Product Description

Carbon Steel Tube/Pipe

Carbon steel tube is made of steel ingot or solid round steel through perforation made of wool tube, and then hot rolled, cold rolled.

Seamless Steel Pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow-liquids and gases(fluids),slurries, powders and masses of small solids.

 

Carbon steel can also be called plain carbon steel or carbon steel, in addition to carbon, it contains a small amount of silicon, mananese, sulfur, phosphorus and other elements, the higher the carbon content, the better the hardness and stength, but the worse the plasticity. 

With carbon content from about 0.05% ~ 2.1% by weight, it is divided into four classes based on carbon content

Low carbon steel: 0.05 to 0.25% carbon content around .

Medium carbon steel: 0.3-0.5% carbon content around with balanced ductility and strength and good wear resistance.

High carbon steel:0.6 to 1.0% carbon content around, and it is very strong, used for springs, edged tools, and high-strength wires.

Ultra-high carbon steel: 1.25-2.0% carbon content around, and it can be tempered to great hardness.
