Q235 Carbon Steel Plate

Q235 steel is the most common low-carbon steel, and there are many equivalent steel grades in other countries. For example, the European standard is EN10025-2 S235JR; the Japanese standard is JIS G3101 SS400, the German standard is DIN17100 ST37-2, and the American standard is ASTM A36. The mechanical properties of these grades are similar, but there are slight differences depending on regional standards.

Chemical Composition

According to the GB/T 700-2006 standard, carbon structural steel Q235 is classified into four categories based on metallurgical quality: A, B, C, and D. The chemical makeup of Q235A, B, C, and D differs. The sulfur concentration of A, B, C, and D declines sequentially, while the phosphorus content of A and B is the same, followed by that of C, and the phosphorus level of D is the lowest.

Mechanical Properties

Different grades of Q235A, Q235B, Q235C, and Q235D correspond to different impact temperatures. A indicates no influence, B is greater than 20 degrees, C is greater than 0 degrees, and D is greater than -20 degrees.

Product Parameters

Application fields
