ASTM Carbon Kub Rolled Seamless Steel Pipes St52 Honed Tube Lub tog raj kheej
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.
Persisting nyob rau hauv "High zoo, sai xa tuaj, Aggressive nqi", peb tau tsim kev koom tes ntev nrog cov neeg siv khoom los ntawm ob qho tib si txawv teb chaws thiab domestically thiab tau txais cov neeg tshiab thiab qub cov lus siab dua rau St52 Yeeb Nkab Tubes St52 Honed Tube Lub tog raj kheej ASTM Carbon Kub Rolled Seamless Steel Pipes, Peb tsuas yog tsis tsuas yog muab cov khoom zoo rau peb cov neeg siv khoom, tab sis qhov tseem ceeb tshaj yog peb cov kev txhawb nqa loj tshaj nrog rau cov nqi sib tw.
Persisting nyob rau hauv "High quality, Prompt Delivery, Aggressive Price", peb tau tsim kev koom tes ntev nrog cov neeg siv khoom los ntawm ob qho tib si txawv teb chaws thiab domestically thiab tau txais cov neeg tshiab thiab qub cov lus siab dua rauTuam Tshoj Carbon Steel Seamless Yeeb thiab Seamless Carbon Steel Yeeb Nkab, Ntau yam khoom ua tau raws li qhov nruj tshaj plaws ntawm cov txheej txheem thoob ntiaj teb thiab nrog peb cov kev pabcuam xa khoom thawj zaug koj yuav tau xa lawv txhua lub sijhawm thiab nyob rau txhua qhov chaw.Thiab vim Kayo cuam tshuam rau tag nrho cov khoom siv tiv thaiv, peb cov neeg siv khoom tsis tas yuav nkim sijhawm mus ncig.
