We are working with a 310 stainless steel damper in a chamber that can operate at 2000 deg. F. What is the formulas for calculating the expansion rate of plate and solid pipe in this atmosphere.

Thank you

Vocdestroyer,

You can calculate the thermal deformation using the following equation:

Deformation due to temp change =

coefficient of expansion*length*(Final temp - Initial temp)

(coeff.for 310 s.s. = 8.0*10^6 in/in/F)

**CAUTION**

You may want to reconsider using this steel in the environment you described, it sounds like your at the limit.

1900F = max intermittant temperature of exposure
2100F = max continuous temperature of exposure

Hope this helps.
 
Also, don’t forget that the coefficient of thermal expansion changes significantly at higher temperatures.

For Type 310 stainless Steel, the coefficient of thermal expansion is 15.8 µm/m-°C (8.78 µin/in-°F) at ambient conditions, but increases to 19.1 µm/m-°C (10.6 µin/in-°F) at 1000 °C (1830 °F).
