** 1. Puas yog hss kub dov lossis cold so? **
Hollow cov ntu (hss) feem ntau ** dov txias **. Lawv tsim los ntawm kev noj kub - rolled steel chev thiab txias} ua rau nws mus rau hauv ib puag ncig, lossis duab plaub. Qhov kawg tsim thiab vuam ntawm cov leeg khi ntawm chav tsev kub, uas muab cov steel ib tug du, ua tiav nto thiab ua tiav lub zog. Txawm li cas los xij, cov khoom pib yog kub - rolled steel {{6- kev sib sau.
** 2. Peb Hom Hlau Hlau Hlau Yog Dab Tsi? **
Muaj ntau txoj hauv kev los categorize kub - polled steel, tab sis peb hom qauv raws lawv daim ntawv thiab daim ntawv thov yog:
* ** Hold {{- rolled qauv txheej txheem steel: ** Siv hauv kev tsim kho rau ntas, kab teeb (zoo li kuv} Beachs), thiab raws. A36 hlau yog tus qauv zoo nkauj.
* ** Hold {{{- rolled steel tuav: ** Cov no tuaj nyob rau hauv ntau yam duab (puag ncig, tiaj, thiab yog cov khoom siv raw rau kev ua ntxiv.
* ** KUB {{- rolled steel ntawv / phaj: ** Ntau cov khoom siv, cov khoom siv sib dhos, thiab raws li pib cov khoom txias- rolled txheeb.
** 3. Puas yog HSS qib B lossis C? **
Qhov no yog ib qho tshwm sim ntawm kev tsis meej pem. "Qib B" thiab "Qib C" thiab xa mus rau qib ** siab -}} aliet) hlau ** hauv qab ATTM A572 tus qauv. ** HSS (Hollow cov qauv sib txawv) ** yog tswj hwm los ntawm cov qauv sib txawv, ** ASTM A500 **. Cov qhab nia feem ntau rau HSS yog ** A500 qib b ** thiab ** A500 qib C **. Yog li, tus tswv cuab HSS tuaj yeem yog * A500 Qib B * lossis * A500 Qib C *, tab sis nws tsis zoo li tus "qib B / C" los ntawm A572 tus qauv rau cov phiaj thiab tuav.
** 4. Yog 1018 steel kub dov los yog cold so? **
** 1018 STEEL muaj nyob rau hauv ob qho kub - rolled thiab txias- tus hlau muaj kwv yees li 0.18% carbon). Lo lus "kub {{{{- dov" lossis "txias- dov" piav qhia kev tsim khoom.
* ** Hold {{-}}}}}}}}}}}}}}} Puas muaj qhov chaw ntxhib thiab yog qhov ua kom haum rau qhov tsis tseem ceeb.
* ** Cold -}}}}} (CRS) ** Muaj qhov chaw du, ua tiav qhov ntev, thiab lub zog dua. Nws feem ntau siv rau machining thiab precision seem.
** 5. Yog 1018 tib yam li A36? **
Tsis yog, ** 1018 thiab A36 tsis zoo li qub. ** Lawv yog ob qib sib txawv ntawm cov hlau nrog qhov sib txawv ntawm cov ntsiab lus:
* ** Kev faib tawm: ** A36 yog EF36 yog tus me ntxhais hlau sib txawv ** los ntawm nws cov khoom siv tshuab (feem ntau}
* ** Lub zog: ** A36 muaj tsawg kawg lub zog ntawm 36}}} psi rau txias {} {9} {dov.
* ** Cov tshuaj chemistry: ** Cov tshuaj lom neeg muaj kuab lom ntawm A36 tuaj yeem sib txawv raws li cov khoom siv tshuab, ua rau nws muaj ntau yam tshuaj tua hluav taws xob thiab machining.
* ** SIV: ** A36 yog qhov zoo tshaj plaws rau cov ntawv thov zoo li cov tuam tsev thiab cov choj. 1018 zoo dua rau cov ntu uas muaj txiaj ntsig zoo ntawm lub zog thiab ductility.
