CM690 qib, Dab tsi yog Cov Tshuaj Muaj Zog ntawm GB CM690 GB / T 18669? Chemical Composition ntawm CM690 Steel, CM690 steel zog, CM690 carbon hlau, GB steel phaj tsum nyob rau hauv Nyiv, GB steel ntawv Exporter, GB steel nqe, GB sib npaug steel, GB steel tsum nyob rau hauv Tuam Tshoj, GB steel Suav sib npaug qib, GB CM690 GB /T 18669 steel specifications

Lub zog tawm los yog qhov kev txwv ntawm GB CM690 GB / T 18669 thaum yielding tshwm sim, uas yog, kev ntxhov siab tiv thaiv micro-plastic deformation. Lub zog sab nraud ntau dua li lub zog tawm los yuav ua rau GB CM690 GB / T 18669 qhov chaw tsis ua haujlwm thiab tsis tuaj yeem rov qab los. Tsawg dua qhov no, GB CM690 GB/T 18669 qhov yuav rov qab mus rau lawv qhov qub.
Lub zog tensile yog qhov tseem ceeb ntawm kev hloov pauv ntawm cov yas deformation mus rau hauv zos concentrated yas deformation. Nws kuj tseem yog qhov siab tshaj plaws thauj khoom muaj peev xwm ntawm GB CM690 GB / T 18669 nyob rau hauv qhov nro zoo li qub. Lub zog tensile yog qhov kev ua haujlwm uas ua rau lub siab tshaj plaws ntawm cov yas deformation ntawm GB CM690 GB / T 18669. Lub deformation ntawm tensile specimens yog uniform ua ntej lawv dais siab tshaj tensile kev nyuaj siab, tab sis tshaj li ntawd, lub GB CM690 GB / T 18669 pib caj dab, i.e. concentrate deformation.
