I. Lub tswv yim
Q355GNH weathering steel (tseem hu ua atmospheric corrosion{1}}resistant steel) yog qib qis- alloy steel ntawm cov hlau zoo tib yam thiab stainless hlau. Los ntawm kev ntxiv me me ntawm corrosion-cov khoom tiv taus (xws li Cu, Ni), nws khaws cov khoom zoo ntawm siab- zoo steel-xws li lub zog, ductility, formability, weldability, cuttability, hnav tsis kam, siab -kub tsis kam, thiab qaug zog tiv thaiv- thaum tseem ceeb heev txhim kho huab cua tsis kam thiab corrosion kuj.

IV. Cov yam ntxwv tseem ceeb
Siab zog: Boasts siab yield thiab tensile lub zog, ua tau raws li qhov yuav tsum tau ntawm ntau yam engineering lug.
Zoo heev Corrosion Resistance: Lub ntuj xeb txheej (nto patina) zoo tiv thaiv corrosion los ntawm ya raws, oxygen, thiab tshuaj nyob rau hauv cov huab cua, ho txhim kho cov qauv durability.
Weldability zoo: Yooj yim rau vuam nrog ruaj khov thiab txhim khu kev qha zoo.
Environmental Friendliness: Siv eco-coatings tus phooj ywg thaum lub sij hawm tsim khoom, txo cov pa phem ib puag ncig.
Aesthetic Appeal: Features ib tug niaj hnub nto patina nrog ib tug txaus nyiam xim, muab zoo zoo nkauj teebmeem (rau tshwj xeeb kho steel daim hlau).
V. Daim Ntawv Thov Scope
Q355GNH tau dav nyiam rau nws cov khoom tshwj xeeb, nrog rau cov ntawv thov suav nrog:
Bridge Engineering: Siv los ua cov khoom siv tseem ceeb rau kev txuas hniav, tiv taus cua thiab nag yaig kom ntev kev pab cuam lub neej.
Kev tsim kho engineering: Siv rau hauv lub ru tsev, phab ntsa, thiab cov plag tsev kom txhim khu lub tsev durability thiab kev nyab xeeb.
Kev tsim tsheb: Txhim kho corrosion kuj nyob rau hauv tsheb, tsheb ciav hlau, thiab lwm yam tsheb.
Ntim Cov Khoom Siv: Ua ke zoo xeb kuj thiab lub zog siab kom muaj kev nyab xeeb kev thauj mus los.
Lwm yam teb: Petrochemical, fais fab, thiab kev tiv thaiv ib puag ncig kev lag luam; tsheb ciav hlau, chaw nres nkoj tsev, roj platforms; thiab cov khoom siv rau cov khoom siv tshuaj lom neeg / roj av (xws li, ntim rau hydrogen sulfide-corrosive media).
