Zhejiang Mingxin Stainless Steel Co., Ltd. is a modern stainless steel pipeline system manufacturing enterprise integrating scientific research, production and sales. The company adopts advanced, efficient and mature production management mode. Leading materials for the production of high-quality stainless steel, to provide reliable and safe stainless steel pipes and pipe fittings for global users.
The materials of stainless steel heat exchange tubes are more common 304 and 304L stainless steel. These two stainless steel materials have their own outstanding characteristics, so that users can choose according to the actual situation. Let me introduce these two materials for you.
1. 304 stainless steel
304 stainless steel is widely used in stainless steel heat exchange tubes. The core function of the heat exchange tube is to conduct the heat generated by the gas. If the thermal conductivity is good, the heat exchange effect will be better. 304 stainless steel has good thermal conductivity, because the processing of stainless steel heat exchange tubes is difficult, and its internal structure and welding process requirements are high. If you do not pay attention during the manufacturing process, it may cause Affect the quality of the whole machine, and the manufacturing process is risky. 304 stainless steel can be used for hot processing such as stamping and bending without heat treatment hardening.
2. 304L stainless steel
304L stainless steel has good welding performance. After welding or stress relief, it can maintain excellent intergranular corrosion resistance, and its thermal shock resistance is also higher than that of 304 stainless steel, which can make the whole machine more stable and reliable.
The above is the introduction of the two commonly used materials for stainless steel heat exchange tubes.
