SA588 Qib C yog dab tsi?
SA588 Qib C yog asiab- zog, qis- alloy (HSLA) cov qauv hlaunrog txhim kho atmospheric corrosion kuj, teev nyob rau hauvASTM A588 Cov Lus Qhia Tshwj Xeeb. Nws yog tsim rauhnyav -cov haujlwm ua haujlwmraug rau ib puag ncig, xws li txuas hniav, kev lag luam moj khaum, thiab cov tsev sab nraum zoov. Cov hlau muabzoo weldability, toughness, thiab formability, haum rau ntev - siv sab nraum zoov nrog txo kev saib xyuas.

Kev tsom xam
Strength Progression:A < B < C < K. Qib K muaj qhovsiab tshaj tawm los thiab tensile zog, haum rau qhov hnyav tshaj plaws.
Corrosion Resistance:Txhua qib muaj kev tiv thaiv zoo heev atmospheric corrosion, txo kev txij nkawm rau kev siv sab nraum zoov.
Daim ntawv thov:
Qib A: nruab nrab ntawm cov khoom siv thauj khoom
Qib B: siab dua loads A
Qib C: hnyav-cov haujlwm sab nraum zoov
Qib K: feem ntau xav tau cov qauv siv uas xav tau lub zog siab tshaj plaws
