Product Description

Carbon Steel Tube Square Rectangular ERW Pipe Astms235jr S235j0 S235j2 Black Building Material Mill Black Steel Square Pipe/Hollow Section

 

Product Description

Carbon steel pipe is exactly what it sounds like - pipe made from carbon steel, a steel alloy containing iron and carbon. An incredibly durable material, carbon steel pipe is used in heavy-duty industries like infrastructure, shipping and chemical fertilizing.Carbon steel pipe is made of iron, carbon, and other elements. Black steel pipe is made of iron and other elements, but the main difference between the two is that carbon steel pipe has less carbon. This makes it harder and more brittle, but also allows it to be welded, machined, and formed more easily.
