304 Stainless Steel Problems 10, 304 Stainless Steel Problems

The easiest way to detect: buy a bottle of potion in the stainless steel market, point the potion to the stainless steel, and then put one pole of the battery on the stainless steel, one pole on the potion, to see if there is any discoloration, if the red does not fade, it is 304, if there is fading, it is not 304, now many bad manufacturers, with 201 or 301 these materials instead of 304, and then write 304 on the surface, so only we must know how to distinguish.

I don't know very well about the potion you said, it is generally a reliable point to detect the elements of steel, and you can see how many elements you can see at a glance, and you can't fake it.

0cr19ni9

0cr18ni9

The test came out and it was clear as soon as it was checked.

Alas. If you don't need to measure, you won't meet the standard.

The national standard is 0CR18NI9, but during production, the quality assurance income of major factories is greater than NI and CR is greater than . Baoban, TISCO, etc. are all. So if you test, up to 8 nickels is considered qualified.

In fact, the door panels, as well as the decoration pipes, these materials are fake. The factory that made this was only six nickels of 304 when it left the factory. Selling these is even more fake, often selling 201 as 304.

You can go to the stainless steel market to buy a stainless steel test solution, the main principle is: to determine the stainless steel material by detecting the content of nickel and molybdenum in stainless steel, and the chemicals in the potion react with the nickel and molybdenum in stainless steel to form a complex of specific colors, so as to know the approximate content of nickel and molybdenum in stainless steel.

For example, the potion of 304 (N8), when the nickel content of the stainless steel being measured is greater than 8%, it will show a specific color, and the nickel content is greater than 8%, which is the most important feature of 304 stainless steel, and it is also the main reason why it is different from other grades of stainless steel. The material of 301 can be measured with (n6).

I don't know the specific door now, I specialize in stainless steel, now 304 (the market base price is 18,000 per ton, and the cost per square meter is about 250, plus the cost of labor, processing, transportation, etc., it is about 400 yuan, and the specific ** depends on the market, I am calculated by the formula.

304 stainless steel: one of the most widely used chromium-nickel stainless steels.

304 stainless steel will rust.

1. However, it is not easy to rust, as long as 304 stainless steel is not placed in salt water for a long time, it will not rust.

2. Because 304 stainless steel rusts because it encounters chloride ions, the two will react after contact, and corrode and rust.

304 stainless steel to prevent rust.

1. The newly bought 304 stainless steel should be washed first. Prepare cooking oil, white or rice vinegar and a steel brush, pour a little rice vinegar into the pot and heat until the rice vinegar is boiling, turn off the heat. At the same time, use a steel brush dipped in rice vinegar to brush the inside of the pot carefully and vigorously several times to remove the impurities in the stainless steel pot.

2. After brushing clean, pour out the white vinegar or rice vinegar, rinse with water, and then heat the pot over high heat until all the water droplets have evaporated. At this time, turn to medium-low heat, pour in cooking oil, and then keep shaking the pot to make the cooking oil stick to the inside. Keep the heat low for about 3 minutes and pour out the oil.

3. Wash the pot with water and wipe it dry, then the pot will be very oily. When cooking things in the future, turn on low heat first, let the oil evenly adhere to the surface of the pan before stir-frying, it will not be easy to stick to the pan<>

In our daily life, there are products made of stainless steel everywhere, such as the thermos cup we drink, and you will see the logo of 304 stainless steel at the bottom, so what kind of material is 304 stainless steel? How to identify the authenticity of 304 stainless steel?

1. What is 304 stainless steel.

Stainless steel is a relatively wide range of materials, it has the characteristics of high temperature resistance, even if the temperature reaches 1200 degrees Celsius, there is no need to worry, at the same time, its corrosion resistance is also very good, can be widely processed, with weldability, so it is widely used in the food industry and chemical industry.

The name of stainless steel originated in the United States and Japan, and it is customary to distinguish the element content as a name in China, for example, the chromium element of this 304 stainless steel can reach 19% 20%, and the content of nickel element reaches about 10%.

2. How to identify 304 stainless steel.

1. If you have a magnet on hand, you can identify stainless steel through the magnet. Because its magnetic properties are relatively small, it cannot be adsorbed with magnets. If the magnetism is too large, it means that it does not belong to 304 stainless steel, but may be 202 material.

2. At the same time, we can also use special potions, because it is not easy to change color within a few minutes after dropping into the potion. But like 201 stainless steel, it will change color immediately after being dropped into the potion and will turn red. There is also 301 stainless steel that can turn brick red in about two minutes after being tested by dropping into the potion.

3. There is also a professional testing method to judge whether it is 304 steel by the surface and smoothness.

3. What products can 304 stainless steel be made of?

304 stainless steel has corrosion resistance and is widely used in life, such as our kitchen utensils, stainless steel woks, and tableware, etc., are made of 304 stainless steel.

And because it has reached the food level, the thermos cup used is also made of 304 material.

The above content is about what 304 stainless steel is, and what is the way to identify whether it is real 304 stainless steel, and what products are available in our daily life.

304 stainless steel is a common material in stainless steel, with a density of 18 8 stainless steel in the industry. High temperature resistance 800, with good processing performance, high toughness characteristics, widely used in industry, furniture decoration industry and food and medical industry.

The common labeling methods on the market include 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally represents the national standard production, 304 generally represents the ASTM standard production, and SUS304 represents the Japanese standard production.

Why don't you buy it quietly to count the real 304 stainless steel, ** on the watch parameters case is 304 steel, the actual aluminum alloy, easy to oxidize half a year to rot, so consumers on the domestic goods on ** most of the fakes? This is that domestic goods cannot be graded, and the impression in the hearts of the people has become a domestic goods. **How not to supervise the reference data, and the products that do not match the physical goods should be fined, and tens of thousands of fines should be imposed on it.

Rush it off the shelves and close the store. Hope it helps. If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress.

Finally, I wish you good health and a good mood!
