P460NH Siab Vessel Steel Phaj

P460NH, yog li hu ua kom muaj qhov tsawg kawg nkaus lub zog ntawm 460 MPa, yog lub siab zoo siab qib steel qib rau siv hauv boiler thiab siab hlab ntsha fabrication. Nws yog ib tug normalized zoo grain steel nrog zoo weldability yam ntxwv.

Lwm hom qib suav nrog…
NL1 - yog qhov zoo tagnrho rau siv hauv qhov kub thiab txias
NL2 - yog qhov zoo tagnrho rau kev siv tshwj xeeb hauv qhov kub thiab txias

P460NH kuj tseem siv rau hauv cov ntawv siv roj qaub uas cov hlau yuav raug HIC Tested los ntsuas cov ntaub ntawv raug rau hydrogen induced cracking.
