Cons of Forging with Rebar
A first major con of using rebar for blacksmithing is its unpredictable nature. Most rebar is not made of quality metals and can even contain dangerous fumes when worked. What is this? You can never be sure what the rebar is made of, so final projects can end up brittle.What metals can you not forge?
The carbon percentage of cast iron is around 4.2 wt%, which is the soluble limit of carbon in iron. As a result, while cast iron is resistant to wear, it is very fragile and cannot be forged.What can I make out of rebar?

What is the strongest metal to forge with?
Tungsten vs TitaniumIn terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it's a brittle metal that's known to shatter on impact. Titanium, on the other hand, has a tensile strength of 63,000 psi.
What does Borax do to metal while forging?
A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off, to keep the metals clean during the forging process.Can you forge rebar into tools?
What is the easiest steel to forge?
Forging SteelTypically forging bladesmiths have restricted their steel selection to low alloy steels like 1095, 1084, 5160, 52100, O1, etc. There are a variety of reasons given for why the bladesmiths usually use these relatively simple steels. Often “ease in heat treatment” is a common one.
