Nyob rau hauv lub ntiaj teb no ntawm structural engineering thiab manufacturing, xaiv cov qib steel zoo yuav ua tau tag nrho cov sib txawv nyob rau hauv qhov project durability, nqi -efficiency, thiab ua raws li cov kev cai thoob ntiaj teb.
Kab lus no nkag mus tob rau hauvSS400 hlauCov qib sib npaug, muab cov ncauj lus kom ntxaws sib piv los pab cov engineers, cov kws tshaj lij kev yuav khoom, thiab cov kws tshaj lij kev lag luam ua cov kev txiav txim siab.
Nkag siab SS400 Steel: Ib Tus Qauv Nyij Pooj rau Kev Siv Cov Qauv
SIB 400yog cov qauv siv dav siv hauv qib steel raws li Japanese Cov Qauv Kev Lag Luam (JIS G3101). Nws tau paub txog nws qhov zoo tshaj plaws weldability, machinability, thiab pheej yig, ua rau nws zoo tagnrho rau kev tsim kho, txuas hniav, nkoj, thiab tshuab. Tab sis thaum muab cov khoom siv thoob ntiaj teb, kev nkag siab SS400 steel qib sib npaug yog qhov tseem ceeb los xyuas kom muaj kev sib raug zoo thiab kev ua haujlwm.
Cov khoom tseem ceeb ntawm SS400 steel suav nrog
- Tensile zog: 400-510 MPa
- Yield Strength: Yam tsawg kawg 245 MPa (rau thicknesses Tsawg dua los yog sib npaug li 16 hli)
- Elongation: 17-21% (nyob ntawm thickness)
- Tshuaj muaj pes tsawg leeg: Carbon (C) Tsawg dua lossis sib npaug li 0.25%, Manganese (Mn) Tsawg dua lossis sib npaug li 1.60%, Phosphorus (P) Tsawg dua lossis sib npaug li 0.050%, Sulfur (S) Tsawg dua lossis sib npaug li 0.050%
SS400 tsis yog cua sov- kho thiab feem ntau yog muab rau hauv daim ntawv kub -rolled. Nws qhov kev ua tau zoo tau ua rau muaj kev sib piv tsis tu ncua nrog cov qauv thoob ntiaj teb, tshwj xeeb tshaj yog nyob rau hauv txoj haujlwm hla - ciam teb.
SS400 Steel sib npaug rau S235JR: Ib qho piv txwv ncaj qha
Ib qho ntawm cov lus nug feem ntau yog seb SS400 steel puas sib npaug rau S235JR, European tus qauv raws li EN 10025-2.
Cov lus teb luv luv? Yog lawm, lawv feem ntau suav hais tias hloov pauv tau hauv ntau daim ntawv thov, tab sis cia peb tshuaj xyuas cov ntsiab lus.
S235JR yog ib qho uas tsis yog- alloy structural steel nrov nyob hauv Europe rau kev tsim cov qauv, cov khoom siv, thiab kev tsim khoom.
Nov yog ib sab -los ntawm- sab piv:
Thaum SS400 steel sib npaug rau S235JR muaj tseeb rau kev siv cov qauv me me, S235JR muaj cov ntsiab lus qis me ntsis, uas tuaj yeem txhim kho weldability hauv qee qhov chaw. Txawm li cas los xij, SS400 lub zog muaj zog ntau dua hauv cov ntu nyias ua rau nws nyiam rau qee qhov haujlwm Japanese lossis Asian. Yog tias koj tab tom nug "SS400 vs S235JR steel qib," nco ntsoov tias ob qho tib si haum rau cov ntawv tsis yog - tseem ceeb, tab sis ib txwm txheeb xyuas nrog cov phiaj xwm tshwj xeeb kom tsis txhob muaj qhov tsis sib xws.
Lwm qhov sib npaug thoob ntiaj teb ntawm SS400 Steel
Tshaj li S235JR, SS400 muaj qhov sib npaug hauv ntau cov qauv thoob ntiaj teb.
Ntawm no yog ib daim ntawv teev npe ntawm SS400 steel qib sib npaug thoob plaws cheeb tsam:
ASTM (USA):ASTM A36 yog qhov ze tshaj plaws SS400 steel sib npaug hauv ASTM cov qauv. Ob leeg sib koom cov cuab yeej cuab tam zoo sib xws thiab siv rau kev tsim qauv. Tawm Zog: 250 MPa (A36) vs 245 MPa (SS400)
GB (Tuam Tshoj): Q235B hauv qab GB / T 700 yog qhov sib tw muaj zog. Nws muaj dav thiab raug nqi - zoo rau kev tsim khoom. "SS400 steel sib npaug hauv Suav qauv" feem ntau taw qhia rau Q235B vim qhov sib piv tensile zog (370-500 MPa).
DIN (Lub teb chaws Yelemees): St37-2 (DIN 17100) yog qhov sib npaug qub, tam sim no feem ntau hloov los ntawm S235JR hauv Tebchaws Europe. Mechanical zoo sib xws: tawm los ~ 235 MPa.
BS (UK): 40B nyob rau hauv BS 4360 ua tib zoo nrog SS400 cov khoom. Pab tau rau cov haujlwm qub qub qub qub hauv tebchaws Askiv.
Rau kev siv ceev, ntawm no yog ib lub rooj ntawm SS400 steel sib npaug:
Cov SS400 steel sib npaug thoob ntiaj teb cov qauv ua kom muaj kev sib koom ua ke hauv cov khoom siv thoob ntiaj teb. Txawm li cas los xij, qhov sib npaug tsis yog ib txwm muaj tseeb- yam xws li kev sim cuam tshuam (piv txwv li, S235JR xav tau Charpy V- qhov ntsuas ntsuas) tuaj yeem sib txawv.

FAQ
Q: SS400 steel khoom yog dab tsi?
A: SS400 yog cov qauv hlau nrog lub zog tensile siab, sib npaug ntawm 400N / mm² lossis ntau dua. SS400 paub txog qhov pheej yig dua thiab siv tau piv rau lwm cov ntaub ntawv hlau. Nws kuj yog ib qho yooj yim rau txheej txheem los ntawm txoj kev xws li vuam thiab txiav.
Q: Puas yog SS400 zoo ib yam li A36?
A: ASTM tus qauv A36 steel thiab JIS tus qauv SS400 steel tshuaj muaj pes tsawg leeg kuj zoo ib yam. JIS SS400 steel yog ASTM A36 cov khoom sib npaug. Ob leeg ASTM A36 SS400 steel yog tsim los rau kev tsim qauv. Hauv cov ntawv thov sib txawv, ASTM A36 SS400 cov cuab yeej cuab tam tuaj yeem ua tiav tib lub hom phiaj.
Q: Qhov txawv ntawm SS400 thiab ss304 yog dab tsi?
A: 304 stainless hlau muaj qis nickel cov ntsiab lus thiab tej zaum yuav sib nqus me me. Lub caij no, 400-series stainless hlau yog me ntsis sib nqus, vim nws tsis muaj nickel. Qhov no tsis yog qhov tseem ceeb ntawm kev txiav txim siab thaum xaiv ib lub stainless hlau fastener.
Q: Puas yog SS400 qis carbon steel?
A: SS400 yog cov pa roj carbon tsawg uas tsis muaj cov ntsiab lus carbon. Raws li nws cov khoom siv kho tshuab, nws zoo ib yam li ASTM A36 uas yog siv dav hauv engineering thiab kev siv tshuab. Tus qauv JIS SS400 steel lub kaum sab xis yog tus nqi qis dua -tsawg dua thiab qhia tau zoo hauv cov haujlwm loj hauv engineering.
