06CR19Ni10 stainless steel.

Executive standard: GB T20878-2007

jis g4303:2005

06CR19Ni10 is a kind of high-alloy steel that can resist corrosion in air or chemical corrosive media. It is a type of steel that has good surface and corrosion resistance, does not need to undergo surface treatment such as color plating, and gives full play to the inherent surface properties of stainless steel, and is commonly called stainless steel. Typical properties include 13 chromium steel, 18-8 chromium-nickel steel and other high-alloy steels.

The mechanism of stainless steel rust prevention is that the alloying elements form a dense oxide film, which isolates oxygen contact and prevents further oxidation. So stainless steel is not "stainless steel".

The rust of 06Cr19Ni10 material may be due to the following reasons:1Chloride ions are present in the environment of use.

Chloride ions are widely present, such as table salt, sweat stains, sea water, sea breeze, soil, etc. In the presence of chloride ions, stainless steel corrodes very quickly, even more than ordinary mild steel. Therefore, there are requirements for the use environment of stainless steel, and it needs to be wiped frequently, dust removed, and kept clean and dry.

In this way, he can be assigned a "misuse". There is an example in the United States: a company uses an oak container to contain a solution containing chloride ions, the container has been used for nearly 100 years, and it was planned to be replaced in the nineties of the last century, because the oak material is not modern enough, and the container leaks due to corrosion 16 days after replacing it with stainless steel.

2.It is not solution-treated. The alloying elements are not dissolved into the matrix, resulting in low alloy content and poor corrosion resistance in the matrix structure.

3.This titanium- and niobium-free material has a natural propensity for intergranular corrosion. The addition of titanium and niobium, combined with a stabilization treatment, can reduce intergranular corrosion.

It is a kind of high-alloy steel that can resist corrosion in the air or chemical corrosive medium, stainless steel is a kind of steel that has a beautiful surface and good corrosion resistance, does not have to go through surface treatment such as color plating, and gives full play to the inherent surface properties of stainless steel, and is used in many aspects, commonly known as stainless steel. Typical properties include 13 chromium steel, 18-8 chromium-nickel steel and other high-alloy steels. From a metallographic point of view, because stainless steel contains chromium, a thin chromium film is formed on the surface, and this film isolates the oxygen intrusive from the steel to resist corrosion.

To maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 12% chromium.

Answer: Austenitic stainless steel 06cr19ni10 is food grade, products such as: corrosion-resistant containers, tableware, furniture, railings, medical equipment. The standard composition is 18% chromium and 8% nickel, and it is a stainless steel that is non-magnetic and cannot be changed by heat treatment.

The question is whether it is food grade 304

If it's convenient, please evaluate my service after you are finished, if you are satisfied, please light up and praise for me, thank you, I wish you a happy and convenient life, please evaluate my service after you are finished, please light up and praise for me if you are satisfied, thank you, I wish you a happy life.

The fraction of the carbon content is between the carbon content. The code of the national standard stainless steel is by composition (see GB T20878-2007 or GB T3280-2007), and the following number represents the middle value of the previous element. That's right.

06Cr19Ni10 is the new standard grade, and the old standard grade is 0Cr18Ni9. The difference between the old and new grades is that the chromium content is different, the old one is generally more than 17% and the new one is more than 18%, the new national standard is equivalent to the Japanese standard SUS304 or TP304, the second floor is the wrong person 06cr 06 is not on behalf of chromium is carbon content, and the back 19 represents chromium is chromium (ge) not network (luo).Due to the CR content of 1% more, the new grade is generally 200 yuan-300 yuan and tons higher than the old grade.

Your 1cr18ni9 is a 302 material. 1 represents the carbon content, where the content is greater than chromium, and 18 represents 18% chromium content, but now the general content of more than 17% is up to standard. Ni is nickel, and 9 is 9% nickel content.

Now it's 8% to reach the target. This material is rare on the market. The market is 1cr18ni9ti (321), 0cr18ni9 (304, here 0 is not no carbon, but less than low-carbon).

Hope you figured it out.

According to the analysis of foreign samples, the pin key material corresponds to the domestic 1Cr18Ni9 stainless steel wire, and its tensile strength is as high as 1 400MPa, and the surface quality requirements are also very high. At present, domestic 1Cr18Ni9 austenitic stainless steel wire cannot be strengthened by heat treatment, and the tensile strength of raw materials is generally less than 900MPa. However, the high-strength 1Cr18Ni9 spring steel wire cannot effectively meet the special profile and specification requirements of the pin key.

Summary. 06Cr18Ni9Cu3 stainless steel This stainless steel is a steel grade with Cu added to grade 304 to improve cold workability. The corrosion resistance of steel is similar to that of 0Cr18Ni9.

It has good rust resistance in moisture, salt spray and ocean atmosphere; In acidic media, it is resistant to the corrosion of oxidizing nitric acid, and in reducing acid, it has poor corrosion resistance, but it is better than 0Cr18Ni9. For cold heading, the addition of copper, so that the cold work hardening tendency of the steel is small, the cold work hardening speed is reduced, so the maximum cold deformation can be obtained under a small forming force, this steel is mainly used in the production of cold heading fasteners and the manufacture and production of deep drawing and expanded cold forming components.

06CR18Ni9Cu3 is a grade of stainless steel. If it's not a good hail roll writing error, it is"Mi Youyu"；If it's a typo, it's usually thickness. 06Cr18Ni9Cu3 is likely to refer to "thick grade 06Cr18Ni9Cu3 stainless steel".

What does the previous mean?

06Cr18Ni9Cu3 stainless steel This stainless steel is a steel grade that adds Cu to grade 304 to improve the processability of Leng Zai Bishi. The corrosion resistance of steel is similar to that of 0Cr18Ni9. It has good rust resistance in moisture, salt spray and ocean atmosphere; In acidic media, it is resistant to the corrosion of oxidizing nitric acid, and has poor corrosion resistance in reducing acid, but it is better than 0cr18ni9.

For cold heading, the addition of copper, so that the cold work hardening tendency of the steel is small, the cold work hardening speed is reduced, so the maximum cold deformation can be obtained under a small forming force, this steel is mainly used in the production of cold heading fasteners and the manufacture and production of deep drawing and expanded cold forming components.

06CR18Ni9CU is the model stainless steel.

The biggest difference between the two stainless steels is that the carbon content in the chemical composition is quite different: the carbon content of 2Cr13 stainless steel, the carbon content of 0Cr18Ni9 stainless steel, and the difference in carbon content causes their different characteristics:

2Cr13 stainless steel has high hardness, wear resistance and toughness after heat treatment, and its mechanical properties are among the best in stainless steel, but the disadvantage is that the corrosion resistance and weldability are poor. It is mostly used to make parts in complex situations, such as stamping dies.

0Cr18Ni9 is our most commonly used 304 stainless steel, which has good corrosion resistance, machinability and high temperature resistance, but the heat treatment effect is not large, and it is mostly used for the welding of corrosion-resistant equipment.

The characteristics of the above two stainless steels are quite different, and it is not recommended to replace each other.
