Ib qho ntawm cov yam ntxwv tseem ceeb ntawm SPHD steel yog nws cov formability zoo heev. Nws tuaj yeem ua tau yooj yim zoo li tus thiab tsim rau hauv qhov nyuaj uas siv ntau yam kev tsim khoom xws li stamping, dabtsi yog khoov, thiab kos duab sib sib zog nqus. Qhov no ua rau nws tsim nyog rau cov ntawv thov hauv kev lag luam tsheb, qhov twg nws yog siv los tsim lub cev panels, fenders, thiab lwm yam khoom uas xav tau cov duab nyuaj.
Cov hlau kuj muaj qhov zoo weldability, tso cai rau kev sib koom ua ke ntawm qhov chaw yooj yim thaum tsim khoom. Qhov no yog qhov tseem ceeb rau cov ntawv thov uas ntau yam khoom yuav tsum tau sib sau ua ke los ua ib qho qauv loj.
Nyob rau hauv cov nqe lus ntawm txhua yam khoom, SPHD steel muaj ib tug kuj tsis tshua muaj yield zog thiab siab elongation, uas qhia tau hais tias nws muaj peev xwm deform yam tsis muaj fracturing. Cov cuab yeej no yog qhov tseem ceeb rau kev siv daim duab sib sib zog nqus, vim nws tso cai rau cov hlau kom ncav thiab tsim yam tsis muaj kev tawg.
SPHD steel kuj paub txog nws qhov zoo ntawm qhov zoo. Cov txheej txheem kub dov ua rau lub ntsej muag du thiab zoo ib yam, uas yog qhov tseem ceeb rau kev siv qhov zoo li qhov kev xav.
Zuag qhia tag nrho, SPHD steel yog ntau yam khoom siv nrog zoo heev formability, weldability, thiab mechanical zog. Nws cov ntawv thov hauv tsheb thiab lwm yam kev lag luam ua rau nws yog ib qho khoom siv tseem ceeb rau ntau yam kev tsim khoom.
