What are the most common materials used for stainless steel heat exchange tubes?
There are two commonly used materials for stainless steel heat exchange tubes: 304 stainless steel and 304L stainless steel. The following is an introduction for everyone.
First talk about 304 stainless steel, which is widely used in stainless steel heat exchange tubes. The core function of the stainless steel heat exchange tube is to transfer the heat generated by the gas. The better the thermal conductivity, the better the heat exchange effect. 304 stainless steel conducts heat very well.
Because the processing of stainless steel heat exchange tubes is difficult, and its internal structure and welding process requirements are very high, if you do not pay attention during manufacturing, the quality of the whole machine may be affected, so the production process is risky. 304 stainless steel can be used for hot processing such as stamping and bending without heat treatment hardening.
Next, talk about 304L stainless steel, which has good welding performance, can maintain excellent intergranular corrosion resistance after welding or stress relief, and has higher thermal shock resistance than 304 stainless steel, making the whole machine more stable and reliable.
These two stainless steel materials are commonly used in stainless steel heat exchange tubes.
