Corten A hlau

Corten A Weathering Steel
ASTM Corten A steel qib yog cov khoom kub dov ntawm cov qauv hlau hauv cov txheej txheem kev xa khoom nrog kev txhim kho atmospheric corrosion resistance.The steel qib CortenA yog raws li ASTM tus qauv uas nrog lub zog ntawm 355MPa thiab lub zog tensile ntawm 470-630MPa.Corten- Ib lub hlau yog thawj zaug siv hauv tsev hauv xyoo 1958 vim nws muaj cov khoom tiv thaiv corrosion. Tom qab ntawd Corten-A tshwj xeeb tshaj yog nyob rau hauv Suav teb thiab Nyij Pooj tau siv dav rau kev txuas hniav, tsheb ciav hlau, tsheb, tsheb thauj khoom thiab chaw tsim khoom thiab lwm yam.

Cov txheej txheem saum toj kawg nkaus ntawm cov khoom siv ua haujlwm nrog cov ntsiab lus atmospheric los tsim cov xeb xim tiv thaiv txheej uas tsis yog tsuas yog ua rau cov hlau tsis muaj kev saib xyuas dawb xwb tab sis kuj muab qhov zoo nkauj thiab zoo ib yam.
