3 3/4 inch plate JIS SMA400AW atmospheric corrosion resisting steel stock

When cutting extra thick JIS SMA400AW atmospheric corrosion resisting steel steel plates, the cutting speed should not be too fast. Many processing and production industries will encounter such problems, that is, in order to speed up the cutting of extra thick steel plates, many details will be ignored in the process of these process operations, so it is easy to produce waste parts, and some plates JIS SMA400AW atmospheric corrosion resisting steel will crack. So when cutting extra thick steel plates, you must pay attention to the speed, which can not be too fast. Low-speed processing can effectively improve work efficiency.
