27SiMn Kub Rolled Seamless Steel Tube 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.
Kev ntseeg siab zoo tshaj plaws thiab cov qhab nia zoo tshaj plaws yog peb cov hauv paus ntsiab lus, uas yuav pab tau peb ntawm txoj haujlwm saum toj kawg nkaus.Adhering ntawm lub tenet ntawm "zoo ua ntej, cov neeg siv khoom zoo tshaj plaws" rau 27SiMn Kub Rolled Seamless Steel Tube Alloy Seamless Steel Yeeb Nkab, Txij li thaum lub chaw tsim khoom tsim, peb tau cog lus rau kev nce qib ntawm cov khoom tshiab.Nrog rau kev sib raug zoo thiab kev lag luam pace, peb yuav txuas ntxiv mus rau pem hauv ntej tus ntsuj plig ntawm "zoo heev, ua haujlwm zoo, kev tsim kho tshiab, kev ncaj ncees", thiab nyob nrog lub hauv paus ntsiab lus ntawm kev khiav hauj lwm ntawm "credit thawj zaug, cov neeg siv khoom 1, cov khoom zoo heev".Peb yuav tsim lub neej yav tom ntej zoo tshaj plaws hauv cov plaub hau tso zis nrog peb tus khub.
