Flaw Detection of S235JR steel plate

In the previous article, we wrote about the hot rolling of S235JR steel plates. This article will analyze the flaw detection of S235JR steel plates.

The flaw detection of S235JR steel plate should be carried out according to the European standard and the German flaw detection standard, or according to the flaw detection standard of national standard.

For flaw detection, national standard requires more strictly than the German and the European standard. So, the last two standards are commonly used for the flaw detection of S235JR steel plate with a thickness above 200mm. Thickness exceeding the testing range is considered as unqualified in the national standard , so we generally use the German standard for thick plates.
