Chaw tsim khoom txheem 27SiMn Alloy Seamless Steel Yeeb Nkab
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.
Txhawm rau tsim kom muaj txiaj ntsig ntau dua rau cov neeg siv khoom yog peb lub tuam txhab lub tswv yim;cov neeg siv khoom loj hlob yog peb txoj haujlwm ua haujlwm rau cov qauv tsim 27SiMn Alloy Seamless Steel Yeeb Nkab, Peb tab tom nrhiav ua ntej los koom tes nrog txhua tus neeg yuav khoom los ntawm koj lub tsev thiab txawv teb chaws.Ntxiv mus, kev txaus siab ntawm cov neeg siv khoom yog peb txoj kev nrhiav mus ib txhis.
