What is the material of black steel pipe?

Material of black steel pipe

Black steel pipe is composed of carbon and iron, also known as ordinary carbon steel pipe. Its chemical composition is iron (Fe) and carbon (C) with a carbon content of less than 2%, and also contains a small amount of manganese (Mn), silicon (Si), phosphorus (P), sulfur (S) and other elements. Black steel pipe has good processing performance and plasticity, so it is widely used in construction, machinery manufacturing, chemical industry, light industry and other industries.

Uses of black steel pipe

1. Construction industry: Black steel pipe is usually used for the support and frame of building structures, such as building columns, beams, stairs, etc.
2. Machinery manufacturing: Black steel pipe is used to manufacture mechanical parts, bearings, auto parts, etc.
3. Chemical industry: Black steel pipe can be used to transport fluid media such as chemical liquids, oil and natural gas.
4. Light industry: Black steel pipe is usually used to process into a variety of furniture, shelves and other household items.

Difference between black steel pipe and galvanized steel pipe

There are differences in materials and treatment between black steel pipe and galvanized steel pipe. There is no coating on the surface of black steel pipe, and it has not been treated with rust prevention, so it is easy to rust. Galvanized steel pipes are hot-dip galvanized and coated with a layer of zinc, which can resist corrosion and be more durable in strong acids, alkalis and corrosive media.

In summary, black steel pipes are composed of carbon and iron, and have certain strength and corrosion resistance. They are widely used and can be found in construction, machinery manufacturing, chemical industry and light industry. At the same time, there are differences in materials and treatment between black steel pipes and galvanized steel pipes.
