Do steel structural bolts have magnetism

People should not be very unfamiliar with steel structural bolts, as they are often seen in daily life and their usefulness is quite great. So some people have the question, is steel structural bolts magnetic? Many people say it is, but some also say it is made of stainless steel, how could it be magnetic? In fact, I agree with the previous statement that steel structural bolts are magnetic.

Because the raw material for making steel structural bolts is 304 stainless steel, which belongs to austenitic stainless steel. During production and processing, a small amount of austenite will be converted into Martensite. Martensite is magnetic, and everyone should know this knowledge. Therefore, 304 stainless steel is a little magnetic, but at most a little, steel structural bolts will also have a little magnetic.
