Separating stainless steel from carbon steel

The thing about tubing is that one size and shape is not going to work for every situation. This is why we have numerous sizes and types of stainless steel ERW tube available. With such a broad range, it is easier to satisfy the diverse needs of clients in various industries. So, whether you are looking for rectangular, square, oval, or round tubing, or big or small diameters, you can find it at Union Steel Tubes.

We have a great level of knowledge when it comes to stainless steel. Therefore, we can easily help any clients looking to understand the difference between it and carbon steel. This is a question we get quite often. Luckily, we can offer advice and help clients to choose the right material for their tubing. Read on to find out more about the differences and which type of steel to use in various scenarios.

Alloying materials

ERW tubeOne area with differences is in alloy materials. General steel is a combination of carbon and iron. The carbon percentage can shift depending on what grade you are using. For the most part, it is between 0.2% and 2.1% by weight.

Even though carbon is the principal alloying substance, certain other elements like manganese, chromium, and tungsten can also be in steel alloys. Different amounts and types of alloying elements decide the tensile strength, ductility, and hardness of steel.

With carbon steel, you can tell right away what the main element is. There can be smaller amounts of other elements though, including silicon and molybdenum. There are different options here including low and high carbon steels. While it may only be a difference of around 1% carbon between the two, it can have a big impact on strength and ductility.

As for stainless steel, it possesses a huge chromium content that produces an invisible layer on the metal. This prevents staining and corrosion. You won’t find an oxide layer in carbon steel so you need to think about corrosion.

Distinguishing the metals

Next, we will talk about how you can distinguish the two. Stainless steel is lustrous and comes in all sorts of grades. Each one though will be relatively reflective. Grades with a higher chromium content can be almost like a mirror in terms of reflectiveness.

The carbon steel on the other hand has a dull, grey matte finish. You can compare it to wrought iron fencing or a cast iron pot.
