Tus nqi qis tshaj rau Cov Chaw Tsim Tshuaj 20 # / 45 # / 27simn / 30crmosia Hydraulic Prop Pipe Seamless Carbon Steel Pipe
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.
Tsuas yog hais txog txhua tus tswv cuab los ntawm peb cov neeg ua haujlwm tau nyiaj ntau qhov tseem ceeb rau cov neeg siv khoom xav tau thiab kev lag luam kev sib txuas lus rau Tus Nqi qis tshaj plaws rau Cov Chaw Tsim Khoom 20 # / 45 # / 27simn / 30crmosia Hydraulic Prop Pipe Seamless Carbon Steel Pipe, Peb cov neeg siv khoom feem ntau xa tawm hauv North America, Africa thiab Eastern Europe.peb tuaj yeem yooj yim qhov kev daws teeb meem zoo nrog rau tus nqi zoo nkauj heev.
Tsuas yog hais txog txhua tus tswv cuab los ntawm peb cov neeg ua haujlwm tau txais txiaj ntsig loj ua rau cov neeg siv khoom xav tau thiab kev sib txuas lus kev lag luam rauTuam Tshoj Hydraulic Prop Yeeb Nkab thiab 20 # / 45 # Hlau Yeeb Nkab, Peb lub hom phiaj los tsim kom muaj lub npe nrov uas tuaj yeem cuam tshuam rau qee pawg neeg thiab teeb pom kev thoob ntiaj teb.Peb xav kom peb cov neeg ua haujlwm paub txog kev cia siab rau tus kheej, tom qab ntawd ua tiav kev ywj pheej nyiaj txiag, thaum kawg tau txais lub sijhawm thiab kev ywj pheej ntawm sab ntsuj plig.Peb tsis tsom mus rau ntau npaum li cas cov hmoov zoo peb tuaj yeem ua tau, hloov peb lub hom phiaj kom tau txais lub koob npe nrov thiab raug lees paub rau peb cov khoom.Yog li ntawd, peb txoj kev zoo siab yog los ntawm peb cov neeg siv khoom txaus siab ntau dua li peb khwv tau nyiaj ntau npaum li cas.Peb pab neeg yuav ua qhov zoo tshaj plaws rau koj ib txwm.
