JIS SPV 42 JIS G3115 Mechanical Properties
Muaj peb pawg tseem ceeb ntawm JIS SPV 42 JIS G3115 steel; steel phaj nrog lub zog tensile tsawg, cov uas muaj lub zog nruab nrab tensile thiab cov uas muaj zog tensile siab. Low-tensile steel phaj muaj lub zog tensile txog li 270MPa thiab feem ntau yog siv rau hauv kev tsim cov boilers, thawv-qhov, plhaub, thiab lub teeb hauv cheeb tsam ships. Medium-tensile steel daim hlau muaj lub zog tensile txog li 510MPa thiab feem ntau yog siv rau nruab nrab-siab cov hlab ntsha vim lawv cov qib siab toughness. High-tensile steel phaj muaj lub zog tensile txog li 760MPa thiab feem ntau yog siv rau hauv kev tsim cov hlab ntsha siab rau kev lag luam roj thiab roj thiab hauv cov nroj tsuag petrochemical.
Lub zog tawm los yog qhov txwv tsis pub dhau ntawm JIS SPV 42 JIS G3115 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 JIS SPV 42 JIS G3115 qhov chaw mus tas li thiab tsis tuaj yeem rov qab los. Tsawg dua qhov no, JIS SPV 42 JIS G3115 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 ntawm kev thauj khoom ntawm JIS SPV 42 JIS G3115 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 JIS SPV 42 JIS G3115. Lub deformation ntawm tensile specimens yog uniform ua ntej lawv dais lub siab tshaj plaws tensile kev nyuaj siab, tab sis tshaj li ntawd, lub JIS SPV 42 JIS G3115 pib caj dab, piv txwv li concentrate deformation.
