E36WA4 Steel Description:
E36WA4 steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.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.
E36WA4 steel is the Equivalent grades as S355J2WP (1.8946) steel in EN 10025 - 5 : 2004 standard and FE510D1K1 steel in UNI standard and also A242 Type1 steel in ASTM standard.
E36WA4 Steel Delivery state:
Hot Rolled, Cold Rolled, Normalized, Quenched, Tempering, Thermal Mechanical Control Process (TMCP), Electroslag Remelting Technical, HIC test.
E36WA4 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 0.03
Cu %	P %
0.25-0.55	0.06 - 0.15

Method of deoxidation FF = fully killed steel

For long products the P and S content can be 0.005% higher
The E36WA4 steels may show a Ni content of max. 0,65 %

The E36WA4 steels shall contain at least one of the following elements: Al total ≥ 0,020 %, Nb: 0,015 - 0,060 %, V: 0,02 - 0,12 %, Ti: 0,02 - 0,10 %. If these elements are used in combination, at least one of them shall be present with the minimum content indicated.

E36WA4 steel mechanical property

Grade	Min. Yield Strength Mpa						Tensile Strength MPa			Impact
E36WA4	Nominal Thickness (mm)						Nominal Thickness (mm)			degree	J
Thick mm	≤16	>16 ≤40	>40 ≤63	>63 ≤80	>80 ≤100	>100 ≤150	≤3	>3 ≤100	>100 ≤150	-20	27

If E36WA4 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. 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.
