Do you know which materials are more common for stainless steel heat exchange tubes? Next, Mingxin Stainless Steel will introduce you accordingly.
Zhejiang Mingxin Stainless Steel Co., Ltd. is a modern stainless steel pipe manufacturing enterprise integrating scientific research, production and sales. We have several cold drawing production lines, as well as multiple cold rolling units, CNC lathes and processing centers, mainly producing seamless pipes, bright and annealed pipes, heat exchange pipes, pipe fittings, flanges and other products. Our motto is quality first, Integrity-based, we have established long-term and stable development visions with users from various industries at home and abroad.
There are two common materials for stainless steel heat exchange tubes, 304 and 304L stainless steel.
1. 304 stainless steel: 304 stainless steel is a kind of stainless steel widely used in stainless steel heat exchange tubes. The core function of stainless steel heat exchange tubes is to conduct the heat generated by the gas. The better the thermal conductivity, the better the heat exchange. However, 304 stainless steel has good thermal conductivity, and the processing of stainless steel heat exchange tubes is very difficult, and its internal structure and welding process requirements are very high. Craftsmanship 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, and it can still maintain excellent intergranular corrosion resistance after welding or stress relief, 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 two materials described above are more common in the application of stainless steel heat exchange tubes.
