These elements are all metals, but their oxides are like "earth", so they are customarily called rare earth. The addition of rare earth in steel can change the composition, morphology, distribution and properties of inclusions in steel, thus improving various properties of steel, such as toughness, weldability and cold workability. Adding rare earth into ploughshare steel can improve wear resistance. The Role of Alloy Elements in Alloy Steel
1. Carbon c: The carbon content in the steel increases, the yield point and tensile strength increase, but the plasticity and impact property decrease. When the carbon content exceeds 0.23%, the welding performance of the steel deteriorates. Therefore, the carbon content of low-alloy structural steel used for welding generally does not exceed 0.20%.
Adding molybdenum to structural steel can improve mechanical properties. It can also restrain the brittleness of alloy steel caused by quenching. It can improve redness in tool steel.
9. Titanium (ti): titanium is a medium strong deoxidizer for steel. It can make the internal structure of steel compact and refine the grain force; Reduce aging sensitivity and cold brittleness- Welding performance.

Alloy steel is called alloy steel when other alloy elements are added in addition to iron and carbon. Iron carbon alloy formed by adding one or more alloy elements on the basis of ordinary carbon steel. According to the different elements added and the appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic, etc. can be obtained.
