Kub Muag rau Carbon Steel Alloy ASTM A508-98 40mn2 / 45mn2 / 27simn / 20cr / 40cr Seamless Steel Pipe Ua nyob rau hauv Suav teb
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 luag haujlwm yog ib txwm muab peb cov neeg siv khoom thiab cov neeg siv khoom zoo tshaj plaws thiab cov khoom lag luam zoo tshaj plaws rau Kev Muag Khoom Kub Kub rau Carbon Steel Alloy ASTM A508-98 40mn2 / 45mn2 / 27simn / 20cr / 40cr Seamless Steel Pipe Ua nyob rau hauv Suav teb, Peb yuav muab siab- cov khoom zoo thiab cov kev pabcuam zoo heev ntawm tus nqi sib tw.Pib tau txais txiaj ntsig los ntawm peb cov kev pabcuam dav dav los ntawm kev tiv tauj peb hnub no.
