S235J2 Chemical composition (%)
| composition | C ① | Mn | P ② | S ②③ | Cu ④ | More |
|---|---|---|---|---|---|---|
| Min | - | - | - | - | - | ⑤ |
| Max | 0.17 | 1.4 | 0.025 | 0.025 | 0.55 |
① For profiles with nominal thickness >100mm, C content is negotiated.
② For long products, P and S contents are 0.005% or higher.
③ For long products, if the form of sulphide in steel is changed, the maximum value of S content is increased by 0.015% in order to improve the mechanical properties, and the chemical composition is the minimum value of 0.0020% Ca.
④ Cu content can cause thermal embrittlement during thermoforming if it exceeds 0.40%.
⑤ If other elements are added, they should be reflected in the inspection documents.
