304 stainless steel plates are popular because of their good processing properties and high toughness. However, in recent years, due to the proliferation of low-nickel and high-manganese steels, the stainless steel market is confusing, and consumers cannot distinguish stainless steel material grades with the naked eye.
It is easy to be misled by the propaganda of the merchants. Some merchants only promise that the oral propaganda is 304 stainless steel plate, but not marked on the product logo, although some are marked as 304 stainless steel plate, the actual price is relatively low 201, 202 or low nickel. High manganese steel, etc.
What is the difference between 201 and 304 stainless steel? how to choose?
1, commonly used stainless steel plate is divided into 201# and 304# two models, the actual is the composition is different, 304# quality is better, but the price is expensive, 201# is worse. 304# is imported stainless steel plate, 201# is domestic stainless steel plate.
2. The composition of 201# is 17Cr-4.5Ni-6Mn-N, which is a Ni steel type, which is magnetic after cold working and is used for railways and vehicles.
3, 304 # composition is 18Cr-9Ni, is the most widely used stainless steel, heat-resistant steel, used in food production equipment, Xitong chemical equipment, nuclear energy.
