E36WA3 Steel

E36WA3 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.
E36WA3 steel is the Equivalent grades as S355J0WP (1.8945) steel in EN 10025 - 5 : 2004 standard and WR50A steel in BS 4360 standard and also FE510C1K1 steel in UNI standard.

The specifications:
Thickness: 3mm--150mm
Width: 30mm--4000mm
Length: 1000mm--12000mm
Standard: ASTM EN10025 JIS GB

E36WA3 steel chemical composition

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
For long products the P and S content can be 0.005% higher.
The E36WA3 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 E36WA3 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.
