mild steel



  1. A type of steel in which carbon is the primary alloying element, with the level of carbon contained in a steel being one of the most important factors governing its mechanical properties. Mild steel has no more than 1.65% manganese, 0.6% silicon or 0.6% copper. Mild steel is available with varying levels of formability. The more formable grades are typically more costly than the less formable grades. Also called carbon steel.
