Titanium is a strong deoxidizer. It efficiently impacts the phase composition and morphology of non-metallic inclusions by additionally deoxidizing steel, increases the solubility of hydrogen in steel thus preventing pinholes from appearing in castings
Titanium is a strong deoxidizer. It efficiently impacts the phase composition and morphology of non-metallic inclusions by additionally deoxidizing steel, increases the solubility of hydrogen in steel thus preventing pinholes from appearing in castings.
Depending on its concentration in steels and their chemical composition, titanium form carbides (TiC), sulfides (TiS), carbosulfides (Ti4C2S2) and nitrides (TiN).Carbides increase the hardness of steels to a greater degree. Titanium injected into molten steel forms TiNs forms nitrides as early as during the pre-crystallization and crystallization periods. By binding sulfur and nitrogen and forming infusible particles, titanium not only produces a modifying influence on the process of crystallization but also performs a barrier function as a refiner of austenite grains during processes of heat treatment.
Titanium is used to prevent intercrystalline corrosion when manufacturing corrosion-resistant ferritic and austenitic steels.
Injection of microadditions of titanium into steel promotes fine-grained structure and reduces the tendency of steel towards the formation of hot cracks.
Titanium increases the wear resistance of steels as they resist increasingly the development of plastic deformation at its initial stage and their hardness increases. It also impacts their mechanical properties by not only refining austenite grains but also by reinforcing them and strengthening intergranular bonds.
