cov khoom siv thev naus laus zis
Weathering steel phaj kuj feem ntau hu ua weathering steel daim hlau vim lawv tsis kam rau atmospheric corrosion thiab huab cua. Cov huab cua ntawm cov hlau no yog dov nrog tooj liab, thaum txwv cov phosphorus thiab sulfur cov ntsiab lus kom cov nplaim tuaj yeem tiv taus huab cua thiab tsim cov txheej txheem tiv thaiv. Peb cov hlau phaj huab cua yog siv rau hauv cov txuas txuas txuas, cov tsev siab siab thiab cov thawv ntim khoom, nrog rau lwm cov qauv hlau sab nraum zoov siv nyob rau hauv ib puag ncig hnyav.
Cov kev cai thiab kev pabcuam ntxiv rau SMA490AW steel ntawv:
♦ Kev ntsuas qhov ntsuas kub tsawg
♦ Txiav thiab vuam raws li cov neeg siv khoom kawg
♦ Cov kev cai nruj dua rau qee yam tshuaj lom neeg
♦ Kev kuaj ultrasonic raws li EN 10160, ASTM A435, A577, A578
Thawj daim ntawv pov thawj zeb xeem raws li EN 10204 hom 3.1/3.2
Weathering steel, tseem hu ua weathering steel lossis atmospheric corrosion resistant steel, yog cov khoom siv zoo.
Weathering steels raug cais raws li "kev tiv thaiv tus kheej" steels vim tias lawv tsim "patina" vim oxidation ntawm qhov chaw tiv thaiv thaum raug huab cua; oxidized txheej muab cov hlau txawv txawv thiab txhim khu kev tiv thaiv huab cua piv rau cov qauv hlau, thaum kev txhim kho corrosion nyob rau tib lub sijhawm, kev txhim kho corrosion txuas ntxiv kev pab cuam lub neej.
Weathering steels feem ntau yog siv rau hauv kev tsheb ciav hlau, txuas hniav, dov Tshuag, ntim, vaj tsev thiab lwm yam kev siv.
