Where is the SA588 grade B carbon steel plate sheet BBN company

SA588 grade B carbon steel plate sheet, Q690CF steel plate, also known as CF (CrackFree) steel in the world, is a kind of steel with low carbon equivalent, low PCM value and excellent welding function. It is generally believed that there is no crack in welding without preheating or under low preheating conditions. In order to further improve Q690CF steel strength, TMCP and microalloying skills are also required.

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, SA588 grade B carbon steel plate sheet is of high quality? First of all, check whether there are cracks on the surface of the SA588 grade B carbon steel plate sheet 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.

Our company will accept the product quality objection registration record, pass it to the SA588 grade B carbon steel plate sheet production unit and relevant departments, and timely coordinate the supervision of product SA588 grade B carbon steel plate sheet quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
