Shenzhen stainless steel screw manufacturer tells you how to distinguish 304 stainless steel screws

As we all know, there are many types of stainless steel. The two types of stainless steel 304 and 316 are widely used in daily life. In many models, how can we distinguish stainless steel 304? Let Shenzhen stainless steel screw manufacturer Shi Shi Tong tell you how to distinguish it!

First, distinguish from color. The color of stainless steel before pickling is different. The color of stainless steel 304 is brownish white, while that of general steel is a little brownish black. After pickling, the surface color of stainless steel is silver white and bright, and 304 will be jade, while that of general stainless steel is white and gray, with weak luster. This is the difference in color of stainless steel.

Secondly, it can be distinguished by magnetite. General steel has strong magnetism, stainless steel 304 is weak magnetism or even non magnetism. If the customer requires to do non-magnetic, Shenzhen stainless steel screw manufacturer Shi Shi Tong will do heat treatment to eliminate magnetism. Therefore, it can be found that the adsorption force of the two is obviously different. The third is to use steel to test the liquid medicine to distinguish, evenly apply the liquid medicine on the surface of 304 stainless steel, the liquid medicine will not change color; if used on other steel, the liquid medicine will turn brown red instantly.
