1, mechanical properties: in terms of fatigue strength, 201 hardness is larger, toughness is not as good as 304, or 304 fatigue resistance is better;
2. Price: take square tube 50*50*1.4*6000mm as an example, the price of 304 is 248 yuan/strip, while the price of 201 is 124 yuan/strip;
304 stainless steel plate quality is better, but the price is expensive, 201 is poor.
304 stainless steel is + imported stainless steel plate,201 is domestic stainless steel plate.
3, color: 201 is higher in manganese, the surface is very bright with dark light, high in manganese rust.
304 contains more chromium and the surface is matte without rust. The two kinds are compared when put together.
4, rust prevention: stainless steel is not easy to rust because the formation of chrome-rich oxide on the surface of the steel body can protect the steel body
201 stainless steel material belongs to high manganese stainless steel than 304 stainless steel hardness high carbon low nickel.
Similarly, in the outdoor environment, 304 stainless steel will not rust for 3-4 years, 201 stainless steel will rust after 6 months;
5. Ingredients: the difference between 201 stainless steel plate and 304 stainless steel plate is the problem of nickel:
201 is composed of 17cr-4.5 ni-6mn-n, which is an alternative to 301 stainless steel.
Magnetic after cold processing, used in railway vehicles.
Composed of 18Cr-9Ni, 304 is the most widely used stainless steel and heat resistant steel.
Used for food production equipment, common chemical equipment, nuclear energy and so on.
