Popular Grades

•304 Series: It is the most widely used grade, with good comprehensive performance, excellent corrosion resistance and formability, and is widely used in food production equipment, ordinary chemical equipment, nuclear energy and other fields.

•316 Series: It has better corrosion resistance than 304 series, especially in chloride ion environment, and is often used in marine environment, chemical industry and other occasions with high corrosion requirements.

Popular Q&A

Q: What are the main factors affecting the corrosion resistance of stainless steel heavy wall tubes?

A: The main factors include the chemical composition of stainless steel, especially the content of chromium, nickel and other elements; the surface finish of the tube, a smooth surface is more corrosion-resistant; and the environment in which the tube is used, such as temperature, humidity, and the type and concentration of corrosive media.

Q: How to choose the appropriate grade of stainless steel heavy wall tubes?

A: It needs to be selected according to the specific use environment and requirements. If it is used in general corrosive environment, 304 series can be selected; if it is used in high chloride ion environment or high temperature environment, 316 series or 310S and other high alloy grades should be considered; if it is used in high pressure environment, the wall thickness and strength of the tube should also be considered.

Q: What are the common processing methods for stainless steel heavy wall tubes?

A: Common processing methods include cutting, welding, bending, and threading. When cutting, attention should be paid to using appropriate cutting tools and techniques to avoid affecting the performance of the tube; when welding, it is necessary to select the appropriate welding process and filler metal to ensure the quality of the weld; when bending and threading, it is necessary to consider the plasticity and hardness of the tube to avoid cracking and other problems.
