ASTM A588 CORTEN STEEL Phajyog hom huab cua - Cov hlau tiv taus -} almao (hsla) txheej txheem steel tsev neeg.
Cov khoom siv no muaj cov kev ua tau zoo hauv vuam, riveting, thiab bolted tsim kho, ua kom dav nyob rau hauv cov txheej txheem kev ua yeeb yam xws li welded choj uas txo qhov hnyav thiab txhim kho durability yog xav tau.
Thaum raug rau kev mob sab nraud, Astm A588 cov hlau ua ib qho kev tiv thaiv patina, tso cai rau nws siv rau hauv ntau daim ntawv thov tsis muaj cov xim.
Lub ASTM A588 kev qhia tshwj xeeb muaj plaub qib: A588 qib A, qib B, qib C, thiab qib K.
