The stainless steel heat exchange tube is one of the elements used in the heat exchanger for the heat exchange between the two media, and is placed in the cylinder.
There are two commonly used materials for stainless steel heat exchange tubes, do you know them? These two stainless steel materials are 304 and 304L stainless steel respectively, so let’s talk about the functions of these two materials in detail.
304 stainless steel has excellent thermal conductivity, and is often used in stainless steel heat exchange tubes, because the core function of the heat exchange tube is to conduct the heat generated by the gas, so the better the thermal conductivity, the better the heat exchange effect will be. However, the processing of stainless steel heat exchange tubes is difficult, and the internal structure and welding process requirements are also very high. If you are not careful during the processing and manufacturing process, it may affect the manufacturing of the whole machine, so the manufacturing process is risky.
304 stainless steel can be used for stamping and bending, and will not appear heat treatment hardening.
304L stainless steel has good weldability, and can maintain excellent intergranular corrosion resistance after welding or stress relief. Compared with 304 stainless steel, it has higher thermal shock resistance and can make the quality of the whole machine more stable and reliable.
The above is the introduction of the two commonly used materials for stainless steel heat exchange tubes.
