The difference between carbon steel pipe and stainless steel pipe

 Stainless steel and carbon steel are a body, both are steel. Steel that contains only carbon is called carbon steel, while stainless steel is steel that has a high alloy content added to prevent rust.
1. The production process is different
Carbon steel pipes are made by piercing steel ingots or solid round steel to form capillary tubes, and then hot rolling, cold rolling or cold drawing.
Stainless steel pipes can be divided into equal-section pipes and variable-section pipes according to the shape of the vertical section. Variable section tubes include tapered tubes, stepped tubes, and periodic section tubes.
Two, the nature is different
1. Carbon steel pipe: It is formed by piercing a steel ingot or a solid round steel to form a capillary tube, and then hot rolling, cold rolling or cold drawing.
2. Stainless steel pipe: It is a hollow long round steel.
Three, applicable to different
The raw material of carbon steel pipe is round pipe billet. The round tube blank is cut by a cutting machine to form a blank with a length of about 1 meter, and then the blank is sent to the furnace and heated by a conveyor belt. The billets are fed into a furnace, where they are heated at a temperature of approximately 1,200 degrees Celsius.
Stainless steel pipe is a hollow long round steel, widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial pipelines and mechanical structural components.
Four, different characteristics
1. Carbon steel pipe: Carbon steel pipe is divided into hot-rolled and cold-rolled (drawn) steel pipes. Hot-rolled carbon steel pipes are divided into ordinary steel pipes, medium and low pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
2. Stainless steel pipe: Brinell hardness is the most widely used standard for stainless steel pipes. The indentation diameter is often used to indicate the hardness of the material, which is intuitive and convenient. However, it is not suitable for steel pipes made of harder or thinner steels.
