Comparison between alloy steel pipe and carbon steel pipe

Alloy steel pipe is based on carbon steel pipe. In order to improve the performance of steel, some alloy elements of steel will be added during smelting. Compared with carbon steel pipe, the mechanical properties and hardenability of alloy steel pipe are better than carbon steel pipe, and alloy steel pipe also has physical and chemical properties.

Carbon steel pipe mainly refers to the case that the carbon content is less than 2.11% without adding alloy elements intentionally, and the carbon content is one of the most important factors affecting its strength. , hardness increased, but ductility, toughness and weldability decreased.


The specific functions of carbon steel pipe and alloy steel pipe are listed below for your reference

Alloy steel


1. refractory


2. High production cost

3. High tempering stability and hardenability

4. High strength and toughness

5. Can meet special requirement

Carbon steel tube

1. Easy to smelt

2. Low production cost, but widely used

3. It can be strengthened by heat treatment

4. Poor tempering stability and hardenability

5. Low strength and toughness
