steel heats by color
Quote:
Thanks Karl, This should be very helpful for those working with steel. When the film shows the 1525F for annealing steel - with slow cooling from that temp) - imagine taking mild steel body work to the red heat in a lighted room, and quenching it suddenly with cold water ... and it becomes ... harder. (This film should remove that surprise element. ) Steel heats at colors are listed here: http://www.mooseforge.com/Techniques/heatcolors.html

I enjoy watching just about anything in black and white. Varied shades of red is good too. Both were interesting, thanks.

Good relevant stuff Karl - thanks for posting. Takes me back to my early days at British Steel polishing and etching samples to look at grain structures.
