P355NhlH tus qauv hlau yog ib qib hauv EN10028-3, uas tsis muaj almoy thiab alloy steels nrog cov khoom siv kub thiab ntsuas. P355NH cov qib kawm tau siv saum toj no txhua yam rau kev tsim khoom siv boilers, siab cov hlab ntsha thiab cov kav dej thauj cov kua kub.
Nrog rau p355nH steel phaj, muaj lwm cov boiler class nyob rau hauv ENOLSEX, P355NL2 Cov Hlau Boiler, P455NL1 Boiler, P460NL2 Boiler Hlau.
Raws li qhov kub ib puag ncig, kev faib tawm ntawm EN10028-3 lub nkoj hlau yog raws li hauv qab no:
Cov Hluav Taws Xob Kub Qub Hluav Taws Xob Hlau Qib: P355N Hlau Phaj.
Qeb Qib Hlau Txheej Kub Kub Resistant Txog ntsha: P355NHir Phaj.
Tsawg qhov kub tau zoo qib: P355NL1 hlau, P460NL1 Steel phaj.
Tshwj xeeb tsawg kawg yog qib: P355NL2 steel hlau phaj, P460NL2 Hlau Phaj.
