# Thermal expansion for Stainless & Carbon

## Thermal expansion for Stainless & Carbon

(OP)
Is there any difference in thermal expansion for Stainless steel and carbon steel. If yes please advise me what is the difference in percentage?

Babu

### RE: Thermal expansion for Stainless & Carbon

Yes there is, please look to results as per herunder schedule:

Temperature      E1         E2         E3
200 C            3.4        2.41       2.24
300 C            5.19       3.80       3.56
400 C            7.12       5.34       4.88
500 C            9.16       7.00       6.36
600 C            11.23      8.67       7.81

Where :
E1 : Expansion in mm\m for 18/8 Stainless steel.
E2 : Expansion in mm\m for Low Cr.Mo.( up to 3% Cr)Carbon steel.
E3 : Expansion in mm\m for Intermediate Cr.Mo.(5%-9%)Carbon steel.

You can interpolate to find a mathematical formula

I hope the above is helpful,

BYYYY
