Carbon Steel Pipes and Tubes

carbon steel pipes

Carbon steel is an alloy composed primarily of iron and carbon. The carbon content in this area is 2.1 wt%. The proportions of additional metals in this alloy are not disclosed, however, it does contain manganese. Manganese, nickel, silicon, and copper should make up less than 1.6 percent of the total. Low carbon steel, medium carbon steel, and high carbon steel are the three varieties of carbon steel.

Low carbon steel is ferrite and pearlite with less than 0.25 percent carbon content, resulting in qualities such as lower hardness but higher ductility, toughness, machinability, and weldability, as well as lower cost.

Medium carbon steel is a martensite alloy with a carbon concentration of 0.25-0.60 percent; its qualities are nearly identical to those of high carbon steel, but with a medium aspect. In comparison to both, high carbon steel has a lot of hardness and strength, but it has a lot of ductilities. The carbon content of High CS ranges from 0.60% to 1.250%.

Carbon Steel Properties

All three forms of carbo steel have the same mechanical properties:
High Carbon Steel has a tensile strength of 665 MPa and a yield strength of 380 MPa, with ductility of 10%.
The tensile strength of Medium Carbon Steel is 460 MPa, while the yield strength is 325 MPa, with ductility of 12%.
With a tensile strength of 325 MPa and a yield strength of 180 MPa, Low Carbon Steel has a ductility of 28%.

The chemical property of Carbon Steel is Iron, which accounts for 98.8% of the total, followed by Carbon, which accounts for 0.70 percent, and a few other metals. There are three varieties of carbon steel: low carbon, medium carbon, and high carbon. Now, the carbon content of various sorts varies. Low carbon is associated with lower carbon, and vice versa. Carbon steel is easily distinguished by its black or dark grey colour.

Carbon steel is an alloy metal made up of a variety of elements in varying proportions, with iron and carbon serving as the primary constituents. Carbon is the most abundant element, accounting for up to 2.1 percent of the total.

Manganese up to 1.65, silicon 0.60, and copper 0.60 are the other metals with a ratio lower than carbon. It is true that when the carbon concentration of a metal grows, heat-treating makes it stronger and harder, but this also reduces the metal's weldability. Due to the presence of carbon, the metal has an excellent black appearance.

Carbon Steel Pipe Applications

A pipe is a tube that is used to transport liquids or gases from one location to another. The pipes are available in a variety of shapes and sizes, with diameters ranging from small to large. Because of its hardness and strength, which are necessary for a pipe, high carbon steel is the finest choice for pipes.

Low carbon steels are the cheapest and have the lowest hardness, ductility, toughness, machinability, and weldability. As a result, they're ideal for automobile parts, structural shapes like I-beams, and other building materials.

Medium carbon steels have a medium strength, ductility, and toughness, making them more wear-resistant. Shafts, axles, gears, couplings, and railway components including train rails and wheels are all made of these steels.

Due to their high hardness and strength, but low ductility, high carbon steels are unsuitable for welding. These steels are frequently employed in cutting tools, high-strength wires, and dies due to their exceptional wear resistance.

Uses of Carbon Steel Pipes

The use of carbon steel pipe is determined by the type of carbon steel used, and each type has multiple types or grades. Automobile panels, nails, wires, pipes, etc are made of medium carbon steel. Music wire, springs, and cutting tools are all made of high-carbon steel.
