Simple method of distinguishing stainless steel 304 and 201
Thread Content
There are a bunch of 304 and 201 stainless steel connectors mixed together. How can I distinguish the two?
There are many stainless steel inspection potions in the stainless steel market. Different steel materials have different colors. You can try them.
I have a colleague who is a stainless steel expert from TISCO. He should be able to answer your questions. If you want to know more, please contact 13934219977
If you just want to simply distinguish between 304 and 201, you can use the potions mentioned above and mainly detect the Mn content. This potion is very cheap and is used by many traders in the Wuxi stainless steel market.
Buy a gun that can identify materials, and you will know what materials they are after a dozen shots.
5# zjp This advertisement is too good. . . . . . To put it bluntly, isn't it just using different metals in the steel to distinguish them by the difference in color after reacting with different reagents? Electricity is just to speed up the reaction. What kind of technology is the world's leading? Don't brag too much about the cowhide.
The key is that there are a lot of connectors that need to be distinguished, and it would be too troublesome and wasteful to use potions.
