ASTM A656 / A656M Qib 50 yog qhov siab {3} {} {} {} {} {mpa (50 ksi). Tsim los rau cov ntawv thov tsim qauv thiab kev sib sau ua ke uas xav tau txhim kho lub zog {{} Qhov hnyav} Qhov hnyav thiab weldability thaum kev tswj hwm kom zoo.

Cov qib no ua tiav cov khoom siv los ntawm microalloying nrog cov ntsiab xws li Niobium, vanadium, lossis titanium, ua ke nrog cov txheej txheem dov. Nws yog feem ntau siv nyob rau hauv Automotive FRAMES, cov khoom siv tsheb laij teb, khoom siv ua liaj ua teb, thiab cov khoom siv kev tsim kho uas poob ceeb thawj zaug yog qhov tseem ceeb.

Cov hlau muab cov yam ntxwv zoo sib xws thoob plaws ntawm lub kauj dav dav thiab ntev, ua kom muaj kev txhim khu kev qha hauv cov chaw xav tau. Nws cov khoom sib xyaw sib xyaw tso cai rau kev sib piv yooj yim piv rau cov pa hluav taws xob siab {{{{2} {{2} Qhov kev xaiv zoo rau cov qauv kev tsim qauv.
