Steel, an alloy of iron, carbon and small amounts of other metals, melts at approximately 1370 degrees Celsius. Because the exact chemical composition of different steel alloys varies, the melting point differs slightly depending on its grade.
Steel is primarily iron, which melts at 1510 degrees Celsius. Steel is made by removing all impurities from iron, adding a small amount of carbon, and then adding alloy metals to create different grades. Chromium is added to create stainless steel, which is resistant to rust. Chromium and molybdenum are added to create chrome-moly steel, which is lighter than other steels and used in vehicle manufacturing and welding. All grades of steel have lower melting points than the parent iron.
