Classification ntawm steel kav

Muaj ntau txoj hauv kev los faib cov yeeb nkab steel, tab sis cov txheej txheem feem ntau yog raws li lawv cov yam ntxwv.Tom qab ntawd peb muaj 04 nrov steel yeeb nkab kev faib tawm: carbon steel yeeb nkab, stainless hlau yeeb nkab, dub steel yeeb nkab, thiab galvanized steel yeeb nkab.

Carbon steel yeeb nkab

Cov pa roj carbon steel yeeb nkab yog ua los ntawm cov hlau nrog cov pa roj carbon raws li cov tshuaj tseem ceeb thiab txiav txim siab txog qib ntawm lub cev muaj zog xws li lub zog thiab lub zog ntawm cov hlau, yog li carbon steel yeeb nkab yog suav tias yog cov khoom kim tshaj plaws ntawm cov yeeb nkab steel.Thaum lub sij hawm tsim cov txheej txheem, cov neeg tsim khoom ntxiv cov pa roj carbon monoxide rau cov hlau kom tawv thiab ntxiv dag zog rau cov khoom hlau.

Raws li daim ntawv thov, carbon steel yeeb nkab tau muab faib ua ultra-high carbon steel yeeb nkab, siab carbon steel yeeb nkab, nruab nrab carbon steel yeeb nkab, qis carbon steel yeeb nkab, thiab qis carbon steel yeeb nkab.

Cov kav dej carbon steel feem ntau yog siv los thauj dej thiab dej khib nyiab hauv av, hauv kev lag luam uas muaj qhov kub thiab txias…

Stainless steel yeeb nkab

Cov kav hlau stainless yog dav paub txog lawv qhov kev tiv thaiv corrosion ntau thiab yog qhov xav tau zoo hauv ntau lub tebchaws.Kuj tseem hu ua inox steel kav, lawv yog ua los ntawm cov hlau uas muaj hlau, carbon, thiab tsawg kawg yog 10.5% chromium cov ntsiab lus, ntawm cov chromium yog lub ntsiab tseem ceeb.Hauv cov kav hlau stainless, muaj txheej txheej passivation uas pab tiv thaiv cov hlau los ntawm kev puas tsuaj los ntawm cov tshuaj tiv thaiv ntawm chromium thiab oxygen.

Cov kav hlau stainless feem ntau siv hauv kev tsim kho, kev thauj mus los, thiab lwm yam kev lag luam, xws li kev lag luam tsheb, kev lag luam tshuaj ...

Btsis muaj steel yeeb nkab

Cov yeeb nkab dub yog qhov ruaj khov tshaj plaws steel yeeb nkab ntawm kev muag khoom vim nws yooj yim thiab ruaj khov.Cov yeeb nkab dub, tseem hu ua cov yeeb nkab steel hlau lossis cov yeeb nkab tsis muaj steel, yog ua los ntawm cov hlau tsis muaj txheej txheej.Cov "dub" hauv nws lub npe los ntawm cov hlau oxide tsaus nti uas ua rau ntawm nws qhov chaw thaum lub sijhawm tsim khoom.

Cov kav dej dub kuj tseem siv los thauj dej thiab roj thiab hauv kev tsim kho kev lag luam, tshwj xeeb tshaj yog rau kev ua laj kab thiab scaffolding.

Galvanized hlau

Galvanized steel kav yog ua los ntawm steel coated nrog ob peb txheej tiv thaiv ntawm molten zinc los tiv thaiv xeb thiab corrosion ntawm cov kav dej.Cov txheej txheem galvanizing tau tsim nyob rau xyoo 1950, thiab txij li ntawd los cov kav hlau galvanized tau hloov cov kav hlau lead.

Galvanized steel kav feem ntau yog siv los ua dej xa khoom thiab cov khoom siv hauv tsev, thiab tau siv dav hauv kev lag luam automation thiab engineering engineering, neeg caij tsheb lub cev, railway bogie manufacturing, thiab ntau lwm yam lag luam ...
