Difference Between Carbon Steel and Stainless Steel Pipe

Both carbon steel pipe and stainless steel pipe are popular for a wide variety of applications. They are both made with carbon, iron and some other elements. But they have different features, for example, appearance, corrosion resistance, service life, price, etc. Below let’s review the main differences between them.

Carbon Steel and SS Pipe

1. Ingredients

Carbon steel pipe uses carbon steel as raw material, which is mainly made of iron and 0.12-2.00 percent carbon. While stainless steel tube uses stainless steel as base material, which contains iron, carbon, and at least 10.5% chromium content.

2. Anti-corrosion Properties

Stainless steel contains a large amount of chromium. Chromium reacts with oxygen and then forms a passive layer to protect the steel from corrosion. While carbon steel pipe will rust easily. But carbon steel is known for its strength and ability to withstand very high temperatures. You can choose suitable tubes according to the use environment and the expected service life.

3. Price

Comparatively speaking, carbon steel pipes are more affordable than stainless steel pipes. But SS tubes are more long-lasting and corrosion resistant. In the long term, SS tubes will be more cost-effective. You can choose according to your budget and the use environment.

4. Appearance

In terms of appearance, stainless steel tube has a very shiny surface. It retains its luster even when exposed to weather and other elements. Carbon steel pipe is darker in color and has a matte appearance. If carbon pipe is exposed to harsh environments, it will deteriorate in appearance with corrosion.

Which One Is Better, Carbon Steel or Stainless Steel Pipe?

If you are torn between choosing carbon or stainless steel pipe, you can ask yourself the following questions.

1. Are Your Pipes Used At Extreme Temperatures?

Carbon steel pipe can withstand high temperatures and is suitable for use in steam pipes and other applications. However, if your project is in an extremely cold environment, carbon steel pipe will be not an ideal choice. You can choose 304 stainless steel pipe, which is resistant to low temperatures up to -196 degrees Celsius. While SS tube can also withstand high temperatures. Therefore, it is also widely used in kitchen items.

2. Do You Want to Use the Steel Pipe in the Food Industry?

If your project is related to the food industry, stainless steel pipes will be more recommended. The reaction of carbon steel with food can change its taste or may cause health problems. While stainless steel pipes are found everywhere in the food industry and do not affect human health.

3. Will the Steel Pipes Be Used in Corrosive Environment?

Corrosion will greatly influence the service life of your pipeline. In corrosive environments, such as chemical industry, marine, humid surroundings, stainless steel tubes or galvanized steel tubes will be more durable to use and also easier to maintain.

4. How About Your Budget?

Carbon steel pipe is a low cost and affordable option. If you have a tight budget, then carbon steel pipe may be a good choice. But stainless steel tubes are durable to use. In the long term, SS pipes are more cost-effective. So please remember, do not rely on the price only. Welcome to contact us for more professional tips.
