P355NH Siab Vessel Steel
P355NH boiler steel phaj yog lub siab-lub zog qis-alloy steel phaj tsim rau cov hlab ntsha siab, uas ua raws li European tus qauv EN 10028-3.
P355NH nkoj phaj muaj kev tiv thaiv corrosion zoo heev, hnav tsis kam, qaug zog thiab lwm yam ntxwv tom qab kev kho tshwj xeeb, thiab tuaj yeem ua haujlwm ruaj khov hauv qhov chaw ua haujlwm hnyav.
P355NH boiler steel phaj yog siv nyob rau hauv zus tau tej cov reactors, tshav kub exchangers, separators thiab lwm yam khoom siv siab bearing nyob rau hauv cov roj av thiab tshuaj industries, thiab muaj peev xwm tiv taus siab thiab corrosive ib puag ncig.
