304 stainless steel pipe advantages

The production standard of 304 stainless steel pipe is the ASTM standard of the United States, which belongs to a universal stainless steel pipe and is also the most widely used stainless steel type in China. 304 stainless steel pipe has many advantages, extremely long life, can be used for at least 70 years, or even hundreds of years. Corrosion resistance is one of the most prominent properties of 304 stainless steel pipe, in addition to heat resistance, insulation, high strength characteristics make it widely used in various fields. In addition, 304 stainless steel pipe is an environmentally friendly material, can meet people's requirements for health, but also can be 100% recycled.

304 stainless steel pipe rust causes

Although it is stainless steel, sometimes people will still encounter 304 stainless steel pipe rust, the main reasons can be divided into the following:

1, chloride ions cause stainless steel pipe rust. Chloride ions can accelerate the corrosion of stainless steel. From this point of view, the use of stainless steel environment is required, and pay attention to frequent wiping, pay attention to keep the surface dry.

2. There is no solid solution treatment in the production process. In simple terms, that is, the alloying element does not melt into the matrix, which will lead to the alloy content in the matrix is too low, so that the overall corrosion resistance of 304 stainless steel pipe is poor.

3, materials that do not contain titanium and niobium are very easy to occur intergranular corrosion, so it is best to add the above elements in the processing process, and the corrosion resistance is naturally improved after stable treatment.
