Boiler Steels
As it is understood from the name of boiler sheets, it is the type of steel plate used in boiler production. Boilers are generally used in the internal structure of boilers. Boiler sheets are pressure resistant steels. Commercial grade steels start with S quality designation, for example S235JR, and boiler sheets are P group steels. There are varieties according to different strength such as P235GH quality, P265GH quality, P355GH grades, 16MO3 Quality, P295GH Quality, P355NH Quality, P355NL1 Quality.
Quality boiler plates P235GH production serves only Erdemir in Turkey. P235GH Quality steel sheets Erdemir quality corresponds to 6335 quality. In the description of Erdemir 6335 quality steels, kazan Boiler steels suitable for use under high temperature and pressure “is written.
