What is the difference between 201 and 304 stainless steel？

Which stainless steel is better, 304 or 201?

304 stainless steel has good toughness: 201 stainless steel material is relatively hard, and with a little steel, it is more prone to cracking. 304 stainless steel vacuum bottles do not rust because they contain nickel. 304 stainless steel is stronger and has much better fatigue resistance than 201

Is 304 stainless steel good quality?

Durability: The structural composition of SS 304 stainless steel gives it high load-bearing capacity, making it strong under various physical conditions, ensuring durability and reliability. These characteristics make SS 304 the preferred material for heavy-duty applications that require long-term strength and durability

 

Does 304 stainless steel rust?

304 stainless steel will rust, but it is extremely difficult to rust. As long as it is not placed in salt water for a long time, it will not rust

 

Can 201 stainless steel rust?

Ingredients: 201 sheet metal with high metal content, bright appearance, dark brightness, and easy rusting. 304 contains more chromium, has a matte surface, and will not rust. The content is another important difference between 201 and 304.

 

What is equivalent to 304 stainless steel?

For more severe corrosion conditions, when 304 stainless steel is too sensitive to pitting or crevice corrosion caused by chloride or general corrosion in acidic applications, 316 stainless steel is usually used instead.
