Imiqathango yokuhanjiswa kwe-BS EN 10210

JR, J0, J2 kunye ne-K2 - kushushu kugqityiwe.

N kunye ne-NL - eqhelekileyo.I-normalized ibandakanya i-normalized rolled.

JR, J0, J2 kunye ne-K2 - eshushu yasebenza

I-N kunye ne-NL - Ukulungelelanisa.I-normalizing ibandakanya ukuqengqeleka okuqhelekileyo.

Kusenokuba yimfuneko kumacandelo angenamngxunya angenamthungo anobunzima bodonga ngaphezulu kwe-10 mm, okanye xa iT/D ingaphezulu kwe-0,1, ukusebenzisa ukupholisa okukhawulezileyo emva kokwenza i-austenitizing ukufezekisa ubume obucetyiweyo, okanye ukucinywa kolwelo kunye nokufudumeza ukufikelela komatshini ochaziweyo. iipropati.

Kumacandelo angenamgongxo anobunzima bodonga obudlula i-10 mm, okanye xa i-T/D ingaphezulu kwe-0.1, ukupholisa okukhawulezileyo emva kokwenziwa kwe-austenitization kunokufuneka ukuphumeza isakhiwo esinqwenelekayo, okanye ukucinywa kolwelo kunye nokufudumeza ukufikelela kwiipropati ezichaziweyo zoomatshini.

Ukubunjwa kwemichiza ye-BS EN 10210

Iintsimbi ze-non-alloy - Ukubunjwa kweekhemikhali

I-BS EN 10210 Ukwakheka kwemichiza A.1

Fine Grain Steels - Ukubunjwa kwemichiza

I-BS EN 10210 Ukwakhiwa kwemichiza B.1

Xa kumiselwa i-CEV le fomyula ilandelayo iya kusetyenziswa:

CEV=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15

Ukutenxa ekuBumbeni kweMichiza

I-BS EN 10210 ukutenxa okuvumelekileyo kokwakheka kweekhemikhali

IiPropati zoomatshini ze-BS EN 10210

Ukuthomalalisa uxinzelelo kuxinzelelo olungaphezulu kwama-580 °C okanye ngaphezulu kweyure enye kunokukhokelela ekuwohlokeni kweempawu zoomatshini.

Iintsimbi ze-non-alloy - iiPropati zoomatshini

I-BS EN 10210 Iipropati zoomatshini A.3

Fine Grain Steels - Mechanical Properties

I-BS EN 10210 Iipropati zoomatshini B.3

Iimvavanyo zempembelelo

Uvavanyo lwempembelelo ayifunwa xa ubukhulu obuchaziweyo < yi-6 mm.

Iisampulu ezikumgangatho oqhelekileyo we-V ngokwe-EN 10045-1 ziya kusetyenziswa.

Ukuba ubukhulu bemveliso yegama abunelanga ukulungiselela imizekelo esemgangathweni, iimvavanyo ziya kuqhutywa kusetyenziswa imizekelo enobubanzi obungaphantsi kwe-10 mm, kodwa ingabi ngaphantsi kwe-5 mm.

Ukuweldability

Iintsimbi kwi-BS EN 10210 ziyakwazi ukuwelda.

I-EN 1011-1 kunye ne-EN 1011-2 ichaza iimfuno ngokubanzi kwiimveliso ezidityanisiweyo.

Ukuqhekeka okubandayo kwindawo ye-weld ngowona mngcipheko uphambili njengoko ubukhulu bemveliso, inqanaba lamandla, kunye nokunyuka kwe-CEV.

Ukunyamezelwa kweDimensional

Ukunyamezela kwiMilo, ukuTwa kunye noMisa

I-BS EN 10210 Unyamezelo kwimilo, ukuthi tye kunye nobunzima

Ukunyamezela Ubude

I-BS EN 10210 Ukunyamezela ubude

Umthungo Ubude be-SAW Weld

Unyamezelo kubude bomthungo we-weld wangaphakathi nangaphandle kumacandelo angaphakathi adityanisiweyo we-arc.

Ukutyeba, T Ubude be-weld bead, mm
≤14,2 3.5
>14,2 4.8

Umgangatho we-BS EN 10210 ugubungela zombini icandelo elingenamthungo kunye ne-welded eshushu eligqityiweyo.Iinkqubo ze-welding eziphambili zi-resistance welding (ERW) kunye ne-arc welding ephantsi kwamanzi (SAW).I-welds kwimibhobho yensimbi ye-ERW ayibonakali kakhulu, ngelixa ii-welds ze-SAW zihlala zirhabaxa kwaye zibonakala ngakumbi ngenxa ye-SAW.

Imbonakalo yoMphezulu

Umphezulu uya kuba nesiphelo esigudileyo esihambelana nendlela yokuvelisa esetyenzisiweyo;

Ukuba ubukhulu bungaphakathi kokunyamezela, ama-bumps, grooves, okanye i-grooves e-shallow longitudinal ephuma kwinkqubo yokuvelisa ivumelekile.

Iigalvanized

Iimveliso kwi-BS EN 10210 zilungele unyango lwediphu eshushu.

I-EN ISO 1461 kufuneka isetyenziswe ukucacisa iimfuno zokugquma.

Iingubo ze-Zinc zisetyenziselwa ukucwiliswa kwisisombululo esityhidiweyo esiqulethe ubuncinane i-98% ye-zinc content.

Ukulungiswa kweziphene zoMphezulu

Iziphene zobuso zingasuswa ngokusila ngumvelisi, ngaphandle kokuba ubungqingqwa obulungisiweyo abukho ngaphantsi kobuncinci obuvumelekileyo.

Ukuba yenziwe yinkqubo ye-welding, ukulungiswa kwee-welds akuvumelekanga ngaphandle kwe-arc welding ephantsi kwamanzi.

Umbhobho wentsimbi ongeyo-alloyi unokulungiswa ngokuwelda umzimba wombhobho.Umbhobho wentsimbi yealloyi awunakulungiswa ngokuwelda umzimba.

I-BS EN 10210 Ukumakisha

Imixholo yokumakishwa kombhobho wentsimbi kufuneka iqulathe:

ligama lentsimbi, umz. EN 10210-S275JOH.

ligama okanye uphawu lokuthengisa lomenzi.

ikhowudi yokuzazisa, umz. inombolo ye-odolo.

I-TS EN 10210 iityhubhu zensimbi zinokumakishwa ngeendlela ezahlukeneyo zokuqinisekisa ukuchongwa ngokulula kunye nokulandeleka, nokuba kupeyinti, isitampu, iileyibhile ezincamathelayo, okanye iilebhile ezongezelelweyo, ezinokusetyenziswa ngokwahlukeneyo okanye ngokudityaniswayo.

Usetyenziso

Ngenxa yamandla ayo aphezulu, ukuqina okuhle, kunye ne-weldability, i-BS EN 10210 iyakwazi ukumelana noluhlu olubanzi lweemeko kunye neemeko zokulayisha kwaye isetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo zesakhiwo.
