Stainless steel is a popular material used in various applications due to its strength, durability, and corrosion resistance. However, not all stainless steel is created equal. There are different grades of stainless steel, and it can be challenging to determine which one you have. Here are some ways to tell the difference between stainless steel 304 and 201:
Magnetic Properties
Stainless steel 304 is non-magnetic, while stainless steel 201 is magnetic. You can use a magnet to check if the stainless steel is 304 or 201. If the magnet sticks to the metal, it is most likely 201 stainless steel.
Corrosion Resistance
Stainless steel 304 has better corrosion resistance than 201 stainless steel. If the stainless steel is exposed to high temperatures, saltwater, or acidic conditions, the 304 stainless steel will resist corrosion better than the 201 stainless steel.
Appearance
Stainless steel 304 has a higher nickel content than 201 stainless steel. As a result, stainless steel 304 has a brighter, more polished appearance than 201 stainless steel. If the stainless steel has a dull, matte finish, it is most likely 201 stainless steel.
These are just a few ways to tell the difference between stainless steel 304 and 201. If you are still unsure, you can consult with a professional or use specialized testing equipment to determine the grade of the stainless steel.
