S355J2W European standard weathering steel, S355J2WP corresponding material, S355J2W chemical compos

S355J2W is a weathering steel produced according to the European standard EN10025 standard, with a production thickness of less than 100mm, delivered in a hot-rolled state, with high fatigue resistance and atmospheric corrosion resistance.

S355J2WP steel plate fixed rolling: Wugang Xiangyang

European standard EN10025-5 name includes: S235JOW S235J2W S355J0WP S355J2WP S355J0WS355J2W S355K2W

The grade of S355J2W indicates: "S": indicates structural steel; "355" has a yield strength of 355, expressed in units MPa; "J2": impact energy level, -20° impact energy value 27J "W": indicates the weather resistance of the steel plate.

S355J2W and S355J2WP Introduction

S355J2W belongs to fine-grained steel, S3552W is an improved atmospheric corrosion resistant structural steel, which S355J2W widely used in high-speed rail bogies, welding, bolting and riveting parts, S355J2W enhance the ability to resist atmospheric corrosion at ambient temperature, in order to achieve the characteristics of corrosion resistance and add some specific alloying elements, such as: P, Cu, Cr, Ni, Mo, etc., to form a protective oxide layer on the metal surface under various climatic conditions.

S235JOW, S2352W, S355JOWP, S355J2WP, S355J0w, S355J2w, S355K2W are mainly divided into these categories. When the steel plate is marked "+N or +AR", the product is subject to mandatory regulations and delivery status under the condition of + or +AR.

The logo "+N or +AR" will be added to the steel name and steel number. For example, improved atmospheric corrosion resistant structural steel (S) with a minimum yield strength of 355 MPa and a minimum impact energy of 27 J joules (JO) and standard rolling delivery conditions in the environment: steel plate EN10025-5-S355J0W+N; or steel plate EN10025-5-1.8959+N (or +AR).
