Material hardness level effectiveness on thermo-conductively
Material hardness level effectiveness on thermo-conductively
(OP)
Greetings,
Does the hardness level of mild and stainless steel have any effect on the thermo-conductively properties?
Concerned heat exchanger manufacturer.

To corroborate what EdStainless has said, here is a table from the literature showing some values:
HV Hardness Thermal cond.
kg/mm2 W/(mK)
Plain CS low strength 140 16
Ditto high strength 220 25
LCS hardened AISI 4340 560 42
Martenisitic (Cr-Ni) 630 (17-4 PH) 470 17
Austenitic (Cr-Ni) AISI 304 160 16
AISI 316 160 16
Tool steel M-2 Hardened (830-930) 21.3
