Ways to identify 304 stainless steel
It is not easy to produce 304 stainless steel. To maintain the inherent corrosion resistance of stainless steel, the steel from stainless steel supplier in China must contain more than 18% of chromium, more than 8% of the nickel content. 304 stainless steel is a grade according to American ASTM standards stainless steel.
Here are some easy ways to identify 304 stainless steel. We can share with each other together if you have interest in it or you need to identify it before you buy it. First of all, We can see authenticity through stainless steel syrup discrimination nickel content. It is a very simple, time-saving and money-saving way to identify it. You can identify 316 from wholesale 316L stainless steel by this way too. In addition, with spark spectrometer identification, the accuracy is greater than the syrup, but experience requirements are relatively high. What’s more, radioactive direct reading, this high accuracy, but the equipment cost is too high, there is proposed long-term bulk cargo in and out of the equipment.
Finally, block sampling laboratory tests is the highest accuracy for high quality 304 stainless steel. It has high and low prices, but time consuming, also damage a little raw material.
