27SiMn Kub Rolled Hydraulic Prop Tube 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.
Peb lub hom phiaj kom paub qhov zoo tshaj plaws disfigurement nyob rau hauv lub tiam thiab muab cov kev pab cuam zoo tshaj plaws rau domestic thiab txawv teb chaws cov neeg siv tag nrho lub siab dawb paug rau 27SiMn Kub Rolled Hydraulic Prop Tube Seamless Steel Yeeb Nkab, peb cov khoom muaj superior muaj koob meej ntawm lub ntiaj teb no raws li nws feem ntau competive tus nqi thiab peb feem ntau. qhov zoo ntawm kev pab cuam tom qab muag rau cov neeg siv khoom.
Peb tsom mus nrhiav kom paub qhov zoo tshaj plaws disfigurement nyob rau hauv tiam thiab muab cov kev pab cuam zoo tshaj plaws rau cov neeg siv khoom hauv tsev thiab txawv teb chaws lub siab dawb paug rauTuam Tshoj 27SiMn Alloy Seamless Steel Yeeb Nkab, Peb tau mob siab rau kev lag luam tseem ceeb "Quality First, Honoring Contracts and Standing by Reputations, muab cov neeg siv khoom txaus siab rau cov khoom muag thiab kev pabcuam.” Cov phooj ywg nyob hauv tsev thiab txawv teb chaws zoo siab txais tos los tsim kev lag luam mus ib txhis nrog peb.
