P265GH Siab Vessel Steel Phaj

P265GH Hlau - Kub Resistant & Non-Alloy

P265GH yog dab tsi?
Qib P265GH yog cov cua kub uas tiv taus siab siab Vessel Steels tau teev tseg hauv EN 10028 system. Nws yog cov hlau tsis muaj hlau. Cov khoom siv yog tsim los rau kev siv kub. Yog li ntawd nws yog feem ntau siv nyob rau hauv high kub daim ntaub ntawv nyob rau hauv cov roj thiab roj sector, chemical processing industries thiab petrochemical sectors.

Nws yog ib qho tseem ceeb fabricating khoom ntawm boilers thiab pressurized hlab ntsha. Nws yog normalized los ntawm kev ua kom nws tiv thaiv qhov kub ntawm 890 txog 950 ° C yam tsis muaj tuav; cua sov yog dhau los ntawm lub thickness ntawm lub phaj.

EN 10028 yog dab tsi?
P265GH raug txheeb xyuas nyob rau hauv tus qauv EN 10028. Ntxiv mus, tus qauv npog "Non-alloy thiab alloy steels uas tau teev cov khoom kub siab". Tus qauv tau luam tawm xyoo 2009.

Vim li cas P265GH hu ua A516 qib 60 Steel?
P265GH yog lub npe alloy hauv European tus qauv, kuj hu ua A516 qib 60 hauv ASME / ASTM cov qauv. Ntau lub tuam txhab thov kom ua raws li ob qho kev qhia tshwj xeeb ntawm EN 10028 thiab ASME / ASTM cov khoom A516 qib 60 steel.
