Yes, C is the correct answer.

Masum said:   4 years ago
Steel contains carbon 0.15 % to 1.5%.

Deepak kumar yedake said:   4 years ago
Typically there is less than 0.4% of carbon in most steels, though it it is possible to have as much as 2%.

So, answer B is correct.

Steel Types.

Mild Steel or Low carbon steel = 0.05-0.25%.
Medium Carbon steel = 0.29-0.54%,
High carbon steel = 0.55-0.95%,
Very High carbon Steel = 0.96-2.1%.

Carbon Steel can be segregated into three main categories: Low carbon steel (sometimes known as mild steel); Medium carbon steel; and High carbon steel.

Low Carbon Steel (Mild Steel): Typically contains 0.04% to 0.30% carbon content. This is one of the largest groups of Carbon Steel. It covers a great diversity of shapes; from Flat Sheet to Structural Beam. Depending on the desired properties needed, other elements are added or increased.

For example; Drawing Quality (DQ) " The carbon level is kept low and Aluminum is added, and for Structural Steel the carbon level is higher and the manganese content is increased.

Medium Carbon Steel: Typically has a carbon range of 0.31% to 0.60%, and a manganese content ranging from .060% to 1.65%. This product is stronger than low carbon steel, and it is more difficult to form, weld and cut. Medium carbon steels are quite often hardened and tempered using heat treatment.

High Carbon Steel: Commonly known as "carbon tool steel" it typically has a carbon range between 0.61% and 1.50%. High carbon steel is very difficult to cut, bend and weld. Once heat treated it becomes extremely hard and brittle.

The given answer is correct. Wherever the type of steel is not given we will assume it as a mild steel.

C is correct I think.

Wrought iron contains ca - 0.05 to 0.15.
Cast iron 1.7 to 4.5.
Steel contains 0.25.

Ans. C is correct.

Steel contains carbon approximately.

0.05% to 0.25% so I think answer '' C '' is correct.

Wrought iron contains .25, Mild steel .7 to 1.5 & Cast iron 2 to 4.5 carbon.
