If S355J2WP 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.
s355j2wp vs s355j0wp
S355J2WP vs. S355J0WP are both atmospheric corrosion-resistant (weathering) steels under EN 10025-5, but the key difference lies in their chemical composition, specifically Phosphorus (P) content, with S355J2WP generally having higher P for enhanced corrosion resistance, while J0 has lower P, with both meeting similar strength (355 MPa yield) and impact toughness requirements (J0 is 0°C, J2 is -20°C), though 'W' signifies weathering properties and 'P' denotes added phosphorus for better rust patina formation.
Here's a breakdown:
S355: Minimum yield strength of 355 MPa (for thicknesses up to 16mm).
J0 / J2: Indicates toughness level; J0 requires impact energy at 0°C, J2 at -20°C (J2 is tougher).
W: Means it's a weathering steel with improved atmospheric corrosion resistance (Corten steel).
P: Signifies added Phosphorus (P) for superior rust patina, making it more weather-resistant than grades without the 'P' (like S355J2W).
Key Differences:
S355J0WP: Contains less Phosphorus (P), relies more on Cu, Cr, Ni for corrosion resistance, often delivered normalized.
S355J2WP: Contains higher Phosphorus (P) content, which significantly boosts its self-protective patina formation, offering superior corrosion resistance for outdoor applications.
Below are the their comparison of chemical composition, mechanical properties and impact test strength.
