A numerical method, with which experimental results were processed, was adopted to measure the total emissivity of mild steel specimens at high temperatures. This method is derived from considering the transient thermal energy equilibrium between a steel specimen and its surrounding heating environment. ...
In addition, simultaneous, multipoint, and multitemperature measurements are performed by heating the back of the sample. The emissivity of stainless steel and mild steel measured via this method agrees well with the emissivity measured using a thermocouple. In addition, bead-on welding using a ...
Black Plating to give an Emissivity of .80 or higherWe are currently using a stainless steel pipe section in a machine and would like for the finish to be black. I'm not a plating guru as I usually specify the basics like black oxide, nickel, zinc, hard anodizing, etc. and am ...

With the standard ASTM C835-06 test method, the total hemispherical emissivity of A387 Grade 91 steel, a leading candidate alloy for VHTR structural applications, was measured under four distinct surface conditions: (1) mild abrasion following electrical discharge machining, (2) increased surface ...
