P460N Siab Vessel Steel Phaj

P460N steel qib yog ib qib nyob rau hauv En10028-3, uas tsis yog alloy thiab alloy steels uas tau teev cov khoom kub. P460N qib yog siv rau saum toj kawg nkaus rau kev tsim cov boilers, cov hlab ntsha siab thiab cov kav dej thauj cov kua kub.

EN10028 steel qib hloov pauv cov qauv qub BS thiab DIN.


Daim ntawv thov tseem ceeb:
EN10028-3 P460N Siab Vessel Thiab Boiler Steel Phaj yog siv rau hauv Lub Nkoj Siab, Boiler, Cia Tank thiab Kub Exchanger hauv Roj, Gas Project.
