Is 20 1 stainless steel tableware safe? Will 20 1 stainless steel rust? Advantages and disadvantages of 20 1 stainless steel

Stainless steel is a common material in life, which can be used on stairs and tableware. There are many kinds of stainless steel, among which 20 1 stainless steel is unknown to many people, and they don't know whether it can be used as tableware. Let's take a look at the safety of 20 1 stainless steel tableware with Bian Xiao. By the way, will 20 1 stainless steel rust? Are there any advantages and disadvantages?

1.20 1 Is stainless steel tableware safe?

1 and 20 1 Are stainless steel tableware safe? 20 1 stainless steel tableware is unsafe. 200 series stainless steel is not food grade stainless steel, which has poor corrosion resistance and is easy to precipitate heavy metals such as nickel and chromium. It is not suitable for pots, bowls, cups and other containers that come into contact with food, especially oil, salt, sauce and vinegar.

2, 20 1 stainless steel, acid and alkali resistance, high density, polishing without bubbles and pinholes. , is a high-quality material for making all kinds of watchcases and watchbands. Mainly used for decorative tubes, industrial tubes and some lightly stretched products.

3. Tableware is generally made of 304 stainless steel, which belongs to high nickel stainless steel and has strong rust resistance. The composition of 304 stainless steel is iron+18% chromium +8% nickel, which can resist chemical oxidation. This kind of stainless steel is No.304 in Japanese industrial standard.

Second, will 20 1 stainless steel rust?

1 and 20 1 Will stainless steel rust? 20 1 stainless steel will rust under certain conditions, such as soaking in salt water, but it is extremely difficult to rust in daily environment. Stainless steel is not easy to rust because it contains nickel, while 20 1 stainless steel has less nickel than 304 stainless steel, so it is easier to rust than 304 stainless steel.

2, 20 1 is a high manganese content, the surface is very bright and dark, and high manganese content is easy to rust. 20 1 stainless steel, with certain acid and alkali resistance, high density and polishing without bubbles and pinholes, is a high-quality material for making various watchcases and watchbands. Mainly used for decorative tubes, industrial tubes and some lightly stretched products.

Advantages and disadvantages of 20 1 stainless steel

Advantages of (1)20 1 stainless steel

20 1 is a kind of stainless steel. Chromium content is 16- 18, nickel content is only 0.3- 1.2, Lianzhong LH nickel content is about 0.3, L 1 nickel content is about 1, and La nickel content is earlier than 0.6.

The nickel content of 20 1 is low, only 0.08-0.3. There are many 20 1 calendered plates on the market, which are much cheaper. 20 1 There are many kitchen equipments, but not many tableware. The surface of 20 1 is slightly worse than that of 304, and the stamping performance is also poor.

(2) Defects of 201stainless steel

The chromium content is lower than 18% and the low nickel content is unbalanced, forming ferrite. Therefore, the chromium content in 200 series stainless steel is reduced to 13.5%- 15%, and in some cases to 13%- 14%. Its corrosion resistance cannot be compared with that of 304 and other similar steels.

In addition, manganese and copper in some cases will reduce the re-passivation effect under the common acidic conditions in sedimentary areas and fracture corrosion sites. Under these conditions, the failure rate of 200 series steel is 10- 100 times that of 304 stainless steel.

The above is about whether 20 1 stainless steel tableware is safe, whether 20 1 stainless steel will rust, and the advantages and disadvantages of 20 1 stainless steel. I hope I can help you!
