The zinc coating on mild steel protects it from rusting, while black steel will rust over time. Mild steel is more resistant to corrosion than black steel. The zinc coating on mild steel makes it more susceptible to breakage. Strengthīlack steel is stronger than mild steel because it is not as brittle. Mild steel is made of iron that has been galvanized with a thin layer of zinc. Difference Between Black Steel vs Mild Steel Compositionīlack steel is made of iron that has not been galvanized. Due to its low cost and ability to withstand high temperatures, mild steel is often used in automotive manufacturing processes such as engine blocks and exhaust systems. In addition to being malleable, mild steel is inexpensive compared to other metals such as stainless or aluminium alloys. Mild steel has good ductility, meaning it can be easily shaped into various products, including wires, rods, bars, sheets, etc., making it one of the most versatile materials available for industrial use. Mild steel is also known as low-carbon or plain-carbon steel because it contains very little carbon (less than 0.3%). Black steel is also famous for its low cost compared to metal alloys. This type of steel is commonly used to construct bridges, buildings, and other structures that require extreme strength and durability. It is also called “carbon steel” because it contains up to two per cent carbon by weight. What is Black Steel?īlack steel is created through heat-treating and rolling, making it highly durable and resistant to corrosion. For those unfamiliar with these metals, let’s take a closer look at the differences between black and mild steel. Both materials offer a variety of advantages and disadvantages depending on their intended use. However, there are a lot of other considerations that are made when choosing the right type of steel piping.Īs always, for best results, partner with a trusted distributor with a history of supplying projects with the right parts for the job.When it comes to steel, there are two main types-black steel and mild steel. Also, its versatility makes it cost-effective. It also has a higher carrying capacity than black steel pipes with the exact same diameter. This is because it can be made much thinner. This means that if the environment is to be considered, most of these projects might use black steel instead of carbon steel pipe fitting due to its low carbon content.įor any offered pressure, carbon steel piping is cheaper than black steel. There are more than 100 major projects where flanges, piping, and various pipe fittings will be needed in the next five years. Research shows that black steel is more eco-friendly than carbon steel when it comes to CO2 emissions during manufacturing. Making use of steel for pipes is both safer for people and the environment. Hence, it is also used as a scaffolding frame. This pipe is susceptible to corrosion, which is why it requires galvanization.

Carbon steel piping, on the other hand, is mainly used for carrying water into homes and commercial properties. Therefore it is also used in fire sprinkler systems. Also, this pipe is more fireproof than carbon steel piping. This pipe is seamless, and this makes it perfect for carrying gas. Difference in Outlookingīlack steel piping is mainly used to carry gas into commercial buildings. That means carbon steel pipe fitting can be used for applications that require a very high capacity to withstand pressure. Unlike this technique, when making carbon steel piping, it is made in a seamless fashion. Apart from that, black steel piping is made using several grades of malleable iron.

On the other hand, black steel gets its name from the dark-colored iron oxide that is used to coat its surface. CompositionĬarbon steel, as its name suggests, has a high carbon content. Black steel piping, on the other hand, is made from non-galvanized steel and is not susceptible to corrosion. One of the main differences between carbon steel and black steel is that carbon steel piping and carbon steel pipe fitting are susceptible to corrosion. These differences also account for why these pipes are used for different applications. There are several differences between carbon steel piping and black steel piping.
