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. State of the art
- 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 balance being Fe and accidental impurities, and wherein the sum of the Al and Si levels is higher than about 0.85wt% .
- 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%) :
- This embodiment combines good weathering behaviour in saline conditions with excellent mechanical properties, due to the minimum amounts of the abovenamed elements (Cu, Ti, Cr, Ni, Nb) .
- the present invention reveals that the inventive steel compositions favour the formation of fine grained goethite (a-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.
- a-FeOOH fine grained goethite
- x fine grained goethite' is meant goethite with grain sizes from about 8nm to about 15nm.
- 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 SI to S3 having Al and Si contents according to the invention, as well as 2 comparative samples CI and C2 having Al and Si contents falling outside the claimed ranges and/or wherein the combined Al and Si content is less than 0.85wt%.
- 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 Mossbauer 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 15nm, as opposed to antiferromagnetic goethite, having particle sizes above 15nm.
- 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.
