Chemical composition:
Carbon steel welded pipe is mainly composed of iron and carbon, containing less other alloying elements.
Alloy welded pipe, on the other hand, contains more alloying elements, such as manganese, nickel, chromium, etc. The use of these alloying elements improves the mechanical properties and corrosion resistance of steel pipe.
Mechanical properties:
As carbon steel welded pipes have fewer alloying elements, their mechanical properties are relatively low and they are suitable for general and non-critical structural support.
Alloy welded pipe has higher strength and toughness through the addition of different alloying elements and is suitable for more complex and demanding use environments.
Price:
Carbon steel welded pipe has a relatively mature production process and lower cost due to its simple composition.
Alloy welded pipes are more expensive due to the increase of alloy elements and the complexity of the production process.
Application areas:
Carbon steel welded pipes are commonly used in general engineering such as building supports and small structural supports.
Alloy welded pipes are commonly used in bridges, highways, large building structures and other occasions with high requirements for material properties due to their excellent mechanical properties.
