Low Carbon Steel vs High Carbon Steel

Steel is defined as an alloy of iron and carbon. There are three different types of steel (low carbon steel, medium and high) which is often categorised according to its carbon content. Each type of steel has different properties which make them best suited to different applications. Commonly used for carbon steel include buildings, gears, shafts, pipeline, fridges, washing machines, blades, springs and axles.

What is Low Carbon Steel?

Low carbon steel, also known as mild steel, it is defined by its low carbon to iron ratio, this is usually less than 0.30% of carbon. Cost-wise, it is usually the cheapest out of the three types to produce. It is also more pliable which makes it useful for applications such as car body panels.

What is Medium Carbon Steel?

Medium carbon steel is a middle ground in terms of carbon content, containing between 0.30%-0.60%. It is stronger and more durable than low carbon steel, but it still offers some ductility

What is High Carbon Steel?

High carbon steel, also known as carbon tool steel, is the highest ratio of carbon compared to iron. It is characterised by having more than 0.60% carbon and under 1.5%. This is the strongest type of carbon steel but much less ductile making it very difficult to cut, bend and weld.
