Hot rolled steels for one-side enamelling are steels with a specific chemical composition, which can guarantee:
Two grades are available to match the requirements of different applications: S240EK AM FCE and S300EK AM FCE, which can be supplied pickled or unpickled and oiled or unoiled.
Grades S240EK AM FCE and S300EK AM FCE are used to manufacture water heater tanks with very good mechanical strength and good resistance to in-service stresses. In addition, by using these grades, and S300EK AM FCE in particular, the thickness of the steel can be reduced.
After enamelling, the inside wall of the tank has excellent corrosion, heat and moisture resistance.
Hot rolled steels for one-side enamelling are mainly intended for the manufacture of tanks for water heaters. They can also be used for enamelled tubes or coiled pipes.
Forming of hot rolled grades for one-side enamelling presents no particular problems:
All the usual welding processes can be used (TIG, MIG, seam welding, laser).
Surface preparation and enamelling of water heaters
The surface must be treated by pickling or shot blasting.
Enamel can be applied in a wet or dry process.
Firing is performed at a temperature of about 830°C.
Conservation of mechanical properties after enamelling
The mechanical properties of hot rolled steel for one-side enamelling remain unchanged after forming and firing of the enamel. This offers the following advantages:
