What’s the affects of alloy elements in steel pipe?

Alloy steel is a steel which has small amounts of one or more elements (other than carbon )such as Manganese,Silicon,Nickel,Copper,Chromium and Molybdenum in addition.This creates an alloy which has specific properties that are not found in carbon steel.

Pipes made of alloy steel have exceptional performance properties.they are generally developed for energy-related applications involving oil and gas drilling and are subjected to stresses in machine parts.Do you know their own properties and affects in alloy steel pipe?  



Manganese is generally used to improve hot ductility. Its effect on the ferrite/austenite balance varies with temperature: at low temperature manganese is an austenite stabilizer, but at high temperatures it will stabilize ferrite.



Silicon increases resistance to oxidation, both at high temperatures and in strongly oxidizing solutions at lower temperatures. It promotes a ferritic microstructure and increases strength.



A critical element to stainless steel.Nickel generally increases ductility and toughness. It also reduces the corrosion rate in the active state and is therefore advantageous in acidic environments.


Copper (Cu)

Copper can be added to decrease work hardening in grades designed for improved machinability. It may also be added to improve formability.


Chromium (Cr)

The most important alloying element in stainless steel to increases their basic corrosion resistance.All stainless steels have a Cr content of at least 10.5% and the corrosion resistance increases the higher chromium content.


Molybdenum (Mo)

Molybdenum significantly increases the resistance to both uniform and localized corrosion.
