20g seamless steel pipe and alloy steel pipe distinguishing method I plant 20g seamless steel pipe and alloy steel pipe stacked together, because of a long time is not used, rusty, surface identification has been unclear, in addition to the use of spectrometry, what method Can be distinguished?
The method of differentiation is as follows:
The length of the model may not be the same. If you use the angle grinder to observe the sparks, if you know the respective carbon content, you can distinguish between: when the amount of charcoal is high, the fire bouquet is short and there are more tillers; the spherical sparks are less; the carbon content is less When it is low, the fire bouquet is long and there are fewer births, and there are more spherical sparks.
With a spectrometer you can take a high-strength axe and gently lick the end of the tube to see if the hardness should be able to distinguish between the open, and then use the hammer to beat the steel sound can also distinguish the contact: Bu Lingwei Zhang Bing Tel:
