Precision 304 316 316l stainless steel metal sheet is a kind of metal product that is relatively common in our lives. In fact, it has a very comprehensive application not only in life, but also in all walks of life. Then when we buy it, we need to pay attention to some of its purchase points, these points mainly focus on its anti-pollution and its density.
1. Anti-pollution of stainless steel plate
When selecting precision 304 316 316l stainless steel metal sheet, pour a small amount of ink or water on the surface of the board and let it stand for about two minutes, then rinse with water or wipe with a cloth to see if the remaining traces are obvious. If there are only a few traces, the tube body absorbs water Low rate, good pollution resistance, good physical and chemical properties; if there are obvious or serious traces, the degree of vitrification of the tube body is poor and the quality is poor.
2. Density of stainless steel plate
Another way to select precision 304 316 316l stainless steel metal sheet is to tap the plate body with your hand, and carefully distinguish whether the sound is crisp and pleasant. If there is a metal sound quality, the plate body has high density and good sintering; if the sound is rough and dull, the tube body The sintering degree is low, and the density is not high.
If the percussion sound is hoarse, then the precision 304 316 316l stainless steel metal sheet is of inferior quality, and there may even be cracks in the tube body. If you weigh the board by hand, under normal circumstances, if the hand feels heavy, the density will be high, the hardness will be high, and the strength will be good; otherwise, the texture will be poor.
