What does 18 0 and 18 8 mean in stainless steel?

These two sets of numbers are about chromium-nickel inside stainless steel.

The value of the content, 18 0 represents the chromium content of 18%, which basically does not contain nickel; 18 8 refers to 304 stainless steel, chromium content 18%, nickel content 8%.

The industry often puts 304 stainless steel pipes.

It is called 18 8 stainless steel pipe, but it also has 06CR19NI10,304, SUS304 These three logos and names, 06CR19NI10 generally means the national standard production, 304 generally represents the American ASTM standard.

Production, SUS304 marked as the standard production of the Japanese standard.

These two sets of numbers are a value about the chromium and nickel content in stainless steel, the former represents a chromium content of 18%, which basically does not contain nickel, and the latter mainly refers to 304 stainless steel, with a chromium content of 18% and a nickel content of 8%.

18 8 refers to the 304 stainless steel pipe, the industry often calls the 304 stainless steel pipe 18 8 stainless steel pipe, but it also has 06cr19ni10, 304, sus304 these three identities and names, 06cr19ni10 generally means the national standard production, 304 generally means the United States ASTM standard production, SUS304 marks the Japanese standard production.

Stainless steel 18 10 is stainless steel containing 18% chromium (Cr) and 10% nickel (Ni).

The representative of 18 10 stainless steel is 316 stainless steel, and the others have 316L stainless steel.

316H stainless steel, 316Ti stainless steel, 316NB stainless steel, 316N stainless steel, 316LN stainless steel, etc.

With 18 8 stainless steel Hongmin jujube (such as 304 stainless steel.

Compared to 18 10 stainless steel, it has stronger corrosion resistance.

18 10 is a high-purity non-abrasive steel, which is used to make medical equipment and high-end tableware.

The main components of stainless steel are nickel and chromium, and the hand 18 10 is 18% chromium and 10% nickel.

<>18-8 stainless steel is a ferroalloy containing 18% chromium and 8% nickel, which is a very common stainless steel that can resist chemical oxidation, and this stainless steel is No. 304 in the JIS code, so it is also called 304 stainless steel.

Stainless steel is an alloy composed of iron, chromium, carbon and many different elements, with iron being the main component element and chromium being the main alloying element. Generally speaking, the chromium content must be at least accounted for to be called stainless steel, because if the chromium content is insufficient, the stainless steel surface will not be able to form dense chromium oxide.

protective film, which loses its anti-corrosion function. If the chromium content is sufficient, it is not easy to rust in the atmosphere at room temperature. There are more than 180 kinds of standard stainless steel available on the market, but the so-called stainless steel usually refers to 300 series stainless steel (especially 304 series stainless steel).

Stainless steel is stainless acid resistant steel.

The abbreviation of the steel resistant to weak corrosive media such as air, steam, water or stainless steel is called stainless steel; The steel that is resistant to corrosion by chemically corrosive media (acid, alkali, salt and other chemical corrosion) is called acid-resistant steel. Due to the difference in chemical composition between the two, their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical media corrosion, while high tarding resistance and acid steel are generally stainless steel. The term "stainless steel" does not simply refer to one type of stainless steel, but to more than a hundred industrial stainless steels, each developed with good performance in its specific application area.

The key to success is to first understand the use and then determine the right steel grade. There are usually only six types of steel that are relevant to the construction of buildings. They all contain 17-22% chromium, and the better steel grades also contain nickel.

The addition of molybdenum can further improve atmospheric corrosivity, especially for chlorides.

Atmospheric corrosion. Generally speaking, the hardness of stainless steel is higher than that of aluminum alloy, and the cost of stainless steel is higher than that of aluminum alloy.

18 8 refers to 304 stainless steel, chromium content 18%, nickel content 8%.

The industry often calls 304 stainless steel pipes 18 8 stainless steel pipes, but it also has 06cr19ni10, 304, sus304 these three logos and names, 06cr19ni10 generally means the national standard production, 304 generally means the american astm standard production, and the sus304 marks the Japanese standard production.

Difference Between Stainless Steel 18 10 and 18 8.

1. The content of nickel is different.

18-8 stainless steel: iron + 18 chromium + 8 nickel; 18-10 stainless steel: iron + 18 chromium + 10 nickel. 18-8 stainless steel is No. 304 in the JIS code, so it is also called 304 stainless steel;

2. The oxidation resistance is different.

18-10 stainless steel has 10 nickel to make it more durable and corrosion-resistant. This stainless steel is called 18-10 stainless steel. In some tableware descriptions, there is a statement similar to "using 18-10 the most advanced medical stainless steel".

What does stainless steel 18-0 mean?

What does stainless steel 18-0 mean? Hello dear, 18-0 should contain 18 chromium, nickel-free material. Stainless steel:

The corrosion resistance of rusted steel decreases with the increase of carbon content, therefore, the carbon content of most stainless steels is low, and the maximum is not exceeded, and the WC (carbon content) of some steels is even lower than that of 00Cr12). The main alloying element in stainless steel is CR (chromium), and it is only when the CR content reaches a certain value that the steel is corrosion-resistant. Therefore, stainless steel generally has a cr (chromium) content of at least.

Stainless steel also contains elements such as Ni, Ti, Mn, N, Nb, Mo, Si, and Cu. The corrosion resistance of stainless steel decreases with the increase of the carbon content of the code macro, therefore, the carbon content of most stainless steels is low, and the maximum is not exceeded, and the WC (carbon content) of some steels is even lower than that of 00Cr12). The main alloying element in stainless steel is CR (chromium), and it is only when the CR content reaches a certain value that the steel is corrosion-resistant.

Therefore, stainless steel generally has a cr (chromium) content of at least. Stainless steel also contains elements such as Ni, Ti, Mn, N, Nb, Mo, Si, and Cu. I hope I can help you.
