Q390B鋼板的使用面積比較大，也就間接的注定了在使用上的嚴謹，更不能隨意，這是對社會復雜，對人們生活負責的一種現象。所以在使用Q390B鋼板之前，器械的檢查尤為重要。同樣的一些管道的內部和表面也是需要注意，看看內部和外表是否出現了生銹的跡象。如果出現了這樣情況，就需要及時的想辦法將眼前的銹跡都清理掉。
The use of Q390B steel plate area is relatively large, it is indirect is doomed to be in the use of rigorous, more can not be arbitrary, this is a phenomenon of social complexity, to people's life is responsible for. Therefore, the use of Q390B steel plate, the equipment is particularly important to check. The same number of internal and external surface of the pipeline is also need to pay attention to see if the internal and external appearance of signs of rust. If such a situation, we need to promptly clean out in front of the rust.
390B鋼板的性能再好，并不代表就是全能的。性能好不代表不管是在什么環境上，對產品的使用不聞不問都可以。但其實不是的，Q390B鋼板的盡管性能好，但是也是不能長時間在高溫下、潮濕的環境下運作，特別是在天氣不好的時候，只會大大降低Q390B鋼板的使用壽命，效益也會受到影響。所以在使用Q390B鋼板的時候，這些前提要格外注意。
The performance of 390B steel plate is again good, does not represent is all powerful. Good performance no matter what the environment, can use the product to go. But in fact not, despite the good performance of Q390B steel plate, but it is not a long time under high temperature and humid environment, especially when the weather is not good, will reduce the service life of Q390B steel plate will be affected greatly, benefit. So in the use of Q390B steel, these conditions should pay special attention to.
