• WR50A Steel Description

  WR50A is a structural weathering steel which is also referred to as atmospheric corrosion resistant steel. The main alloying elements are chromium nickel and copper with added phosphorous which gives it excellent self protecting qualities. As the steel reacts with elements in the atmosphere, the material forms a layer of rust over time which in essence protects the steel from corrosion.

  WR50A steel is the Equivalent grades as S355J0WP (1.8945) steel in EN 10025 - 5 : 2004 standard and FE510C1K1 steel in UNI standard and also E36WA3 steel in NFA 35-502 standard.

  Hot Rolled, Cold Rolled, Normalized, Quenched, Tempering, Thermal Mechanical Control Process (TMCP), Electroslag Remelting Technical, HIC test.

• WR50A steel application

  WR50A (which is an equivalent grade to Corten A) provides a long lasting and economic structural steel solution for use in applications such as steel bridges stack gas applications and in steel sculptured buildings due to the material's aesthetically pleasing finish. Moreover, WR50A steel with improved atmospheric corrosion resistance has a wide range of applications: architecture, smokestacks, fabrication, freight wagons, silos, pylons etc..

• WR50A steel chemical composition by [%]

   

  C %	Mn %	Cr %	Si %	CEV %	S %
  Max 0.12	Max 1	0.3-1.25	Max 0.75	Max 0.52	Max 0.035
  Cu %	P %	N %
  0.25-0.55	0.06 - 0.15	Max 0.009

  Method of deoxidation FN = rimming steels not permitted.
  CEV=
  For long products the P and S content can be 0.005% higher.
  The WR50A steels may show a Ni content of max. 0,65 %.
  The max. value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % or if sufficient other N binding elements are present. The N binding elements shall be mentioned in the inspection document

  The tensile test values given in the table apply to longitudinal samples; in case of strip and sheet steel of widths of ≥600 mm they apply to transverse samples.
  If WR50A mechanical properties have been significantly modified by heavy coldforming, either stress relief annealing or normalised may be applied. Normalised should also be applied following hotforming outside of the temperature range of 750 - 1.050 °C and after overheating.
