ASTM A653 SS Qib 340 Chav Kawm 1 ASTM A653 / A653M Mechanical Properties
Yield zog yog qhov kev txwv ntawm ASTM A653 SS Qib 340 Chav Kawm 1 ASTM A653 / A653M thaum yielding tshwm sim, uas yog, kev ntxhov siab tiv thaiv micro-yas deformation. Lub zog sab nraud ntau dua li lub zog tawm los yuav ua rau ASTM A653 SS Qib 340 Chav Kawm 1 ASTM A653 / A653M qhov chaw mus tas li thiab tsis tuaj yeem rov qab tau. Tsawg dua qhov no, ASTM A653 SS Qib 340 Chav Kawm 1 ASTM A653 / A653M qhov chaw yuav rov qab los rau lawv cov qauv qub.
Lub zog tensile yog qhov tseem ceeb ntawm kev hloov pauv ntawm cov yas deformation mus rau hauv zos concentrated yas deformation. Nws tseem yog qhov siab tshaj plaws thauj khoom nqa ntawm ASTM A653 SS Qib 340 Chav Kawm 1 ASTM A653 / A653M nyob rau hauv qhov nro zoo li qub. Lub zog tensile yog qhov tsis kam uas ua rau lub siab tshaj plaws ntawm cov yas deformation ntawm ASTM A653 SS Qib 340 Chav Kawm 1 ASTM A653 / A653M. Lub deformation ntawm tensile specimens yog ib yam ua ntej lawv dais lub siab tshaj plaws tensile kev nyuaj siab, tab sis tshaj li ntawd, ASTM A653 SS Qib 340 Chav Kawm 1 ASTM A653 / A653M pib caj dab, piv txwv li concentrate deformation.
