Tsim tshwj xeeb rau Mechanical Seamless Carbon Steel Tube Pipe, Txheej Txheem Hlau Yeeb Nkab Dia 457mm 420mm 380mm 365mm 27simn 45mn2 42CrMo4 Q + T 41cr4
Lus piav qhia luv luv:
27SiMn steel kav yog dav siv nyob rau hauv tsheb, roj av, tshuaj thiab shipping industries.27SiMn steel yeeb nkab yog normalized thiab tempered, thiab coated nrog phosphate sab hauv thiab sab nraud.Cov yeeb nkab steel no tsuas yog siv rau hauv lub xeev quenched thiab tempered los tsim kub stamping qhov chaw (hydraulic qhov chaw) yuav tsum muaj siab toughness thiab hnav tsis kam, thiab kub stamping qhov chaw yuav tsum muaj siab toughness thiab hnav tsis kam.
27SiMn seamless steel yeeb nkab muaj siab hardenability, qhov tseem ceeb hardenability txoj kab uas hla hauv dej yog 8 ~ 22 hli, zoo machinability, nruab nrab txias deformation plasticity thiab weldability;Tsis tas li ntawd, lub toughness ntawm cov yeeb nkab steel tsis txo qis thaum kho cua sov, tab sis nws muaj zog heev thiab hnav tsis kam, tshwj xeeb tshaj yog nyob rau hauv dej quenching.
Peb lub hom phiaj yog feem ntau los sib sau ua ke thiab txhim kho qhov zoo thiab kev pabcuam ntawm cov kev daws teeb meem uas twb muaj lawm, lub sijhawm no tsis tu ncua tsim cov khoom tshiab kom tau raws li cov neeg siv khoom tshwj xeeb 'yuav tsum tau tsim tshwj xeeb rau Mechanical Seamless Carbon Steel Tube Pipe, Txheej Txheem Hlau Yeeb Nkab Dia 457mm 420mm 380mm 365mm 27simn 45mn2 42CrMo4 Q + T 41cr4, Ua ke nrog peb cov kev sim siab, peb cov khoom thiab cov kev daws teeb meem tau txais kev ntseeg siab ntawm cov neeg yuav khoom thiab tau txais txiaj ntsig zoo ntawm ob qho no thiab txawv teb chaws.
Peb lub hom phiaj yog feem ntau los sib sau ua ke thiab txhim kho qhov zoo thiab kev pabcuam ntawm cov kev daws teeb meem uas twb muaj lawm, lub sijhawm no txuas ntxiv tsim cov khoom tshiab kom tau raws li cov neeg siv khoom tshwj xeeb 'xav tau rauTuam Tshoj Steel Yeeb Nkab 41cr4 thiab Hlau Yeeb Nkab 45mn2, Peb txais tos cov neeg siv khoom los ntawm thoob plaws lub ntiaj teb tuaj tham txog kev lag luam.Peb muab cov kev daws teeb meem zoo, tus nqi tsim nyog thiab cov kev pabcuam zoo.Peb cia siab tias yuav tsim kev lag luam kev sib raug zoo nrog cov neeg siv khoom hauv tsev thiab txawv teb chaws, sib koom ua ke kom muaj kev vam meej tag kis.
