Steel was relatively consistently produced in India and china and Europe by about 300bc. Falcatas, a spanish sword type, made of steel have been dated to 400bc and steel from Noricum was famous during these times. Swords from Noricum have been dated from 300bc and onwards. The quality of the iron ore was essential in those days, so steelmaking was probably restricted to smiths with access to ore from certain rare mines.
steel was became widespread in East Africa at a early date and in nubia in ancient times around 315 b.c. or earlier and more so in later ancient times.
Steel was known in antiquity, and may have been produced by managing the bloomery so that the bloom contained carbon.Some of the first steel comes from East Africa, dating back to 1400 BC in Tanzania.
Iron and steel manufacturing technology was present in the Eastern African nations of Rwanda, Burundi, Kenya, , and others dating back to the 7th century B.C and in Tanzania in earlier. The smelters used to make iron and steel were far superior to that used by the rest of the world.
Until 200 years ago European steel making technology consisted of "bloom" iron production and "cold-blast" steel production. The Haya of Tanzania , Yoruba of Nigeria and a certain of other groups in Africa used technology in their steel furnaces that pre-heated the air to produce carbon steel that was significantly more advanced than European steel
the first piano was made by Bartolomeo Cristafari in 1709. This was because the previous "pianos" did not have a crisp sound. The piano is made of a hard plastic nowadays but can be made of wood. The strings are made of from tempered high-carbon steel, also known as spring steel. Hope this helps!

The first clue that a penny is made of steel would be that it would stick to a magnet. If not, it can't be made of steel. If it does stick, the coin would have to be authenticated by one of the major grading agencies.
