S355J0WP Steel Grade, Mechanical Properties, Chemical Composition, Grade Equivalent

Standard: EN 10025-5 :2004 European standard for hot-rolled structural steel. Part 5 - structural steels with improved atmospheric corrosion resistance - technical delivery conditions.

Steel grade: S355J0WP ;

Number: 1.8945 .

Steels with improved atmospheric corrosion resistance have a wide range of applications: architecture, smokestacks, freight wagons, silos, pylons and bridges.

Weldability: If filler metal without improved atmospheric corrosion resistance is used ensure that the weld itself is weather resistant. Before welding, any surface layer which has already been formed should be removed to a distance of 10 mm to 20 mm from the joint edges. Special precautions should be taken when welding steel grades S355J0WP and S355J2WP with a high phosphorus content. General requirements for arc welding of the steels specified in this document are given in EN 1011-2.

The table below show the chemical composition of grade S355J0WP
Ladle analysis.
For long products the P and S content can be 0,005 % higher.
The steels shall contain at least one of the following elements: Al total ≥ 0,020 %, Nb: 0,010 - 0,065 %, V: 0,01 - 0,14 %, Ti: 0,01 - 0,12 %. If these elements are used in combination, at least one of them shall be present with the minimum content indicated.
The steels may show a Ni content of max. 0,70 %.
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.
