Both stainless steel material and carbon steel belong to steel structure. Because the materials contained in the two manufacturing are different, there is still a difference in themselves. Carbon steel contains carbon elements, while stainless steel contains aluminum alloys and other materials.   2. The density is different. The density of carbon steel is higher than that of stainless steel material.   3. The composition is different. Stainless steel means stainless steel, acid and alkali resistance, and oxidation resistance, so it is called stainless steel. Carbonic acid is a carbon alloy with a carbon content of 0.0217% to 2.10%, also called carbon steel, which contains a small amount of silicon.   4. The resistance is different. Stainless steel material  has a higher resistivity, while carbon steel has a lower resistivity.   5. Magnetism is different. Stainless steel material has magnetic induction. When stainless steel is cold processed, it will produce magnetic induction. It can be demagnetized when it is scalded with hot water.   Stainless steel material is usually sold wholesale in the form of stainless steel coils, stainless steel plates, stainless steel strips, stainless steel profiles(angle steel, channel steel), and stainless steel bars (round steel, square steel, etc.).
