Q345 SS490 H Beam Steel

Q345 yog cov khoom siv hlau tsis tshua muaj hlau feem ntau siv hauv tsheb, txuas hniav, nkoj, thiab kev tsim kho. Kuj tseem hu ua GB / T 1591, Q qhia txog qhov taw tes tawm los, thiab 345 hais txog lub zog ntawm cov txiaj ntsig. Xws li, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tus nqi tawm los txo qis raws li cov khoom thickness nce.SS490 yog cov qauv kub dov steel uas txhais los ntawm JIS G 3101 tus qauv. Nws yog feem ntau siv rau ntau hom kev siv cov txheej txheem. SS490 muaj zog tensile zoo dua piv rau SS400 steel. Nws yog ua hauj lwm nyob rau hauv thicknesses li ntawm 6 hli mus rau 120 hli. Nws cov tshuaj pleev ib ce muaj xws li qhov siab tshaj plaws ntawm 0.050 feem pua ntawm Phosphorous thiab Sulphur, nrog hlau thiab me impurities. Nws cov khoom siv kho tshuab ua rau nws zoo tagnrho rau kev tsim cov kav dej, kav dej, pas nrig, thiab ntau yam steels.

Khoom Description

Yield zog

Lub zog tawm los yog qhov taw tes tawm los yog cov khoom siv tau txhais raws li qhov kev ntxhov siab uas cov khoom pib deform plastically. Ua ntej qhov taw tes tawm los, cov khoom siv yuav deform elastically thiab yuav rov qab mus rau nws cov duab qub thaum lub zog thov raug tshem tawm. Lub zog ntawm Q345B yog 345 Mega Pascals. Zoo li feem ntau steels ntawm nws qib, nws raug elongation ua ntej nws rub tawm, feem ntau ntawm 20-21 feem pua ntawm nws qhov pib ntev.

Tensile zog

Lub zog tensile ntawm cov khoom siv yog qhov siab tshaj plaws ntawm tensile kev nyuaj siab uas nws tuaj yeem siv ua ntej tsis ua haujlwm, piv txwv li tawg. Steel tensile zog yog qhia nyob rau hauv units ntawm quab yuam muab faib los ntawm cross sectional cheeb tsam; Hauv Metric system, chav tsev no hu ua Pascal. Ib tug Pascal yog ib tug Newton ib square meter. Lub zog tensile ntawm Q345 steel yog nyob ntawm 470 txog 660 Mega Pascals.

Tshuaj muaj pes tsawg leeg

Cov tshuaj muaj pes tsawg leeg ntawm cov qib steel tshwj xeeb no, uas suav nrog cov ntsiab lus xws li carbon, manganese, phosphorous, thiab sulfur, ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws tag nrho cov khoom thiab kev ua haujlwm. Tshwj xeeb, muaj cov pa roj carbon thiab manganese pab txhawb lub zog rau qhov hnyav piv, yog qhov tseem ceeb hauv nws txoj kev siv dav hauv kev tsim kho thiab kev lag luam.

SS490 steel qib qhia tau hais tias muaj kev tiv thaiv corrosion, feem ntau vim nws ua tib zoo sib npaug ntawm phosphorous thiab sulfur. Cov ntsiab lus no, nyob rau hauv qhov tseeb piv, pab txhim kho tag nrho cov weldability ntawm cov khoom, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau kev siv structural thiab mechanical engineering applications.

Tsis tas li ntawd, qhov muaj peev xwm cuam tshuam ib puag ncig ntawm qib steel no yog txo los ntawm qhov muaj peev xwm ntawm nanotechnology txhim kho. Cov txheej txheem siab tshaj no tuaj yeem txhim kho cov khoom siv, yog li txo qhov xav tau hloov pauv thiab ua rau muaj kev ruaj ntseg.
