Titanium iron classification and use

July 05, 2023

Titanium iron name and English

Ferrotitanium

Titanium iron use

Used as a deoxidizer and degassing agent. The deoxidation capacity of titanium is much higher than that of silicon and manganese, and the segregation of steel ingots can be reduced, the quality of ingots can be improved, and the yield can be improved. Used as an alloying agent. It is the main raw material for special steel grades, which increases the strength, corrosion resistance and stability of steel. Widely used in stainless steel, tool steel, etc. And can improve the performance of cast iron. Used in the foundry industry to improve the wear resistance, stability, and processability of cast iron. Titanium iron is also the raw material of titanium calcium type electrode coating.
