Taug txoj kev ntsia hlauYuav tsum tau tawm ntawm cov khoom siv hluav taws xob ntau zaus, cov khoom siv hnyav thiab kev xaiv ntawm cov khoom siv thiab kev nyab xeeb} cov ntaub ntawv tseem ceeb muaj:
1. Carbon Steel (xws li Q235, 45 # STEEL)
- NTA: Tus nqi qis, lub zog nruab nrab (tensile lub zog ntau dua los yog sib npaug rau 400MPA), dav siv rau kev taug qab zoo tib yam.
- Qhov kev txwv: yooj yim rau xeb, galvanized lossis blackened (lub thickness txheej yog feem ntau {μm, xa mus rau GB / t} .
2. Cov hlau stainless (xws li 304, 316)
- NTA: muaj zog corrosion resistance (316 stainless hlau tsuag tsuag dej txau> 500 teev, hais txog cov tshuaj tua kab mob as7).
- Qhov kev txwv: qis dua lub zog dua li alloy hlau (304 stainless hlau tensile lub zog ntau dua los yog sib luag rau 515MPA), nqi siab dua {3} {3}
3. Alloy Hlau (xws li 40CR, 35CRMO)
- NTA: lub zog siab (lub zog muaj zog ntawm 40cr tom qab quenching thiab xis nyob ntau dua lossis muaj kev sib npaug nrog cov tsheb ciav hlau thiab hnyav-thauj khoom.
- Kev txwv: kev kho cua sov (quenching + tempering) yuav tsum txhim kho kev ua tau zoo, thiab tus nqi ua yog siab.
