ASTM A53 Resistance Welded Yeeb Nkab Raw Khoom

Hlau siv los tsim ASTM A53 steel yeeb nkab (xws li seamless thiab welded yeeb nkab) yuav tsum tau tsim siv cov txheej txheem hauv qab no: qhib-hearth hluav taws xob rauv lossis cov pa oxygen converter.

Cov qib sib txawv ntawm cov hlau yog tsim los ntawm kev sib cais ndlwg casting, yuav tsum tau txheeb xyuas cov khoom hloov pauv. Cov neeg tsim khoom yuav tsum tshem tawm cov khoom hloov pauv uas siv cov txheej txheem tsim kom pom tseeb qhov txawv ntawm cov qib sib txawv.

Yog li ntawd, tsis muaj martensite untempered yuav tsum nyob twj ywm nyob rau hauv weld, los yog lwm yam untempered martensite yuav tsum tau muab tshem tawm los ntawm lwm txoj kev.

Yog tias cov yeeb nkab txias -flated, qhov flaring npaum li cas yuav tsum tsis pub tshaj 1.5% ntawm txoj kab uas hla.

Hais txog peb lub tuam txhab
