Khoom Taw Qhia

Lub zog siab qis alloy steel (HSLA) yog hom hlau alloy uas muab cov khoom siv kho tshuab zoo dua lossis muaj kev tiv thaiv corrosion ntau dua li cov hlau.Lub zog siab tsis tshua muaj hlau hlau (HSLA) muab kev tiv thaiv ib puag ncig zoo dua thiab muaj zog dua li cov pa roj carbon steel.HSLA tseem yog cov khoom siv zoo heev, yooj yim rau vuam, thiab ua tau zoo heev.HSLA steels tsis yog feem ntau ua kom tau raws li cov tshuaj muaj pes tsawg leeg es tsis txhob lawv paub tias ua tau raws li cov khoom siv kho tshuab.HSLA daim hlau muaj peev xwm txo koj cov nqi khoom siv thiab nce kev them nyiaj vim tias cov khoom siv sib zog tau txais lub zog uas xav tau.Feem ntau siv rau HSLA daim hlau muaj xws li tsheb ciav hlau, tsheb thauj khoom, tsheb thauj khoom, cranes, excavating khoom, vaj tse, thiab txuas hniav thiab cov tswv cuab, qhov twg kev txuag hauv qhov hnyav thiab ntxiv dag zog yog qhov tseem ceeb.

16 mn yog qib steel loj ntawm lub zog siab qis alloy steel phaj nyob rau hauv feem ntau industries, Kev noj ntawm hom no loj heev.Nws qhov kev siv zog yog siab dua li cov pa roj carbon zoo tib yam Q235 los ntawm 20% ~ 30%, atmospheric corrosion kuj los ntawm 20% ~ 38%.

15 MNVN feem ntau yog siv los ua nruab nrab lub zog steel phaj.Nws yog featured nrog siab zog thiab toughness, zoo weldability thiab tsis tshua muaj kub toughness thiab yog dav siv nyob rau hauv kev tsim cov choj, boilers, ships thiab lwm yam loj qauv.

Lub zog theem siab tshaj 500 Mpa, qis carbon alloy steel phaj tsis muaj peev xwm ua tau raws li qhov yuav tsum tau ua, cov pa roj carbon tsawg bainite steel phaj yog tsim.Ntxiv nrog rau cov ntsiab lus xws li Cr, Mo, Mn, B, los pab steel phaj hauv kev tsim bainite lub koom haum, ua rau nws muaj zog dua, plasticity thiab zoo vuam kev ua tau zoo, nws yog feem ntau siv nyob rau hauv siab boiler, siab hlab ntsha, thiab lwm yam Alloy steel phaj. yog tsuas yog siv rau kev tsim choj, nkoj, tsheb, boiler, siab nkoj, roj pipelines, loj steel qauv.
