

Sib nrug ntawm cov pa roj carbon thiab hlau, cov hlau carbon tsuas muaj cov khoom me me xwb. Cov hlau carbon yog cov feem ntau ntawm plaub qib hlau, suav txog 90% ntawm tag nrho cov hlau tsim tawm! Cov hlau carbon tau muab faib ua peb pawg me raws li qhov ntau ntawm cov pa roj carbon hauv cov hlau:

Cov hlau carbon tsawg/cov hlau me me (txog li 0.3% carbon)

l Cov hlau carbon nruab nrab (0.3–0.6% carbon)

l Cov hlau carbon siab (ntau dua 0.6% carbon)

Cov tuam txhab feem ntau tsim cov hlau no ntau heev vim tias lawv pheej yig thiab muaj zog txaus siv rau hauv kev tsim kho loj.

 

Hom 2-Cov hlau sib xyaw

Cov hlau sib xyaw yog ua los ntawm kev sib xyaw cov hlau nrog cov khoom sib xyaw ntxiv xws li nickel, tooj liab, chromium thiab/lossis txhuas. Kev sib xyaw cov ntsiab lus no ua rau lub zog, kev ywj pheej, kev tiv thaiv xeb thiab kev siv tshuab ntawm cov hlau.

 

Hom 3-Cov hlau tsis xeb

Cov hlau tsis xeb yog cov hlau sib xyaw nrog 10–20% chromium nrog rau nickel, silicon, manganese, thiab carbon. Vim lawv muaj peev xwm ntau dua los tiv taus huab cua phem, cov hlau no muaj kev tiv thaiv corrosion siab heev thiab muaj kev nyab xeeb siv rau hauv kev tsim kho sab nraum zoov. Cov hlau tsis xeb kuj tseem siv dav hauv cov khoom siv hluav taws xob.

Piv txwv li, 304 stainless hlau yog dav nrhiav tom qab vim nws muaj peev xwm tiv taus ib puag ncig thaum khaws cov khoom siv hluav taws xob kom muaj kev nyab xeeb.

Txawm hais tias cov hlau tsis xeb sib txawv, suav nrog 304 stainless hlau, muaj qhov chaw hauv cov tsev, tab sis feem ntau nrhiav cov hlau tsis xeb vim nws cov khoom siv huv. Cov hlau no pom dav hauv cov khoom siv kho mob, cov kav dej, cov hlab siab, cov cuab yeej txiav thiab cov tshuab ua zaub mov.

 

Hom 4-Cov hlau siv ua haujlwm

Cov hlau siv rau cov cuab yeej, raws li lub npe qhia, zoo heev rau kev txiav thiab khawb cov khoom siv. Qhov muaj cov tungsten, molybdenum, cobalt thiab vanadium pab txhim kho kev tiv taus cua sov thiab kev ruaj khov dav dav. Thiab vim tias lawv tuav lawv cov duab txawm tias siv ntau dhau, lawv yog cov khoom siv nyiam rau feem ntau cov cuab yeej siv tes.

 

Kev faib tawm hlau

Dhau li ntawm plaub pawg, hlau kuj tseem tuaj yeem raug faib ua pawg raws li ntau yam sib txawv xws li:

Cov khoom siv: carbon, hlau, stainless hlau, thiab lwm yam.

Txoj kev xaus: kub dov, txias dov, txias tiav, thiab lwm yam.

Txoj kev tsim khoom: hluav taws xob cua sov, kev sib txuas tas mus li, thiab lwm yam.

Microstructure: ferritic, pearlitic, martensitic, thiab lwm yam.

Lub zog ntawm lub cev: raws li cov qauv ASTM

Cov txheej txheem de-oxidation: tua los yog semi-tua

Kev kho cua sov: annealed, tempered, thiab lwm yam.

Cov npe zoo: kev lag luam zoo, lub thawv siab zoo, kev kos duab zoo, thiab lwm yam.

 

Qib zoo tshaj plaws ntawm cov hlau yog dab tsi?

Tsis muaj qib hlau "zoo tshaj plaws" thoob ntiaj teb, vim tias qib hlau zoo tshaj plaws rau kev siv nyob ntawm ntau yam, xws li kev siv, kev xav tau ntawm lub cev thiab lub cev, thiab kev txwv nyiaj txiag.

Cov qib hlau uas siv tas li thiab suav tias yog cov koob saum toj kawg nkaus ntawm txhua hom suav nrog:

Cov hlau carbon: A36, A529, A572, 1020, 1045, thiab 4130

Cov hlau sib xyaw: 4140, 4150, 4340, 9310, thiab 52100

Cov hlau tsis xeb: 304, 316, 410, thiab 420

Cov hlau siv ua haujlwm: D2, H13, thiab M2

 

JINDALAI yog pawg hlau ua thawj coj uas tuaj yeem muab txhua qib hlau hauv coil, sheet, pipe, tube, rod, bar, flanges, elbows, tees, thiab lwm yam. Muab kev ntseeg siab rau Jindalai, thiab koj yuav txaus siab rau cov khoom.
