Do you wish to have a Stainless Steel Pipes or carbon steel Pipes for your next project? Selection of appropriate steel type for the next project is the most important decision that you need to make right now. However, before you make any choice between various grades of steel, you first need to select the steel type like where it needs to be stainless steel or carbon steel. This article very well discusses the main difference between stainless steel and carbon steel.

What’s the key difference between the two?

Both carbon, as well as stainless steel, differs only in appearance, mechanical properties, corrosion resistance, and cost. Given below is a detailed step by step guide on each of these-

Appearance– when only the appearance of steel is considered, then the aesthetic appeal does the job appropriately. What kind of steel is preferred in general when it comes to picking through appearance? It is stainless steel that contains particularly a well-established finishing. Despite the fact that both carbon and stainless steel is polished and sanded, stainless steel gives off shiny look and bright. However, carbon steel generally requires or need paint or clear coating as soon as possible after the polishing process. Stainless steel is the best know to regain scratches and carbon steel can be repainted when subjected to corrosion.

Mechanical properties– the mechanical properties are very different for carbon & stainless steel when it comes to picking different grade or types. Ductility is more in stainless steel due to the fact that it holds a large amount of nickel. However, for the brittle grade, martensitic grades are best that comes under stainless steel. Since the carbon steel possesses low carbon, the tensile strength is somewhat different than stainless steel which has increased strength. However, 0.30% carbon by weight makes it heat treatable.

Corrosion resistance- the ability to show resistance toward corrosion causes the main difference between stainless steel and carbon steel. Stainless steel, in general, is more resistant toward corrosion. Since both steel type contains iron within them, when it got exposed to environmental conditions, the creation of rust takes place. The rusting can be protected or prevented via the creation of the chromium oxide layer over the steel. It also helps in corrosion as well as steel degradation. Carbon steel generally has enough chromium thus allowing oxygen to form a bond that would result in rust or iron oxide formation. If you wish to go too far, then stainless steel is the best.

Cost- cost is another important and crucial consideration when it comes to picking between stainless steel and carbon steel. Although both grade types vary drastically in cost, however stainless steel is more expensive compared to carbon steel. It is because of the addition of various alloying elements like nickel, manganese, and chromium. This is responsible for increasing the cost of carbon steel. Carbon steel is not only affordable but also contains carbon elements. If you have a tight budget, then it is recommended to pick carbon steel over stainless steel.

Based on the above factors, you can decide whether your project needs Stainless Steel Pipes or carbon steel Pipes.
