Advantages and Disadvantages of Carbon Steel (Mild Steel)

8/1/2018· Mild steel is the type of carbon steel that has lower levels of carbon in it. When the carbon content in the alloy is 0.05 to 0.309%, it is considered as the mild carbon steel. If the presence of carbon content exceeds the maximum limit of mild steel, it is termed as medium carbon steel which is further followed by high-carbon steel and ultra high carbon steel.

Top 5 Advantages of Mild Steel | Austen Knapman Cut …

The least expensive of all steel types, many everyday objects are created using mild steel, including auto-mobile chassis, motorcycle frames and a great deal of cookware. The secret behind its affordability is its carbon content; ranging anywhere between 0.16% and 0.29%, this middle point of the carbon count range means it''s strong enough for many jobs without being expensively tensile.
