1. Corrosion Resistance
Weathering hlau (Corten / A588 / Q355NH thiab lwm yam)Muaj alloying ntsiab xws liCu, Cr, Ni, P, uas tsim ib ntom, tiv thaivpatina txheejntawm qhov chaw.Corrosion npaum li cas2-8 zaug qeebdua li qub hlau; tuaj yeem siv tsis tau pleev xim rau sab nraum zoov ntev -.
Cov pa roj carbon zoo li qub (Q235, SS400, A36)Tsis muaj kev tiv thaiv alloy muaj pes tsawg leeg.Rusts sai thiab tsis tu ncua; xeb txheej yog xoob thiab ntxeem tau, cia noo noo nkag mus tob.
2. Nto xeb cwj pwm
Huab cua steelRusts pib, ces stabilizes mus rau hauv ib tug nruj, tsaus xim av patina thiab nres deepening.Yuav luag tsis muaj ntxiv corrosion tom qab cov txheej txheem tiv thaiv.
Cov hlau qubRusts tsis nres, maj mam ua thicker, flaky, thiab nws thiaj li ua raupitting thiab perforation.
3. Mechanical Properties
Huab cua steelHigh-lub zog low-alloy steel; feem ntausiab dua yield thiab tensile zogdua li cov hlau me me.zoo dua qaug zog thiab toughness nyob rau hauv atmospheric ib puag ncig.
Cov hlau qubTsawg zog; softer thiab ntau ductile nyob rau hauv cov qib theem pib.
4. Kev Pabcuam Lub Neej
Huab cua steelKev pabcuam lub neej sab nraum zoov tuaj yeem ncav cuagntau xyoo lawmthaum tsim nyog.
Cov hlau qubRusts los ntawm sab nraum zoov sai sai, feem ntau tsuas yog ob peb xyoos tsis muaj tha xim.
5. Txheej Txheej
Huab cua steelYuav siv tautsis pleev ximnyob rau hauv feem ntau atmospheric ib puag ncig.
Cov hlau qubYuav tsum tau pleev xim los yog galvanized; txwv tsis pub nws corrodes sai heev.
6. Tus nqi
Huab cua steelNtau kim dua vim alloying thiab ntau lawm txheej txheem.
Cov hlau qubTus nqi qis dua, dav dav raws li cov khoom siv dav dav.
7. Cov ntawv thov ib txwm
Huab cua steelTxuas hniav, ntim, tsev facades, sculptures sab nraum zoov, toj roob hauv pes tsim, kis tau tus yees.
Cov hlau qubKev tsim kho dav dav, cov khoom siv sab hauv, cov qauv ib ntus, qhov chaw tsis raug huab cua.
