SA588 Qib A yog dab tsi?
SA588 Qib A yog asiab- zog, qis- alloy (HSLA) cov qauv hlaunrog txhim kho atmospheric corrosion kuj. Nws yog teev nyob rau hauvASTM A588 Cov Lus Qhia Tshwj Xeebthiab yog dav siv rautxuas hniav, cov qauv tsim, cov platforms sab nraum zoov, thiab lwm yam kev siv cov txheej txheem raug huab cua. Cov hlau muajzoo weldability, toughness, thiab formability, ua rau nws haum rau ntev - sab nraum zoov raug yam tsis muaj kev saib xyuas hnyav.

SA588 Qib B yog dab tsi?
SA588 Qib B yog asiab- zog, qis- alloy (HSLA) cov qauv hlaunrog txhim kho atmospheric corrosion kuj, teev nyob rau hauvASTM A588 Cov Lus Qhia Tshwj Xeeb. Piv rau Qib A, nws muajsiab yield zogthiab me ntsis txhim kho tensile zog. Nws yog feem ntau siv raucov txuas hniav, cov tsev, cov qauv sab nraum zoov, thiab lwm yam khoom thauj khoom -cov kabmob uas cuam tshuam rau ib puag ncig. Cov hlau muajzoo weldability, toughness, thiab formability.

Kev tsom xam
Qib B muajsiab dua yield zog thiab me ntsis siab dua tensile zog, ua kom haum rauhnyav dualos yog xav tau ntau yam kev thov.
Ob qib muajzoo heev atmospheric corrosion kujthiab haum rau sab nraum zoov raug.
Qib A yog txaus raunruab nrab loads, thaum Qib B yog nyiam thaumsiab zog los yog hnyav load peev xwmyog xav tau.
