Characteristics
By the chemical composition, after a certain period it forms a self-defense layer in the surface that stops the corrosion progress in industrial or urban ambience. In marine environments the corrosion attack is slower than in the rest of carbon steel. On average, the resistance to the atmospheric corrosion is four times superior to the ordinary steel, presenting A quality a behavior greater than B quality.
When the abrasion is in damp environment, its behavior is far superior to other steels of the same resistance.
The self-defense layer gives a very usable aspect of decoration, facades or roofs uncoated. By persisting with its characteristics during a long time it does not require maintenance. In thickness less to 5mm, it is advisable to superficially protect the sheets, without warranting the behavior of the steel when it is used directly against to the atmospheric agents.
Typical applications
Cement industry, silos, hoppers, screening machine, pipes, coal washeries, water storages, petrol, and fuel-oil. Metallic buildings, bridges, structures, façade of buildings, metallic door.
Mixers, cranes, scoops. Railway wagons, truck chassis, tilting, cisterns, semitrailers.
Soldering/Welding
Good for any of the procedures of structural steels. To make the welding cord also resistance to the corrosion, It should be used a filler material with a content of 2,5% of Ni with an approximated or similar composition of the base metal. In a weak and medium thickness it can be used OERLIKON type TENCOR-TI electrodes, as OK7308.
