Kev faib tawm cov phiaj hlau

Cov phiaj hlau yog ib hom ntawm tiaj tus steel dav siv hauv kev lag luam ntau lawm thiab kev tsim kho. Lawv tuaj yeem raug cais ntau txoj hauv kev, feem ntau yog raws cov tuab, txheej txheem ntau lawm, cov yam ntxwv saum toj thiab siv. Cov hauv qab no yog cov ncauj lus kom ntxaws ntawm kev faib tawm ntawm cov hlau hlau:
1. Kev faib tawm los ntawm tuab
Daim nyias nyias hlau: qhov tuab tuab tsis tshaj 4 hli, thiab feem ntau siv hauv kev tsim cov tsheb tsim, aerospace thiab lwm thaj teb.
Nruab Nrab Daim Hlau: cov tuab yog nyob nruab nrab ntawm 4 thiab 20 hli, haum rau tsev qauv qauv thiab cov khoom siv kho tshuab.
Cov paib tuab: cov tuab tuab yog nruab nrab ntawm 20 thiab 60 hli, feem ntau yog siv rau cov qauv hnyav xws li cov kab mob nkoj thiab txuas hniav.
Cov paib tuab ntxiv: cov tuab tuab tshaj 60 mm, tsuas yog siv rau cov khoom ntim siab thiab cov phiaj xwm tshwj xeeb.

2. Kev Sib Tw Los Ntawm Cov Qauv Ntau Lawm
Kub-Rolled steel daim hlau: dov ntawm qhov kub thiab txias, nrog oxide teev nyob rau saum npoo, qis hardness tab sis zoo ductility.
Txias-dov daim hlau: dov ntawm chav tsev kub, nrog ib tug du nto, siab hardness thiab tsis yooj yim rau deform.

3. Kev cais tawm los ntawm cov yam ntxwv saum npoo
Galvanized ntawv: suav nrog kub-dip galvanized galvanized ntawv, siv rau corrosion tiv thaiv, siv dav hauv kev tsim kho thiab hauv tsev.
Tinplate: Qhov saum npoo yog coated nrog hlau tin, nrog zoo weldability thiab corrosion tsis kam, feem ntau siv nyob rau hauv cov zaub mov ntim thiab khoom siv hluav taws xob.
Composite steel ntawv: tsim ntawm cov khoom sib txawv, xws li Stainless Hlau
Xim coated steel phaj: coated nrog organic txheej rau saum npoo, siab lub zog thiab cov xim ci, siv nyob rau hauv kev tsim kho thiab tsheb tsheb.

4. Kev faib tawm los ntawm kev siv
Choj Steel phaj: Siv rau kev tsim kho choj, xav kom siab zog thiab siab heev.
Boiler Steel Phaj: Siv Rau Boiler Raug Tshuab Kub Thiab Kub Kuj.
Lub tais Steel: siv rau lub nkoj nkoj, xav tau corrosion tsis kam thiab muaj zog siab.
Tsheb Hlau Hlau Phaj: Siv rau lub cev tsheb thiab qhov chaw, xav tau lub teeb yuag thiab lub zog siab.
Hluav Taws Xob Hlau Phaj (silicon steel ntawv): siv rau cov motors thiab transformers, nrog zoo electromagnetic cov khoom.

5. Lwm yam pawg
Alloy Steel phaj: muab faib ua cov hlau nplaum tsawg, cov ntsiab lus nruab nrab ntawm cov ntsiab lus alloy, haum rau cov ntsiab lus alloy thiab lub zog sib txawv.
Stainless hlau phaj: muab faib ua Austenite, martensite thiab dulex stainless hlau raws li lub koom haum tsis kam thiab muaj kev kub ntxhov.
Los ntawm cov kev faib tawm saum toj no, peb muaj peev xwm nkag siab ntau dua ntawm cov yam ntxwv ntawm cov hlau, thiab muab cov ntaub ntawv xaiv rau kev xaiv tiag tiag thiab xaiv cov engineering.
