Question d
State the main difference between low carbon steel and high carbon steel.
Worked Solution & Example Answer:State the main difference between low carbon steel and high carbon steel. - Leaving Cert Engineering - Question d - 2010
Step 1
Percentage content of carbon
Answer
The primary difference between low carbon steel and high carbon steel lies in their carbon content. Low carbon steel typically contains up to 0.3% carbon, while high carbon steel contains approximately 0.6% to 1.4% carbon. This variation in carbon percentage significantly affects the properties and applications of the steels.
Step 2
High carbon steel can be hardened throughout
Answer
Another important distinction is that high carbon steel can be hardened throughout its structure through heat treatment, making it suitable for applications that require high strength and durability. In contrast, low carbon steel does not achieve the same levels of hardness and is primarily used for applications where ductility and weldability are crucial.
