Kev ua tau zoo ntawm Q355NH atmospheric resistant steel phaj
Q355NH weathering steel yog lub npe tag nrho ntawm atmospheric corrosion resistant kub dov steel phaj, tseem hu ua corten steel thiab corrosion-resistant steel. Nws yog ib tug low-alloy series weathering steel. Cov "Q" ntawm Q355NH corten steel cov khoom sawv cev rau thawj tsab ntawv ntawm lo lus "Q" rau lub zog tawm los, "355" txhais tau tias nws lub zog tawm los yog 355MPa, thiab "NH" yog thawj tsab ntawv ntawm tus pinyin.
Nta ntawm Q355NH corten hlau ntawv:
Corrosion kuj: Q355NH atmospheric steel muaj zoo heev atmospheric corrosion kuj thiab muaj peev xwm tswj tau zoo stability rau lub sij hawm ntev nyob rau hauv ib puag ncig sab nraum zoov.
Lub zog thiab toughness: Q355NH corten weathering steel muaj lub zog, yas txuas ntxiv, thiab formability ntawm cov hlau zoo, thiab yog tsim rau ntau yam qauv thiab cov khoom siv kho tshuab.
Kev lag luam: Vim nws cov xeb tsis kam, cov khoom siv muaj cov yam ntxwv ntawm kev tiv thaiv corrosion thiab lub neej txuas ntxiv, thinning thiab noj txo qis, kev txuag hluav taws xob thiab txuag hluav taws xob, thiab lwm yam. Q355NH corten steel yog kev lag luam zoo heev los siv nyob rau hauv ib puag ncig hnyav.
