S355J2 is a low carbon, high tensile strength structural steel which can be readily welded to other weldable steel. With its low carbon equivalent, it possesses good coldforming properties. The plate is produced by fully killed steel process and supplied in normalized or controlled rolling condition.
Conform specification EN 10025 S355J2 has a Charpy Value of min. 20J at -20C. What can I expect for the charpy value at -10C. For my design I need a min. value of 36J at -10C.
The Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material's notch toughness and acts as a tool to study temperature-dependent ductile-brittle transition.
S355J2+N and S355J2G3 are the same steel grades as both grades delivery condition are normalized. G3 and N stand for normalized. S symbol for Structural Steel. JR symbol 20 temperature impact test. J0 symbol 0 temperature impact test. J2 symbol -20 temperature impact test. S355 J2+N Steel Plate Grade and Specification

S355 structural grade (S) carries minimum yield strength of 355 N/mmm, the JR designation confirms that the steel has undergone longitudinal Chary V-Notch impact testing at 27J (Joules) at room temperature. Other Charpy designations include J0, J2 and K2.
