First, the treatment of carbon steel pipe before storage

In the petroleum field, carbon steel pipe is mainly used in oil well pipe, oil and gas transmission pipe, oil field casing and so on.

​The type of material of carbon steel pipe fittings, the higher the carbon content, the greater the hardness, the higher the strength, but the plasticity is lower, the first means that the mechanical properties depend on the carbon content in the steel, and usually do not increase a lot of alloying elements of the steel, sometimes called carbon steel or carbon steel, carbon steel is also called carbon steel.

304 steel will also have magnetism and cannot judge the advantages and disadvantages of stainless steel
