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.

a) FN= Not allowed effervescent steel; FF= Completely calm steel.

b) For long products the content of P and S could be a 0,005% superior.

c) The steels should contain, at least, one of the following elements: Total ≥ 0,020%; Nb: 0,015%-0,060%; V:0,02%-0,12%; Ti: 0,02%-0,10%. If these elements are used combined, at least, one of them must be present in the minimum amount mention.

d) Shall be permitted to exceed the specified values on condition that for each increase of 0,001% of N, the maximum content of P Is reduced in 0,005%; anyway, the N quantity of the trial analysis should not exceed 0,012%.

e) The steels can present a maximum Ni content of 0,65%

f) The steels can present a maximum Mo content of the 0,30% and Zr content of 0,15%.

g) The maximum nitrogen value is not applied if the Al content is at very least of 0,020% or when there are other fasteners of N in sufficient content. In this case the N fasteners should be indicated in the inspection document.

a) For sheets, sashes and width plans with width ≥ 600mm we apply the transversal direction in the sense of lamination. For the other products, the values are applied in the parallel direction of the lamination.

b) 1MPa = 1 N/mm2.

c)

  • For flat products: apply until 12mm.
  • For long products: apply until 40mm.

HIGH TEMPERATURE RESISTANCE:

Additionally, this steel has more resistance to high temperatures than ordinary steel.
