kev ua tau zoo
(1) Lub zog siab: feem ntau, nws lub zog tawm los yog siab dua 300MPa.
(2) High toughness: qhov yuav tsum tau elongation yog 15% ~ 20%, thiab qhov cuam tshuam toughness ntawm chav tsev kub yog ntau tshaj 600kJ / m ~ 800kJ / m.Rau loj welded Cheebtsam, siab dua tawg toughness kuj yuav tsum tau.
(3) Kev ua haujlwm vuam zoo thiab kev ua haujlwm txias.
(4) Tsawg txias brittle hloov kub.
(5) Zoo corrosion kuj.
3. Cov yam ntxwv ntawm cov yeeb nkab galvanized
(1) Cov pa roj carbon tsawg: vim qhov yuav tsum tau ua kom muaj zog, weldability thiab txias ua haujlwm, cov ntsiab lus carbon yuav tsum tsis pub tshaj 0.20%.
(2) Manganese raws li hlau alloy yog ntxiv.
(3) Ntxiv niobium, titanium los yog vanadium: ib qho me me ntawm niobium, titanium los yog vanadium ua cov carbide zoo los yog carbonitride hauv cov hlau, uas yog qhov tsim nyog kom tau txais cov khoom zoo ferrite thiab txhim kho lub zog thiab tawv ntawm cov hlau.Tsis tas li ntawd, ntxiv ib qho me me ntawm tooj liab (≤ 0.4%) thiab phosphorus (li 0.1%) tuaj yeem txhim kho corrosion kuj.Ntxiv ib qho me me ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb tuaj yeem tshem tawm cov sulfur thiab roj, purify steel, thiab txhim kho toughness thiab txheej txheem kev ua tau zoo.
