GB / T Q235Nh Wighching Hlau Sawb Corrosion {} Nws muab cov khoom siv sib xyaw ua ke, ua rau muaj kev sib txuas nrog lub sijhawm tsawg kawg nkaus {}}

Q235NH tswj cov neeg paub kev ua tau zoo ntawm cov khoom siv roj carbon monoxide tab sis yog kev siv hluav taws xob tsawg dua rau nws cov kev lag luam me ntsis

 

 

 

Kev Ua Yeeb Yam

Atmospherric corrosion:
Los ntawm kev tswj hwm ntxiv ntawm cov ntsiab lus xws li Cu, C, Q235NTxoj kev sib zog nqus cov khoom siv tsis xeb, patina {1.

 

Lub zog nruab nrab, cov khoom ruaj khov:
Nrog rau cov txiaj ntsig zoo ib puag ncig ntawm 235 MPa, Q235NH muaj cov qauv kev ruaj khov thaum nws muaj kev ruaj khov rau cov txheej txheem thiab ua kom yooj yim rau cov txheej txheem thiab ua kom yooj yim rau cov txheej txheem thiab ua kom yooj yim rau cov txheej txheem thiab ua kom yooj yim rau cov txheej txheem thiab ua kom yooj yim rau cov txheej txheem thiab ua kom yooj yim rau cov txheej txheem thiab zawv.

 

Zoo heev Weldability thiab Formaty:
Q235NH yog paub rau nws cov yam ntxwv ua kom zoo - nws tuaj yeem tsim tau yooj yim, thiab tsim nws cov qauv txheej txheem kev sib sau ua ke rau modular thiab prefabricated muaj kev siv .

 

Kev daws teeb meem zoo:
Piv rau ntau dua-lub zog ua kom muaj zog ntawm cov txheej txheem Q460Gnh lossis Q235NH yog qhov kev txhawj xeeb uas tsis muaj txiaj ntsig thaum ua kom cov khoom siv thawj zaug tsawg {}}
