How does EN 10025-5 S355J0WP Corten steel play its role of the anti-corrosion?

 EN 10025-5 S355J0WP Corten steel has main alloying elements are chromium, nickel and copper with added phosphorous, which gives it awesome self-protection qualities. Besides, S355J0W steel offers excellent, cost effective protection against atmospheric conditions without the need for painting or external treatment.

EN S355J0W Chemical Composition

Grade	C	Si	Mn	P	S	V	Cu	Cr
S355J0W	Max0.16	0.50	0.5-1.5	0.035	0.035	0.009	0.25-0.55	0.4-0.8

EN S355J0W Mechanical Properties

Grade	Yield strength	Tensile strength	Elongation
S355J0W	Min295-355MPa	Min 450-680	16-17

How S355J0WP Corten Steel Resistant Rusting:

S355J0WP resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions. The surface of the metal S355J0WP can form a coating of dark brown oxidation, which inhibits deeper penetration, so S355J0WP steel save the cost of need for painting.

Application of EN S355J0W

S355J0WP steel is widely used for bolted and riveted constructions such as steel frame structures, bridges, tanks and containers, exhaust systems, vehicles and equipment constructions and so on.
