S355J2+N Q355ND steel plate comparative analysis in performance and application

S355J2+N steel plate is a grade of European standard alloy structural steel plate, which implements EN10025-2 technical standard;

While Q355NE steel plate is a steel grade of Chinese standard material, which is subject to GB1591-2018 technical conditions.

The impact temperature of S355J2+N steel plate and Q355ND steel plate is - 20 degrees below zero, and the delivery status of the steel plate is normalized - normalized rolling.

The difference lies in the composition and content of the chemical elements between the two, and the standard of the first level flaw detection is different.

S355J2+N steel plate and Q355ND steel plate are common steel plate grades, which are used in mechanical manufacturing and corresponding machining industries.
