Product Introduction

Seamless 304 stainless steel tubing is a common stainless steel pipe, which has the advantages of corrosion resistance, high strength, high temperature and high pressure, etc. It is widely used in petroleum, chemical industry, medicine and other industries. Common models are listed below:

 

1. 304/304L: 304 and 304L are the same material, the difference is that 304L also adds some low-carbon elements, so that it has better welding performance and corrosion resistance.

 

2. 316/316L: 316 and 316L are the same material, compared with 304, the addition of molybdenum element, so that it has better corrosion resistance, especially in acidic environments.

 

3.321:321 is a titanium stabilized stainless steel, with good high temperature resistance and corrosion resistance, outstanding performance in high temperature environments.

 

4. 347:347 is a niobium stabilized stainless steel, with similar properties to 321, but more stable at high temperatures, suitable for high temperature and high pressure environments.

 

5. 309/309S: 309 and 309S have excellent performance in high temperature resistance, especially suitable for heaters, heat exchangers and other equipment at high temperatures.

 

6. 904L: 904L is a kind of high alloy stainless steel, with strong corrosion resistance, suitable for severe corrosion environment, such as Marine engineering, chemical equipment, etc.
