Detailed explanation of S235JR steel plate

S235JR steel plate, a hot-rolled structural steel plate in the European standard, is generally delivered in the hot-rolled heat treatment state and is a grade that complies with European standards, with good machinability.

Chemical composition of S235JR steel plate:
Carbon C: ≤ 0.20;
Silicon Si: ≤ 0.50;
Manganese Mn: ≤ 1.40;
Sulfur S: ≤ 0.035;
Phosphorus P: ≤ 0.035;
Nitrogen N: ≤ 0.012;
Copper Cu: ≤ 0.55;
The chemical composition of each steel plate is different, so it is a maximum value as the standard, and the specific content is reflected in the quality assurance certificate.

Mechanical properties of S235JR steel plate:
S235JR yield strength（ σs/MPa）：≧235；
S235JR tensile strength（ σb/MPa）：360-510；
S235JR elongation after fracture（ δ5/%）：≧17；
S235JR impact energy Akv 20 degrees: ≥ 27 J.

Executive standards for S235JR steel plate:
S235JR steel plate is a European standard brand and also implements European technical standards. Currently, the latest standard EN10025-2-2019 is being implemented, and the previous EN10025-2-2004 has been replaced.

Delivery status of S235JR steel plate:
Generally, the delivery is made in the hot rolled heat treatment process state. If required, the normalized heat treatment process state can also be used for delivery. The specific delivery state depends on the customer's requirements, and if not required, it shall be reflected in the quality assurance certificate.
