I am looking to save some money and order a slab of scrap steel from a local company. My question is what kind of steel should I be asking for to ensure the steel is food grade quality?
Most people recommend A36 steel, which is a fairly common low-carbon steel. As far as I understand it (procured mine through ebay), you just need to work at scraping off the mill scale with some abrasive. Wash, dry, then season like a cast iron pan. After that you should be good to go.
