JIS G3456 STPT480 carbon steel yeeb nkabFeem ntau yog siv nyob rau hauv qhov kub thiab txias ib puag ncig nrog kub tshaj 350 degree. Qhov loj tshaj plaws ntawm cov yeeb nkab steel no yog tias nws yog tsim los siv cov txheej txheem seamless, yog li nws muaj lub zog siab thiab zoo heev los tiv thaiv corrosion, thiab tuaj yeem ua haujlwm ruaj khov nyob rau hauv high-pressure thiab high-temperature ib puag ncig.
STPT 480 carbon steel yeeb nkab yog qib carbon steel yeeb nkab siv rau kev siv kub. Qhov tsawg kawg nkaus tensile lub zog yog 480 MPa thiab qhov tsawg kawg nkaus yield zog yog 315 MPa. Cov kav dej no feem ntau siv hauv cov kav dej, boilers thiab cov hlab ntsha siab.
Nyob rau tib lub sijhawm, vim nws cov qauv seamless, cov yeeb nkab steel zoo li no muaj cov kua dej me me thiab kev ua haujlwm zoo, uas tuaj yeem txo qhov siab poob ntawm cov dej hauv cov kav dej. Yog li, JIS G3456 STPT
480 high-pressure carbon steel kav yog siv dav hauv roj av, tshuaj lom neeg kev lag luam, hluav taws xob fais fab thiab lwm yam kev lag luam.
