SWCH6A rau SWCH22A Lub Taub Hau Txias Taub Hlau Hlau 2mm To42mm

 

SWCH6A yog cov pa roj carbon hlau xaim rau cov taub txias.

 

Kev tsim:

"S" {= steel

"W"=xaim hlau

"C" {{=} txias (txias-tsim)

"H" {{{= he} (rau cov txheej txheem txias)

"6" {{{{= cov ncauj lus pa roj carbon monoxide. {0. {}}. 08%)

"A" {{=} aluminium-tua steel (deoxidized nrog txhuas)

 

Tshuaj Muaj Tshuaj:

Cov pa roj carbon tsawg (0. {04-0. 08%).

Me alloy cov ntsiab lus: manganese (mn), leej faj (phosphorus (p), nrog txhuas (al) {}}. 02%.
