GB/T 4171 Q235NH Huab cua Resistant Steel Sheets
Q295NH corten steel sheet hlau, "Q" sawv cev rau tsab ntawv ntawm yielding pinyin, "235" sawv cev rau lub zog ntawm 235MPa, "NH" yog tsab ntawv ntawm huab cua pinyin.
Q295NH weathering-resistant structural steel, xa hauv kub dov, normalized thiab normalized thiab tempered mob, muaj cov yam ntxwv ntawm siab- zoo steel, xws li toughness, yas ductility, molding, vuam, puas, kub thiab lwm yam.

Q235NH weathered steel phaj cov ntsiab lus
Q235NH corten daim ntawv xa tuaj: kub dov, tswj dov, normalized, thiab lwm yam.
Q235NH weathering steel sheets Executive Standard: GB/T4171-2008.
Q235NH weathering steel phaj Smelting Method: Hlau yog smelted los ntawm converter los yog hluav taws xob rauv, thiab nws yog sedated hlau.
Kub dov hlau yog xa hauv kub dov, tswj dov los yog normalized mob, Q235NH tuaj yeem xa tuaj rau hauv quenched thiab tempered mob, txias dov hlau feem ntau xa nyob rau hauv annealed mob.
Q235NH weathering phaj yog dav siv nyob rau hauv: ntim, fais fab nroj tsuag, chimneys, railway engineering thiab lwm yam sab nraum zoov hlau, xws li loj sab nraum zoov sculpture steel, weathering steel (ie, atmospheric corrosion- resistant steel) yog nruab nrab ntawm cov hlau zoo tib yam thiab stainless hlau uas tsis muaj alloy steel series ntawm tus nqi qis thiab zoo zoo.
Cov yam ntxwv ntawm Q235NH weathering steel
1. Rust-resistant, corrosion-resistant, nrog 4-8 npaug siab atmospheric corrosion kuj dua li cov hlau dav dav;
2. Cov khoom siv tuaj yeem rov ua dua thiab siv tau, cov pa roj carbon tsawg heev thiab kev tiv thaiv ib puag ncig;
3. Corrosion-resistant steel lub neej txuas ntxiv, thinning thiab noj txo, txuag zog thiab txuag hluav taws xob;
4. Ntsuab, tsis muaj thawj painting; tuaj yeem txo qhov kev siv cov xim tsis muaj hluav taws kub thiab hluav taws kub, yog li txo cov pa phem, ua kom lub sijhawm luv, txo cov nqi thiab txo kev txij nkawm, yog ib hom "ntsuab", kev txhim kho kev lag luam ntawm cov hlau.
