P355NH klas asye se youn nan klas nan EN10028-3, ki se ki pa alyaj ak asye alyaj ak espesifye pwopriyete tanperati ki wo. P355NH klas yo te itilize pi wo a tout pou fabrikasyon chodyèr, veso presyon ak tiyo transpòte likid cho.
Along with the P355NH steel plate, there are other boiler steels under EN10028-3, including P275NH boiler steel, P275NL1 steel, P275NL2 material, P355N boiler steel, P355NL1 boiler steel, P355NL2 steel, P460NH boiler steel, P460NL1 boiler steel, P460NL2 boiler steel.
Dapre anviwònman tanperati a, klasifikasyon an nan EN10028-3 veso asye se jan sa a:
Nòmal tanperati veso asye Klas: P355N plak asye.
Klas asye nan gwo tanperati ki reziste veso: P355NH plak asye.
Klas bon jan kalite tanperati ki ba: P355NL1 Steel, P460NL1 plak asye.
Espesyal ki ba bon jan kalite klas klas: P355NL2 plak asye, p460NL2 plak asye.
