201 stainless steel and 304 stainless steel difference?


1, from the hard work strength, Although the hardness of 201 stainless steel larger, but its toughness is far less than 304 stainless steel, so 304 will be better fortitude.

2, from the price point of view. Due to the quality of 304 stainless steel plate better than 201 stainless steel quality, so the price should be higher than 201 stainless steel. Past manufacturers claim that 304 stainless steel for the import of stainless steel, 201 stainless steel plate for domestic, so the 304 stainless steel is also very expensive to sell, but in fact now made in the domestic 304 stai201 stainless steel and 304 stainless steel difference?nless steel has also reached the same level of foreign technology.

3, from the appearance of view. 201 stainless steel with high manganese content, so the surface is bright but also with a dark black, we all know that high manganese stainless steel easy to rust. And 304 stainless steel more chromium, the surface showing matte, the two together is very obvious.

4, from the corrosion resistance. In fact, said the difference, the most important thing is that these two different materials, corrosion resistance, and 201 stainless steel containing high manganese, low nickel, although the price is cheaper than the 304 stainless steel products, but very easy to corrosion in the wet environment, and not Suitable for contact with strong acid and alkali items.

5, from the content. Stainless steel is not easy to rust because the formation of chromium oxide on the surface of steel can protect steel, 201 stainless steel is high manganese stainless steel, compared with 304 stainless steel hardness is greater, because of its high carbon and low nickel. 304 price is now more expensive because of its high nickel, this feature can ensure that it is better than the use of 201 stainless steel, will not rust.


6, from the chemical formula. 201 composition of 17Cr-4.5Ni-6Mn-N, is 301 stainless steel alternative steel. 201 stainless steel after cold processing with magnetic, for railway vehicles. And 304 stainless steel composition of 18Cr-9Ni, is the most widely used stainless steel, heat-resistant steel. For food production equipment, chemical equipment, home decoration and so have a decent performance.

Said so much 201 stainless steel and 304 stainless steel difference, which is better believe that we have a heart of the bar it In fact, when the choice of stainless steel products, but still suggest that you choose 304 stainless steel, because although the price looks more expensive than 201 stainless steel, but 304 has a higher long-term value of stainless steel is more expensive, durable durability is better, more cost Benefit.
