Q355NH yog corten steel phaj, thiab Q355GNH yog corten steel phaj. Lawv ob leeg nyob rau hauv qis-alloy series thiab yog xeb-resistant. Lawv tuaj yeem tiv taus corrosion thiab ncua lub neej ntawm cov khoom, txo cov tuab thiab txo kev noj, thiab txuag kev ua haujlwm thiab lub zog.
Hais txog kev ua tau zoo thiab tus nqi, Q355GNH muaj kev ua tau zoo thiab cov khoom xyaw zoo dua li Q355NH, thiab tus nqi kuj siab dua.
Corten steel phaj feem ntau yog siv los tsim cov khoom siv xws li tsheb ciav hlau, cov tsev hauv hiav txwv, cov thawv ntim khoom, cov chaw tsim roj, cov khoom siv tshuaj thiab roj av, thiab cov thawv ntim uas muaj hydrogen sulfide corrosive media hauv cov roj derricks. Nws tseem tuaj yeem siv los tsim cov qauv hlau xws li cov pej thuam, kev tsheb ciav hlau, txuas hniav, tsheb, thiab lwm yam uas raug rau cov huab cua ntev.
