Equations for the Calculation of the Thermo-physical Properties of Stainless Steel

“…ϩ2.82ϫ10 6 /TϪ156 000 ... (11) Liquid: (10) to (13). The uncertainty associated with the calculation of C p and (H T ϪH 298 ) is probably less than 5 %.…”

“…Thermal conductivities have been reported by the following: Bogaard et al 5) for alloys, 304, 321 and 430; Chu and Ho 13) for 410 and 430; Bogaard 14) for 3-series and 631 and Mills 7) for alloys 304 and 316. The values cited below relate to the maximum thermal conductivity.…”

The benefit of high-conductivity materials in film cooled turbine nozzles

“…This can be due to a slightly different value for the thermal conductivity in the experimental and numerical model but the overall trend for the reduction of thermal gradients is confirmed. As shown in [29,30] the uncertainty of the metal conduction for stainless steel is greater than 5%, for the range of temperatures studied in this work. An additional uncertainty is due to estimate of contact resistance between different components that are not been modelled here.…”

Thermo-mechanical properties and regression models of alloys: AISI 305, CK 60, CuBe2 and Laiton MS 63

“…Copper alloy Laiton MS 63 : ρ = 0.0104T + 7.5085 (10) where ρ is the electrical resistivity, (1 × 10 −8 ) m, and T is temperature, • C. The coefficients of determination (R 2 ) are 0.9994, 0.9883, 0.9961 and 0.9841 for AISI 305, CK 60, CuBe 2 and Laiton MS 63, respectively. This indicates that the empirical models for the test alloys can accurately describe more than 98% of the variable range in electrical resistivity.…”

“…Thermal conductivity data for some alloys are available [7]. Thermal and electrical conductivity of aluminium [8] and chromium alloys [9] have been measured and the thermal conductivity and electrical resistivity of eight selected AISI stainless steels (303, 304, 316, 317, 321, 347, 410 and 430) have been studied [10].
