S235JR steel plate: Chemical composition and Application
What is S235JR steel plate
Steel grade S235JR is a popular general construction and machine steel that is made in accordance with the EN 10025-2 standard.
S235JR describes non-alloy structural steels and falls in Part 2 of the EN 10025 specification. The S denotes a structural steel with a yield strength of 235 MPa. The JR designation confirms that the material has undergone a Charpy V-notch impact test at 27 joules at room temperature.
