Newbie, factory coat removal

Post by Soter907 »

Fairly new to this I have been trying to find the fast (easiest) way to remove the "coating" that comes from the factory on full sheets of 14ga mild steel. Currently I am trying flap disk but they are being ate up quick and are super slow going. Is there a easier/better way. I am a hobbiest out of my small garage to space is at a premium.

That is mill scale. It is a PITA to remove. Some guys grind and some use a muriatic acid bath. You could also buy P&O (pickled and oiled) that has very little scale.

Yes, check your supplier for cold rolled steel or pickled and oiled, some call it. It doesn't have mill scale but is usually more expensive. But it saves you the grinding/etching time. I soak my pieces in 12% pickling vinegar instead of muriatic acid.

Thank you for the advice. I don't have a great supply but I will ask. Maybe look elsewhere for product

i just wanted to add, P&O and cold rolled are 2 different materials and do not mean the same thing... P&0 is still hot rolled, but using a different process.
