Why does stainless steel rust?

The size of the corrosion resistance of stainless steel is changed with the chemical composition of its steel itself, intergranular structure, use conditions and type of environmental media. Not any kind of stainless steel can resist corrosion in any environment without rusting.

Stainless steel surface has a layer of chromium-rich oxide film (protective film) to prevent the infiltration of oxygen atoms and oxidation, so as to obtain the ability to engage in rusting. Once there is some reason, this film is constantly destroyed, the oxygen atoms in the air or liquid will constantly infiltrate or the iron atoms in the metal will constantly precipitate out, forming loose iron oxide, and the metal surface will be subject to constant rusting.

What is the meaning of L in 304,301,316 material?

L stands for low carbon, e.g. 304L contains less carbon than 304.

What is the meaning of 1/2H,3/4H in 304 etched stainless steel strip?

304 stainless steel material in the 1/2H,3/4H refers to the hardness of the material, generally 304 stainless steel material if marked as 1/2H, then its hardness is generally in 250-310 degrees, 3/4H is generally in about 350 degrees.

Shenzhen do high-end stainless steel etching processing factory

Zhuo Li Da is a high-end stainless steel etching processing plant in Shenzhen, the current situation of the etching plant in Shenzhen is: many small factories in Shenzhen do etching, but the precision capabilities and environmental requirements of many are not up to.

Zhuo Li Da has completely solved these problems at present. Copper and stainless steel and other materials, metal etching process in China has about 10-20 years of development, while in foreign countries at least 30-50 years of development, copper etching this process for the development of electronics, communications and other fields, playing an important role in replacing hardware stamping. Europe, the United States, Japan and other regions is already fully automated production, in China can only say that it is still just starting, but the speed is fast, the best etching processing in the Shenzhen area should be some Japanese, Hong Kong-owned factories, but they are producing large quantities of stable orders, small orders are often not accepted.

In addition to foreign-funded factories, domestic factories in the Shenzhen area to do copper etching processing on a large scale, such as Zhuo Li Da. Zhuo Li Da is specializing in flat copper precision etching, Baidu, they joined the world etching industry association, the introduction of a large number of imported equipment, specializing in high-end precision etching corresponding stainless steel and copper become the leading etching process.

Where to do high precision etching factory in Shenzhen

Jolida is an ISO certified factory focusing on high-end precision etching, depending on what kind of products you are making.

Really high precision etching requires a lot of related supporting equipment, personnel, and technology.

Do high precision etching factory you must understand there is no purification workshop, which is convenient and important, otherwise the products made will have broken lines, broken points, etc..

It also depends on whether the etching equipment of this company is advanced and whether the relevant technical standards are complete.

There is another important point, whether to meet the environmental requirements, such as: is not the government permit discharge, there is no sewage recycling, treatment? Because the etching process is a more polluting industry. High precision etching is still mainly concentrated in South China, East China. There are mainly some Japanese and American enterprises.

After all, foreign countries are ahead of China in this area. Shenzhen I learned is Zhuolida do etching, there are more than ten years, service some high-end etching products project.

What is the meaning of H,S in the material marking of etched stainless steel?

H and S stand for high temperature resistance, such as 310S than 310 high temperature resistance, 304H than 304 heat resistance.

Where is the etching factory in Shenzhen

There are few etching factories in Shenzhen left due to environmental problems, Zhuolida etching in Shenzhen Fuyong, since its establishment in 1999, has its own environmental protection approval, self-built sewage treatment system, the company's core values: people-oriented, customer first, low-carbon environmental protection, technological innovation.

What materials can be done with metal etching?

Generally speaking, there are stainless steel, copper alloy, titanium alloy, etc. Stainless steel commonly used 304 301 316, etc., copper alloy C5191, C5210, C7701 H65, H63, etc., special metals have aluminum alloy. Titanium alloy, etc., special metals need to be formulated with different potions can be etched.

What is the maximum size of etching that can be done?

Our maximum etching area is 600*700mm, which is related to the size of the exposure machine and etching machine in the production process.。

When to choose etching process to save cost?

Hardware parts can choose stamping can also be etched processing, such as new product sampling, open the mold high cost, long time, it is best to choose etching processing, low cost delivery time, the fastest 8 hours delivery!
