S355J0WP Mechanical Property,S355J0WP Chemical Composition

S355J0WP steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance. S355J0WP steel plate is for low alloy structural steel with 355Mpa minimum yield point to 16mm thickness. When usually exposed to the atmosphere, S355J0WP is suitable for many applications in the bare condition.

S355J0WP Mechanical Property

S355J0WP Thickness(mm) MinYield(Mpa) Tensile(MPa) Elongation (%) Min Impact Energy
S355J0WP ≤16mm Min 355Mpa 470-630Mpa 22 0 27J
16-40mm Min 345Mpa 470-630Mpa 22 0 27J
The min impact energy is longitudinal energy

If S355J0WP 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.

S355J0WP Available size:
Thickness: 1mm-300mm
With: 1000mm-4000mm
Length: 2000mm-18000mm

S355J0WP Supplementary requirements:
Z15, Z25, Z35 test;
Charpy V impact test;
Ultrasonic test, A578 Level A, B, C, A435;
PWHT test.
