Stainless steel heat exchange tubes are now widely used in our lives and in many industries, so do you know the two most commonly used materials for stainless steel heat exchange tubes?
The more common stainless steel heat exchange tubes are made of 304 stainless steel and 316L stainless steel. Let’s talk about the characteristics of these two materials.
304 stainless steel:
304 stainless steel is widely used in stainless steel heat exchange tubes.
The core function of the stainless steel heat exchange tube is to conduct the heat generated by the gas, so the better the thermal conductivity, the better the heat exchange, and the 304 stainless steel has excellent thermal conductivity.
Another point is that the processing of stainless steel heat exchange tubes is relatively difficult, and the internal structure and welding process requirements are relatively high, so there are risks in the manufacturing process, and a little carelessness may affect the quality of the whole machine, while 304 stainless steel can be used for stamping and bending, etc. Thermal processing, no heat treatment hardening phenomenon.
316L stainless steel:
316L stainless steel has very good weldability.
Stainless steel can maintain excellent intergranular corrosion resistance after welding or stress relief, and its thermal shock resistance is also higher than that of 304 stainless steel, making the whole machine more stable and reliable.
The above is an introduction to the characteristics of these two stainless steel materials.
