ASTM A572 Qib 55belongs rau tsev neeg ntawmsiab - lub zog, qis -} alloy (hsla) qauv qauv hlau, tsim rau kev xav tau thauj khoom - Cov ntaub ntawv thov cov kabmob uas xav tauMuaj ntau yam tawm dag zog tshaj Qib 50thaum tswjductility thiab formabilityCov. Txhim kho nrogColumbium (Niobium), Vanadium, thiab qee zaumtooj liab, cov hlau ua yeeb yam noKev qaug zog zoo heev thiab kev cuam tshuam tsis kam.
Nws yog nquag siv nyob rau hauvChoj lub lawj, ntev {{{{{{}}} Spanish cov tsiaj qus, thiab cov pa hluav taws, qhov twgLub zog - rau - qhov hnyav ua haujlwmthiabModerate Atmospheric Corrosion Kujyog qhov tseem ceeb. Vim nwsWeldable thiab tsim cov yam ntxwv, Astm A572 Qib 55 yog qhov zoo raubolted, riveted, lossis welded cov rooj sib thamNyob rau hauv high - Kev ua haujlwm engineering.
