First of all, the three most common stainless steel pipe materials are 201, 304, and 316 stainless steel pipes.
1. 201 stainless steel pipe
It has the characteristics of certain acid and alkali resistance, high density, no bubbles, no pinholes in polishing, etc. Mainly used for decorative pipes, industrial pipes, and some shallow-stretched products.
2. 304 stainless steel pipe
It is a universal stainless steel material, and its rust resistance is stronger than that of 200 series stainless steel materials. The high temperature resistance is also relatively good, and the general operating temperature limit is less than 650 °C. 304 stainless steel pipe has excellent stainless corrosion resistance and good resistance to intergranular corrosion. For oxidizing acids, it was found in the experiment that 304 stainless steel pipes have strong corrosion resistance in nitric acid with a concentration of ≤65% below the boiling temperature. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.
3. 316 stainless steel pipe
It is a kind of hollow long round steel, which is mainly used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and so on. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, etc.
From the perspective of composition, 201 stainless steel tube has less chromium and nickel content, and its corrosion resistance is not as good as 304 and 316 stainless steel tube. If stainless steel guardrail is used indoors or in relatively dry northern areas, it can be used, and the price is cheap and cost-effective. , The corrosion resistance of 304 stainless steel and 316 stainless steel is almost the same, but when the content of chloride ions in the medium is very high, 316 stainless steel is more suitable, and the specific situation is analyzed. For particularly humid coastal areas, 316 stainless steel pipe is recommended.
