Thermal conductivity of 304 SS

In summary, the thermal conductivity of 304 SS is 16.2 W/mK at room temperature, making it a relatively good conductor of heat. It has a higher thermal conductivity compared to other stainless steels, such as 316 SS. The thermal conductivity of 304 SS decreases with increasing temperature, and can be affected by factors such as chemical composition and microstructure. It is typically measured using a thermal conductivity meter or through experiments.

I am trying to decide what alloy I should use in an experimental heat transfer device. I am considering 2 materials- 304 Stainless Steel and SAE 516 Grade 70 boiler steel. I want to choose the material that has the best conductivity characteristics. To be clear, I want the material that has the best thermal transfer rate. Both metals would be approximately .125" thick and would be exposed to a source heat of 1000F.
