Cost. Cast iron is often cheaper than cast steel due to the lower cost of materials, energy and labor required to produce a finished product. Crude steel is more expensive to purchase and requires more time and attention to cast.
Possibly one of the most surprising treasures in your home is cast iron cookware. From $15 to $1,500 is the stuff you rarely want to sell at a flea market. Fortunately, cookware is usually marked on the bottom with the manufacturer’s name and catalog or size number.

While it’s the least valuable household scrap metal, it makes up for it in weight. That is why many scrappers cannot avoid cast iron. The cost per pound of this scrap metal can add up pretty quickly, making it worth taking to the recycling yard.
Cast iron is very easy to cast due to its excellent flowability and low shrinkage. Cast steel has lower fluidity and higher shrinkage compared to cast iron. Cast iron is better in terms of corrosion resistance and resistance to mechanical wear. Cast steel is better in terms of shock loads.
Steel is stronger than iron (yield and tensile strength) and also tougher than many types of iron (often measured as fracture toughness). Most common steel grades have allowances less than . 5% carbon by weight.
Iron with a steel content of about 1.5% is high carbon steel. Its density is approximately 7,840 kg/m^3, only slightly less dense than mild steel but denser than cast iron.
The main component of both cast iron and cast steel is the iron element itself. What differs is the amount of carbon present in both forms. The main difference between cast iron and cast steel is that cast iron generally has a carbon content of more than 2% and cast steel has a carbon content of less than 2%.
The value of antique cast iron skillets can start at new prices, but a super-rare Wagner or Griswold pan can fetch up to $1,500 each. A super-rare “spider pan” in mint condition made by Griswold in the 1890s is worth up to $8,000.

The winner. The prices for cast, sheet and extruded aluminum are usually different. You would pay the lowest of what was in the load/pile. I usually throw cast iron and #1 iron together as the price is usually the same.
Most metals with magnetic properties are iron: Metals and alloys that contain iron. These ferrous metals include mild steel, carbon steel, stainless steel, cast iron, and wrought iron.
Because a cast-iron Lodge pan usually costs less than $25 but can almost always be found on sale for just under $15.
