Re: Mill Scale on Welding Table. Yes, you will need to remove the mill scale if you attempt to ground thru the table top. Mill Scale is not electrically conductive when it comes to grounding.....With a decent ground you can weld thru it, better to just remove it from both ends of your weld circuit. Don't bother if you attach your work clamp to ...

Mill scale is the flaky surface of hot worked steel and is formed by the oxidation of the steel surface during reheating, conditioning, hot rolling, and hot forming operations. It is one of the wastes generated in steel plants and represents around 2 % of the produced steel. It is a hard brittle coating of several distinct layers of iron oxides ...

Mill scale is iron oxide that forms on a surface during hot rolling of steel. During rolling, the high temperature involved causes oxide to form over the entire surface, which only increases in quantity as the rolling process progresses. The spots are often hard, but at the same time very brittle.

I live in Oregon and we use Scribner scale. As for overrun, when I am cutting dimension lumber out of Douglas fir, I count on getting at least 35% overrun on short logs. If logs are scaled long (in this area a common length for a long log is 42 fthis is the length most of the big mills want), I will get from 100 to 200% overrun.

Mill scale is bluish black in colour and is usually less than one mm thick. Until last decade, solid wastes produced by integrated steel plants were called waste, but now this term is replaced as byproduct due to intrinsic utilization of these wastes. 6 It is possible to use this mill scale for pure iron powder production.
