EN X10CrWMoVNb9 Details

Boiler tubes are used in heat exchange appliances in which the energy is transferred from one medium to the other. The pipes are manufactured from carbon and low-alloy steel grades which are resistant to loads under high pressure and temperatures. They are used for the construction of power engineering appliances such as: boilers, heating coils, stoves, heaters, heat exchangers.
