1 Answer

Answer :

Composition: Iron(Fe) – 98.5 to 99.95, Carbon(C) - 0.05 to 1.5 OR Steel consists Iron and Carbon

Classification:

1) Mild or low carbon steel – (0.05-0.3%) - The variety of plain carbon steel, which consists of 0.05 to 0.3% of carbon is known as low carbon steel.

2. Medium carbon steel (0.3 - 0.6) – The variety of carbon steel, which consists of 0.3 to 0.6% of carbon is known as medium carbon steel.

3. High carbon steel (0.6 – 1.5%) – The variety of plane carbon steel, which consists of 0.6-1.5% of carbon, is known as high carbon steel.
