What is the coefficient of thermal expansion of weathering resistance steel?

Answer 1

steel pipe expands at .0000067 per deg. per foot example a steel pipe 100 ft.long at 30F when heated to 80F will be EL=expansion length L1=original length t2-t1=temp change CE=coefficient of expansion L2=final length EL=100(80-30)x.0000067 100x50x.0000067=.0335 or 3/8" (approx.) L2=100ft. 3/8in.

Pipeline thermal expansion elongation of the formula:

Where: linear expansion coefficient of carbon steel 12X10-6 / ℃

△ L = (t1-t2) L

△ L- pipe thermal expansion elongation (m) - medium temperature (℃) linear expansion coefficient of carbon steel 12X10-6 / ℃ t1- pipeline running temperature (℃) t2- during pipeline installation, L- computing length (m) pipe section

△ L = a (t1-t2) L a-- linear expansion coefficient of carbon steel 12X10-6 / ℃

Answer 2

304:

CTE, linear 20°C 16.9 µm/m-°C 0 to 100°C

CTE, linear 20°C 18.7 µm/m-°C to 649°C

and 316L:

CTE, linear 20°C 16 µm/m-°C 0 to 100°C

CTE, linear 20°C 19.9 µm/m-°C to 871°C

if you want better CTE in an oxygen free environment, try carbon fibre (-1 to +1 µm/m-°C, parallel measurement). Or 'till 450°C at normal atmosphere.

Answer 3

All material expansion coefficientsare in length/length/Celsius or length/lenghth/Fahrenheit; i.e units of 1/C or 1/F

For example, steel may be 17E-06/C ( m\m/C)

the length unis make no differnceas they cancel out: in/in or m/m, etc.

To convert from C to F divide by 1.8

Answer 4

For series 300 (18-8) austenitic stainless, expansion is 16.9 ppm/C.

For the less common 400 series ( Martensitic) , expansion is about 10.0 ppm/C

ppm = parts per million; C =celsius; for F (Fahrenheit) divide values by 1.8

Answer 5

6.8x10-6 µin/in-°F for 0-212 F
