Carbon influences steel’s hardness and weldability

We excel in providing clients with a wide variety of tubing services. One notable example is tube swaging, which has proven its use for multiple industries. This is a rotary process that produces circular concentric reductions in all kinds of tubes. In addition, it can produce regular forms like squares, hexagons, and octagons.

Steel is one of the main materials people use to create tubing. It may seem like a straightforward material to many. However, it is one you must be careful with to use it correctly. For example, carbon is able to affect the alloys in several ways. We are going to explain how it is able to do so here.

What is carbon steel?

Tube swagingThis is an iron and carbon alloy. Low alloy steel consists of carbon as well as small amounts of other materials up to a maximum of 5% total. Examples include molybdenum, manganese, and chromium.

When you increase the carbon content, the hardness will increase. But, you need to control this as it can turn brittle if it is too hard. Depending on your applications, brittleness could be a major factor. Consider a drill bit you use that breaks right in the middle of a project. This faulty utensil might have broken due to its massive carbon content. The carbon would have made it brittle.

As well as brittleness, rusting, tensile strength, and yield point are all influenced by upping carbon content. So you need to be careful to ensure you get the right level to get the characteristics you want.

The effect on weldability

Increasing the carbon will also lower the weldability. This is particularly true for above 0.25% carbon. Ductility and plasticity are similar. Think about a blacksmith hammering on a knife blade. If too much carbon is there, the metal can break so you won’t be able form it into your final product. If your product does not break, this isn’t necessarily a sign it’s of excellent quality.

Another thing high carbon does is lower air corrosion resistance. This leads to rusting. That can cause complications later on. Speak to us if you require first class tube swaging services.

Carbon equivalency

Due to how essential welding is to numerous applications, it is preferable to calculate the carbon equivalency. The results shall provide you with an idea of the hardness and other characteristics. Plus, it will inform you of the heat affected zone. The results will let you predict whether the two metals you are joining shall be compatible or not. Not to mention, they will tell you if you must take precautions.
