Flaw detection of S690QL1 material

In the whole steel structure and steel body, the medium and heavy plate is an important part, once the problem occurs, it is easy to fracture, collapse and occur explosion. So how to judge whether the medium and heavy plate, S690QL1 material is of high quality? First of all, check whether there are cracks on the surface of the S690QL1 material plate and how glossy it is. Secondly, to measure the thickness error of medium and heavy plate, it is better to use the instrument to measure the bending tensile value. Finally, observe the scale of the steel plate manufacturers, whether there are relevant qualification certificates, and how the production process is.

Q245R boiler steel plate introduction: Q is the first letter of "Qu" Chinese Pinyin; Number 245 is the yield strength value; R: is the first character of "Rong" Chinese Pinyin. Q245R steel is a special plate for pressure vessels and boilers with a yield strength of 245MPa. It has outstanding mechanical properties and processability. If you have special requirements, our company can supply Z15, Z25, Z35 and other Z performance tests.

Quenching Improve the hardness of S690QL1 material steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress.
