Stainless Steel 201 vs Stainless Steel 403

Stainless Steel 201 vs Stainless Steel 403

201 is 200 series-chromium-nickel-manganese austenitic stainless steel, 304-that is, 18/8 stainless steel. The GB grade is 0Cr18Ni9. 430—ferritic stainless steel, for decorative purposes, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance. Stainless iron 430 does not contain nickel, is easy to rust, and is magnetic. The metallographic structure is austenite

Stainless steel 201 contains 3.5-5.5% nickel, but 201 produced by domestic manufacturers rarely adds nickel. I know that 201 material is more prone to rust than 430. There are many decorative tubes in 201, so it is recommended not to use this material for plates.

For this reason alone, I should choose 430

Mechanical strength: I personally feel that 201 is stronger than 430

The difficulty of stainless CNC machining depends on what object is being processed.

So I still choose 430

PS: Due to too many profiteers, it is difficult to buy 201 with a nickel content of 3.5-5.5%. If you can buy 201 with a nickel content of 3.5-5.5%, I recommend 201.

Which stainless steel 304, 403 or 201 is more expensive?

Stainless steel 304 is expensive. 304 stainless steel is more expensive because the nickel content in stainless steel is higher than that of 201 stainless steel, which is commonly known as the worst stainless steel on the market. 304 is also more expensive than 430. It can be distinguished by magnet or spectrum test. 304 contains chromium and nickel, especially because the price of nickel is too high, the cost of smelting 304 stainless steel is very high. The nickel content is 8 to 11%, which accounts for a high cost ratio. Nickel has a good anti-corrosion effect. 430 is a chromium-containing stainless steel that does not contain nickel. Its cost is much lower, its price is relatively low, and its anti-corrosion performance is low. Use a magnet to attract it, the one that doesn’t attract is 304, and the one that attracts is 430, or you can distinguish it by comparing the chemical composition with the standard using spectrum analysis.

Stainless steel kettles are available in 201 stainless steel and 304 stainless steel. Which steel is better? Also talking about 403, which type of steel is better?

Among these types of stainless steel, 304 is the best; 201 is the second best; and 403 is the worst. Among them, 304 and 201 are austenitic stainless steels with superior corrosion resistance, and 403 is martensitic stainless steel. Of course, 304 stainless steel is the first choice as a kettle material, because 304 has the best corrosion resistance among these three materials. Good corrosion resistance means less heavy metal precipitation, which is very important to human health.

Which is more expensive, stainless steel 403 or 201?
Hello, commonly used stainless steel plates are divided into two types: 201 and 304. The actual composition is different. 304 is of better quality but more expensive, and 201 is worse. 304 is imported stainless steel plate, and 201 is domestic stainless steel plate.

Stainless steel question: What are the differences between the four grades of stainless steel: 201, 304, 403 and 430? Which one has better quality?

430 is stainless steel, 201 and 430 are both more than ten yuan, 304 is more than twenty yuan, and 403 is the cheapest. .

Which is better, 201 stainless steel or 304 stainless steel?

Of course 304 is better. Compared with 304, 201 has high carbon content and low nickel content, so its hardness is greater, but its anti-corrosion ability is poor, so it is not suitable for places with high humidity. Moreover, 201 is mainly used for decoration and is not suitable for tableware.
