Steel was known in antiquity and was produced in bloomeries and crucibles. The earliest known production of steel is seen in pieces of ironware excavated from an archaeological site in Anatolia (Kaman-Kalehöyük) and are nearly 4,000 years old, dating from 1800 BC. Horace identifies steel weapons such as the falcata in the Iberian Peninsula, while Noric steel was used by the Roman military. Web15 feb. 2024 · 3. Examine the surface for forging marks, which mild steel often has. Look closely at the surface for marks from hammers and machines. Recognize forging marks as an indication that the piece of steel you have may be mild steel. [4] On the other hand, high carbon steel often has fine lines, or rolling marks, running in 1 direction. 4.
