Are steel structure bolts magnetic

We should not be very strange to this kind of product of steel structure bolt, because we often see it in our daily life, and its use is quite big. So some people have such a question, say steel structure bolt is magnetic? Many people say yes, but some people say that it is made of stainless steel. How can it be magnetic? In fact, I agree with the former saying that steel structure bolt is magnetic.

Because, ah, the raw material of steel structure bolt is 304 stainless steel, which belongs to austenitic stainless steel class. In the process of production and processing, a small amount of austenite will be transformed into martensite, and martensite is magnetic. We should all know this knowledge. Therefore, 304 stainless steel is a little magnetic, but at most it is a small amount. Steel structure bolt also has one It's magnetic.
