Q390B钢板的使用面积比较大，也就间接的注定了在使用上的严谨，更不能随意，这是对社会复杂，对人们生活负责的一种现象。所以在使用Q390B钢板之前，器械的检查尤为重要。同样的一些管道的内部和表面也是需要注意，看看内部和外表是否出现了生锈的迹象。如果出现了这样情况，就需要及时的想办法将眼前的锈迹都清理掉。

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钢板的性能再好，并不代表就是全能的。性能好不代表不管是在什么环境上，对产品的使用不闻不问都可以。但其实不是的，Q390B钢板的尽管性能好，但是也是不能长时间在高温下、潮湿的环境下运作，特别是在天气不好的时候，只会大大降低Q390B钢板的使用寿命，效益也会受到影响。所以在使用Q390B钢板的时候，这些前提要格外注意。

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.
