| 常见的三种方法 Three common methods 方法一：需求专业人士的帮忙，专业人士就能凭借钢材表面的颜色以及光滑程度分辨钢材的真假 Method 1: With the help of professionals, professionals can distinguish between true and false steel products by the color and smoothness of the steel surface. 方法二：专门304不锈钢检验药水，这种药水在一般的五金店都是可以购买的到，因此不用担心货源的问题。304不锈钢材，它经过药水的检验在3分钟内是无任何变化的，底部颜色略微变深。此外201不锈钢材，药水会在瞬间变成深棕红色，202不锈钢钢材，药水会在5秒内变成淡棕红色，301不锈钢材，药水会在1-2分钟变成淡砖红色 Method 2: Specialized 304 stainless steel inspection potion, this potion can be purchased in general hardware stores, so do not worry about the problem of supply. 304 stainless steel, it has no change in 3 minutes after the inspection of the potion, the bottom color is slightly darker. In addition, 201 stainless steel, the potion will instantly become dark brown red, 202 stainless steel, potion will become light brown red in 5 seconds, 301 stainless steel, potion will become light brick red in 1-2 minutes. 方法三：磁铁，304不锈钢材的磁性是比较偏小的，因此我们可以去购买专门的磁铁根据磁性的大小来分辨304不锈钢材的真假。磁性如果偏大的话，那么应该就是202不锈钢材 Method 3: Magnets, 304 stainless steel is relatively small magnetism, so we can buy special magnets to distinguish 304 stainless steel according to the size of magnetism. If the magnetism is too large, it should be 202 stainless steel. |
