Why we call carbon steel pipe?
Carbon steel pipe mainly refers to the carbon fraction is less than 2.11% without containing deliberately added alloying elements of steel, with the level of carbon contained in a steel being one of the most important factors to be influence on it’s the strength of the steel, the hardness increases, but reduces ductility, toughness and weld-ability.
Why we call alloy steel pipe?
Alloy steel pipe is based on the carbon steel pipe, in order to improve the performance of steel, it will add some alloying elements of steel when smelting. Compared with the carbon steel pipe, the mechanical properties and harden ability of alloy steel pipe is better than the carbon steel pipe, the alloy steel pipe also have physical and chemical properties.
The features of carbon steel pipe and alloy steel pipe is listed below for you reference.
Carbon steel pipe
1. Easily smelting
2. Low production cost but widely used
3. Can be strengthened by heat treatment
4. Poor temper stability and harden ability
5. Low strength and toughness
6. Can not meet the special requirements
Alloy steel pipe
1. Hard to smelting
2. Production cost is high
3. High temper stability and harden ability
4. High strength and toughness
5. Can meet the special requirements
