Definitions

  • the present invention is related to steel types and products made thereof, which exhibit an increase in corrosion resistance when exposed to a chlorine-rich environment. These steels are known as weathering steels.
  • JP2006118011 in the form of a steel composition comprising C, Al, Si, P, Ni, Cu, N, with Sn and/or Sb added in an amount between 0.03 and 0.5 wt % and one or more of Ti, Nb, Mo, W, V, Ca or Mg, with the mass ratio of Ni/Cu smaller than or equal to 0.5.
  • the weathering capability in saline environment is mainly obtained by the presence of Sb and/or Sn, which stabilize the amount of Fe2+ ions when the steel is in a wet and saline environment, by reacting with Fe3+ ions, produced by oxidation of Fe2+.
  • Sn and/or Sb is disadvantageous for various reasons :
  • the present invention aims to provide a weathering steel with a Ni-content in the same order of magnitude as in traditional weathering steels, and with an increased corrosion resistance in marine or seaside conditions, as well as with excellent mechanical properties.
  • the invention is related to a steel product as disclosed in the appended claims.
  • the invention is in particular related to a steel product as disclosed in the main independent claim, suitable for use in outdoor environments, in particular in saline conditions.
  • the steel product of the invention may be any type of construction element such as a steel sheet or beam.
  • the invention is related to a steel composition characterized by the following contents (in wt %):
  • the following narrower ranges are defined for Cu, Ti, Cr, Ni and Nb (in wt %):
  • the steel product according to the invention comprises no Sn and no Sb.
  • the present invention is related to a steel product of the weathering steel type, i.e. a product exhibiting increased corrosion resistance after having been exposed to the outside environment for a given time.
  • the steel product is defined by a composition consisting of (in wt %):
  • the amounts of Cu, Ti, Cr, Ni and Nb are as follows (in wt %):
  • the present invention reveals that the inventive steel compositions favour the formation of fine grained goethite ( ⁇ -FeOOH) in the corrosion layer forming on the surface of a steel product having these compositions, due to the specific combined Al and Si content.
  • fine grained goethite is meant goethite with grain sizes from about 8 nm to about 15 nm. The formation of such fine grained goethite is beneficial for the stability of the oxide layer in saline conditions.
  • inventive compositions do not necessarily include an addition of significant amounts of the traditional elements regarded as beneficial for weathering resistance in saline conditions, such as Ni.
  • inventive compositions do not comprise Sn and Sb above an accidental impurity level.
  • the steel product of the invention comprises no Sb or Sn.
  • Elements such as Nb, Ti, Cu, Cr may be added for improving the mechanical properties of the steel, but are not required for ensuring the weathering behaviour in saline conditions.
  • the invention is related to any type of steel product having the composition as claimed, e.g. steel sheets or beams, obtained by any standard steel-making process, e.g. hot-rolled or cold-rolled sheets or beams.
  • Table 1 shows the compositions of 3 test samples S1 to S3 having Al and Si contents according to the invention, as well as 2 comparative samples C1 and C2 having Al and Si contents falling outside the claimed ranges and/or wherein the combined Al and Si content is less than 0.85 wt %.
  • test samples have been obtained by standard steel processing methods, involving at least a hot rolling step, possibly followed by a cold rolling step.
  • the samples were subjected to a dip-dry test during 60 days, using a 0.05M NaCl solution, in order to test weatherability behaviour in saline conditions.
  • oxide layers were formed on the samples.
  • the composition of these oxide layers was investigated by Mössbauer spectroscopy, used in particular to measure the relative area of superparamagnetic goethite in the oxide layer.
  • Superparamagnetic goethite has a particle size between 8 and 15 nm, as opposed to antiferromagnetic goethite, having particle sizes above 15 nm.
  • Table 2 clearly shows that the combined Al and Si contents according to the present invention give rise to a considerable increase in the relative area of fine-grained goethite in the oxide layer.
