Q345 Txheej txheem cej luam
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. Yog li ntawd, nws yog ib qho tseem ceeb kom nco ntsoov tias tus nqi tawm los txo qis thaum cov khoom thickness nce.
Q345 Cov khoom sib npaug
Q345 kuj tuaj yeem hloov nrog cov khoom sib npaug, suav nrog A572 Qib 50 USA ASTM, Q355 Tuam Tshoj GB / T, thiab SPFC 590 Nyab Laj / Nyiv JIS.
Lub zog tawm los ntawm Q345 yog qhov uas cov khoom pib deform plastically. Ua ntej ntaus deformation, nws yuav rov qab mus rau nws qhov qub qub thaum kev ntxhov siab raug tshem tawm. Rau Q345, lub zog tawm los yog 345 MPa.
Zoo li ntau yam hauv nws qib, nws yuav ua kom ntev ntev ua ntej rub tawm, uas feem ntau tshwm sim ntawm 20 feem pua ntawm nws qhov pib ntev. Q345 muaj qhov ntsuas lub zog tensile ntawm 470 txog 660 MPa, uas txhais tau hais tias nws tuaj yeem ua haujlwm hnyav thiab siv ua ntej ua tsis tau.
Cov cuab yeej vuam ntawm Q345 yuav raug nug los ntawm cov neeg siv kawg, txawm tias cov khoom siv vuam feem ntau cuam tshuam los ntawm cov ntsiab lus tshuaj. Txawm li cas los xij, cov cuab yeej siv tau sai thiab txhim khu kev qha tom qab ntau xyoo ntawm kev tshawb fawb, uas txhais tau hais tias nws yog ib qho zoo heev steel qauv rau cov qauv tsim.
Q345 steel yog los ntawm 16 Mn steel qib, feem ntau tsim nyob rau hauv ib tug kub dov steel kauj los yog ntawv los yog ib tug kub dov steel phaj. Nws yog ib qho kev xaiv zoo heev thaum koj xav tau kev kub siab ntev.
Vim li cas cov khoom siv hlau hauv Channel?
Hlau yog suav tias yog cov hlau zoo tshaj plaws los siv thaum ua cov hlau raws vim nws cov khoom siv kho tshuab.
Hardness: Lub peev xwm los zam qhov deg indentation (localized yas deformation) thiab khawb yog hu ua hardness. Hardness tuaj yeem qhia txog kev khawb tsis kam, puas ua haujlwm, indentation kuj, thiab txawm tias shaping lossis localized yas deformation kuj; yog li ntawd, nws yog kab tias cov khoom siv tsis zoo tshaj plaws. Los ntawm ib qho engineering nam, hardness yog qhov tseem ceeb vim hais tias nws ua rau kom tsis kam hnav los ntawm kev sib txhuam los yog yaig los ntawm chav, roj, thiab dej.
Toughness: Lub peev xwm nqus tau lub zog tsis muaj kev tawg lossis tawg. Toughness kuj yog lub peev xwm ntawm ib yam khoom los tiv thaiv tawg thaum strained. Qhov txawv ntawm toughness thiab hardness yog tias cov khoom uas deforms ntau yam tsis muaj kev tawg tuaj yeem hu ua tawv heev tab sis tsis tawv.
