Cov khoom siv tshuaj ntawm Q235NH weathered steel phaj
Lub npe tag nrho ntawm Q235NH corten sheet yog atmospheric corrosion-resistant kub steel, tseem hu ua corten steel thiab corrosion-resistant steel. Q235NH corten steel ntawv yog dav siv nyob rau hauv: ntim, fais fab nroj tsuag chimneys, railway engineering thiab lwm yam sab nraum zoov hlau.
Q235NH weathering steel yog ua los ntawm cov pa roj carbon zoo tib yam nrog me me ntawm tooj liab, npib tsib xee thiab lwm yam corrosion- tiv taus cov ntsiab lus ntxiv. Nws muaj cov yam ntxwv ntawm siab- zoo steel xws li lub zog, yas txuas ntxiv, shaping, vuam thiab txiav, puas, kub kub, qaug zog, thiab lwm yam. Tsis tas li ntawd, Q235NH weathering steel ntawv huab cua tsis kam Nws yog 2 mus rau 8 npaug ntawm cov pa roj carbon zoo tib yam.
Q235NH corten daim ntawv muaj cov yam ntxwv ntawm xeb kuj, tiv thaiv - corrosion thiab lub neej txuas ntxiv ntawm cov khoom, thinning thiab noj txo, txuag zog thiab zog.
