스테인레스 스틸 열 교환 튜브의 두 가지 일반적인 유형

Stainless steel heat exchange tubes are typically made from either 304 or 304L stainless steel. Below is an overview of these two common materials and their characteristics.

1. 304 스테인레스 스틸

304 stainless steel is widely used in heat exchange tubes due to its good thermal conductivity, which improves heat transfer efficiency. The primary function of these tubes is to transfer heat generated by gases, and better thermal conductivity leads to more effective heat exchange.

하지만, manufacturing heat exchange tubes can be challenging, as their internal structure and welding must meet high standards. Any errors in the process may affect the overall machine quality. Fortunately, 304 stainless steel is suitable for hot processing, such as stamping and bending, without requiring heat treatment or hardening.

2. 304L 스테인레스 스틸

304L stainless steel offers excellent welding performance and retains strong resistance to intergranular corrosion, even after welding or stress relief. 추가적으로, it has greater heat shock resistance than 304, which enhances the stability and reliability of the entire machine.

둘 다 304 and 304L stainless steel are popular choices for heat exchange tubes, each offering unique advantages depending on specific needs and conditions.
