SMA400AW Weathering Steelmuab qhov zoo tshaj plawshuab cua tsis kam, tswj kev ua tau zoo nyob rau hauv ntau yam hnyav ntuj puag ncig lub sij hawm ntev. Txawm hais tias raug cua, los nag, lossis tshav ntuj hnyav, nws tseem nyob ruaj khov thiab corrosion-resistant. Qhov kev ua tau zoo tshaj no yog ua tiav los ntawmtshwj xeeb alloy muaj pes tsawg leegthiabadvanced manufacturing txheej txheem, kom ntseeg tau tshwj xeeb durability tiv thaiv qhov kev cov nyom.

 

SMA400AW steel phajyog ib hom kub dov atmospheric corrosion resisting hlau. SMA400AW steel tau ntxiv phosphorous uas ua rau cov khoom siv zoo tshaj plaws rau kev siv roj flue.

Kev xa khoom ntawm SMA 400AW weathering steel tuaj yeem raug cais raws li kub dov, txias dov, normalized, quenched, tempered, thiab thermo-mechanically tswj txheej txheem (TMCP).JIS SMA 400 AW weathering steel muaj ntau yam kev siv, thiab yog cov khoom zoo tshaj plaws rau kev tsim cov tsheb ua liaj ua teb wagons, cov kav dej, cov kav dej thiab cov kav dej. boilers.

 

Lub ntuj nto ntawm SMA 400 AW weathering steel feem ntau tsis tas yuav tsum muaj kev saib xyuas xws li kev pleev xim, uas ua rau cov khoom siv tus nqi - siv tau zoo rau lwm cov qauv hlau. Nws yog tsuas yog siv rau lub tank, ntim, txuas hniav, thav duab, tsheb thiab lwm yam kev tsim kho nrog vuam thiab bolting yuav tsum tau.

 

SMA400AW steel specifications: thickness 3mm ~ 200mm; dav 1000mm ~ 4100mm; Ntev 1000mm ~ 12000mm.
