While every steel is an alloy, they are not all alloy steel. The difference is subtle: both are mixed with other metals, mainly carbon, but alloy steel is a mixture of carbon and other metals. Common additives beyond carbon include magnesium, nickel, and chromium.
Most types of steel have a very low carbon content amounting to 0.05 to 0.3% while carbon steel has a carbon content up to 2.5%. Although 2.5% might not sound significant, it produces advantages not found in other types of steel. For instance, carbon steel is stronger than traditional types of steel. This is why carbon steel is a top choice for producing knives, automotive components, tools, railways, and much more.
On the flip side, it’s important to note that carbon steel is much more prone to rust and corrosion than other types of steel. It’s also more difficult to work with. That’s why it’s important to choose carbon steel for the correct projects so you can have the best possible results.
In this steel alloy, carbon is the main added element. It comes in three categories; low, medium, and high carbon.
Is incredibly pliable, easy to work with, and cost-effective. It’s easily weldable and machinable. Low carbon steel works perfectly for projects that don’t have any resistance or strength requirements.
Offers more strength and can be cast into various shapes. It is trickier to weld, form and cut.
Is more durable and wear-resistant than other grades. It’s the most difficult steel to work with.
