Dab tsi yog cov cuab yeej cuab tam cov cuab yeej ntsuas ntawm Q235NH? -} kev paub

Cov cuab yeej siv cov khoom ntiag tug ntawm Q235NH (qhov qis {1} {ali171) tau hais meej, thiab txheej txheem hauv cov chaw muaj peev xwm ntawm atmospherity corrosion. Cov ntsuas no feem ntau yog kuaj rauKub - rolled lossis li qub steel daim hlau / nplooj ntawvthiab suav nrog cov hauv qab no cov qauv tseem ceeb:

1. Cov cim dag zog (tseem ceeb rau load - bearing)

Cov ntsuas kev qhia ua rau cov hlau muaj peev xwm tiv thaiv deformation thiab pob txha lov hauv qab ntawm cov nra hnyav, uas yog qhov tseem ceeb rau kev nyab xeeb.

Qhov taw qhia lub npe	Lub cim	Zaj piav	Cov kev xav tau (tuab tsawg dua lossis sib npaug rau 16 hli, GB / T 4171)
Yield zog (RES)	Nyob	Qhov kev ntxhov siab uas tus hlau pib yauv nyom (tsis muaj dua tshiab).	Ntau dua los yog sib luag rau 235 MPa ("235" hauv Q235NH hais txog qhov tsawg kawg nkaus zog)
Lub zog tensile (RM)	Rm	Qhov siab tshaj plaws kev ntxhov siab cov hlau tuaj yeem tiv taus ua ntej tawg thaum muaj kev ntxhov siab.	375 - 500 MPA

2. Cov khoom siv muaj zog (tiv taus brittle bacture)

Versastic muaj kev cuam tshuam cov hlau muaj peev xwm kom yauv tsis zoo ua ntej kev sib tw ua ntej kev sib tw, ua kom nruj kev du ncauj, ua kom tsis txhob muaj tseeb nkig.

Qhov taw qhia lub npe	Lub cim	Zaj piav	Cov kev xav tau (tuab tsawg dua lossis sib npaug rau 16 hli, GB / T 4171)
Elongation tom qab pob txha lov (a)	A	Qhov feem pua ntawm cov qauv qhov ntev nce tom qab tawg tom qab tawg (xam los ntawm lub ntsuas cua ntev).	Ntau dua los yog sib npaug rau 22% (rau cov qauv ntsuas ntsuas ntev ntawm 50 hli, a50)

3. Kev qhia kev ua tiav (tawm tsam qis - kub / kev puas tsuaj)

Kev ntsuas kev ntsuas tus hlau muaj peev xwm nqus hluav taws xob thaum cuam tshuam rau kev tawm tsam cov rog dynamic (piv txwv li cov cua, kev co) thiab zam kev qis- kub tawm.

Qhov taw qhia lub npe	Lub cim	Kev Ntsuas Mob	Yuav Tsum Tau (GB / T 4171)
Cuam Tshuam Lub Zog (KV2)	KV2	Charpy V - cov qauv notch; kuaj ntawm-40 Qib(qauv qis - huab cua kub rau huab cua cov hlau).	Ntau dua los yog sib npaug rau 34 j (ib qho qauv piv txwv; nruab nrab ntawm 3 kuaj ntau dua lossis sib npaug rau 39 J)

4. Qhov Yuav Tsum Muaj Ntxiv Cov Tseem Ceeb: Bend Xeem (Cov Txheej Txheem & Kev Sib Koom Tes)

Bend xeem ntsuas cov hlau txias - Txoj kev ua tau zoo thiab muaj kev sib tsoo hauv kev sib tsoo, dov, dov, lossis vuam.

Ntsuas Yam	Kev Ntsuas Mob	Qhov toob kas
Cold Bend Xeem	Piv txwv tuab tsawg dua lossis sib npaug rau 16 hli; Dabtsi yog khoov kaum sab xis=180 degree; Sab hauv khoov radius=1.5 × qauv tuab (d).	Tsis muaj cov kab nrib pleb, sib cais, lossis pom tsis xws luag nyob sab nraud ntawm cov qauv bent.

Tseem ceeb rau cov ntawv rau kev hloov pauv

Kev cia siab thickness: Rau cov phiaj hlau tuab tshaj 16 hli (piv txwv li, muaj zog dua lossis muaj txiaj ntsig zoo dua lossis muaj txiaj ntsig zoo dua lossis muaj txiaj ntsig zoo dua lossis sib npaug

Mill xeem Daim Ntawv Pov Thawj (MTC): Cov yam ntxwv tiag tiag ntawm ib qho tshwj xeeb batch ntawm Q235NH yuav tsum tau txheeb xyuas ntawm MTC muab los ntawm cov chaw tsim khoom, raws li cov kev hloov me me tuaj yeem muaj nyob ntawm ntau ntau.

Kev sib piv nrog cov hlau loj: Muab piv rau cov pa roj carbon steel qu235, Q235N yog lub zog zoo sib xws tab sis Q235's Degree Dolosion (Vim yog Alloy Elosing Xws li Cu, CR).
