Qhov ntom ntawm 1.4306 Stainless Hlau Phaj thiab Ntsuas Qhov Ntsuas
Tso lus
Tus nqi ntom rau 1.4306 Stainless Hlau
1.4306 yog cov khoom siv nyob sab Europe tus lej rau qis-carbon austenitic stainless hlau X2CrNi19-11, sib npaug rau AISI 304L / UNS S30403 thiab rau Suav qib 022Cr19Ni10. Nws qhov ceev yog 7.90 g / cm3, los yog 7900 kg / m3, uas yog tus nqi teev nyob rau hauv EN 10088-1 rau 18-8 austenitic tsev neeg. Qee phau ntawv qhia thiab daim ntawv pov thawj zeb hais txog 7.93 g / cm3 rau tib yam khoom; qhov sib txawv yog nyob rau hauv ib nrab ib xees thiab tshwm sim los ntawm txoj kev ntsuas thiab los ntawm ib txwm variations nyob rau hauv muaj pes tsawg leeg ntawm heats.
Qhov ntom ntom tsis yog cov khoom sib txawv ntawm cov qib raws li qhov muaj zog tawm los. Nws hloov pauv tsuas yog nrog cov ntsiab lus alloy, thiab vim tias txhua qhov cua sov ntawm 1.4306 zaum nyob rau hauv qhov nqaim muaj pes tsawg leeg, qhov ntom ntawm cov phaj hauv pem teb tuaj yeem raug coj mus tas li rau kev suav cov hom phiaj. Qhov tseem ceeb ntawm kev lag luam yog tias tus neeg yuav khoom thiab tus neeg muag khoom siv tib daim duab, vim tias qhov sib txawv ntawm 0.4% qhov ntom dhau los ua 0.4% qhov sib txawv ntawm qhov hnyav ntawm daim ntawv xaj loj.
Qhov twg muaj nuj nqis los ntawm
TS EN 10088-1 Cov khoom siv lub cev ntawm cov hlau tsis muaj steel, suav nrog qhov ntom ntom, cov qauv ntawm elasticity, thermal conductivity thiab hluav taws xob tiv taus, rau txhua qib hauv EN 10088 series. Rau 1.4306 cov ntaub ntawv tseem ceeb yog qhov ceev ntawm 7900 kg / m3, modulus ntawm elasticity ntawm 200 GPa, thermal conductivity ntawm txog 15 W / (m K) ntawm chav tsev kub thiab qhov kub ntawm txog 500 J / (kg K). Cov nuj nqis no yog siv rau kev ntsuas qhov hnyav, rau kev tsim qauv thiab thermal qauv thiab rau kev txheeb xyuas cov ntawv pov thawj.
Cov muaj pes tsawg leeg ntawm 1.4306 yog teem los ntawm EN 10088-2 li carbon 0.030% siab tshaj plaws, chromium 18.0 - 20.0% thiab npib tsib xee 10.0 - 12.0%, silicon 1.00%, manganese 2.00%, phosphorus 0.045% thiab sulfur 1% maxima 0.01 nitrogen Cov ntsiab lus npib tsib xee ntau dua piv nrog 1.4301 yog qhov txawv ntawm qib thiab muab kev ua tau zoo dua tom qab vuam.
Why Density Matters in Procurement and Design
Hauv kev yuav khoom, qhov ceev hloov pauv qhov theoretical loj rau hauv qhov kev txiav txim hnyav, thiab feem ntau phaj yog yuav ntawm qhov hnyav. Hauv kev xa khoom, nws txiav txim siab txog cov phiaj xwm thauj khoom thiab cov nplooj ntawv uas tuaj yeem nqa tau hauv lub thawv hauv qhov tso cai them nyiaj. Nyob rau hauv kev tsim, nws teev cov tuag load ntawm ib tug qauv thiab yog ib tug ncaj qha input rau lub loj xam nyob rau hauv lub teeb yuag engineering. Hauv kev tsim khoom, nws yog lub hauv paus ntawm qhov ntsuas qhov hnyav uas lees paub tias daim ntawv xa khoom sib tw nrog nws cov nominal thickness, uas yog ib qho yooj yim thiab siv tau zoo los soj ntsuam cov cuab yeej.
Vim hais tias austenitic stainless hlau tsis yog -sib nqus, ib qho kev ntsuam xyuas sib nqus tsis tuaj yeem siv los txheeb xyuas qib, thiab kev xam qhov ceev feem ntau yog thawj tus lej kuaj ua ntej xa khoom. Ib daim ntawv uas ntsuas qhov hnyav yog ntau tshaj li ob peb feem pua hauv qab ntawm daim duab suav feem ntau yog nyob rau hauv thickness ntau dua li ntawm cov hlau tsis raug, thiab cov thickness yuav tsum raug txheeb xyuas ncaj qha.
Qhov hnyav ntawm kev xam cov qauv
Rau ib lub phaj tiaj tiaj ntawm cov duab plaub qhov kev suav yog ncaj nraim:
Qhov hnyav (kg)=Thickness (mm) x Dav (mm) x Length (mm) x 7.90 / 1000000
Qhov tuab, dav thiab ntev yog nyob rau hauv millimeters, 7.90 yog qhov ceev hauv g / cm3, thiab qhov tshwm sim yog nyob rau hauv kilograms vim hais tias ib lub cubic millimeter sib npaug 0.001 cm3. Rau lub raj thiab bar, tib lub ntsiab cai siv nrog tus ntoo khaub lig uas tsim nyog -sectional cheeb tsam hloov rau thaj tsam phaj.
| Thickness, hli | 1000 x 2000 mm, kg | 1250 x 2500 hli, kg | 1500 x 3000 mm, kg |
|---|---|---|---|
| 0.5 | 7.90 | 12.34 | 17.78 |
| 1.0 | 15.80 | 24.69 | 35.55 |

| 10.0 | 158.00 | 246.88 | 355.50 |
| 12.0 | 189.60 | 296.25 | 426.60 |
Tolerances thiab cov tswv yim sau tseg
Lub rooj qhov tseem ceeb yog nominal thiab xav tias daim ntawv yog tag nrho nominal thickness. Qhov hnyav tiag tiag sib txawv nrog cov tuab tuab tau tso cai los ntawm kev tswj hwm kev qhia tshwj xeeb: ASTM A480 / A480M tswj hwm qhov hloov pauv tau tso cai rau cov phaj xaj rau ASTM A240 / A240M, thaum EN ISO 9444-1 thiab EN ISO 9445-1/-2 GB kav cov khoom txias hauv Europe thiab dov 3280 thiab GB / T 4237 siv hauv Suav teb. Ib daim ntawv dov ntawm tus minus sab ntawm qhov kev kam rau siab tuaj yeem hnyav peb mus rau tsib feem pua tsawg dua li tus lej nominal yam tsis tau ua raws.
Rau cov nqi, daim duab ceev yuav tsum tau kho nyob rau hauv kev nug txog kev yuav khoom kom cov quotations tuaj yeem muab piv rau zoo li. Qhov twg ib qhov project yuav tsum muaj kev tswj qhov hnyav dua li tus qauv kam rau ua, yuav tsum tau txiav txim siab txwv tsis pub, thiab qhov no yuav tsum tau hais meej meej dua li qhov xav tau.
