1, improve the stability of steel in high temperature, high pressure, hydrogen.

2, titanium can improve the corrosion resistance of stainless acid-resistant steel, especially the resistance to intergranular corrosion.

3, low carbon steel, when the content ratio of Ti and C reaches more than 4.5, because oxygen, nitrogen, carbon are all fixed, has a good stress corrosion resistance and alkali brittleness resistance.

4, adding titanium to steel with a mass fraction of chromium of 4%-6% can improve the oxidation resistance of steel at high temperatures.

5, the addition of titanium in steel can promote the formation of nitriding layer, can more quickly obtain the required surface hardness. Titanium-containing steel is known as "fast nitriding steel" and can be used to manufacture high-precision screws.

6, improve the weldability of low carbon manganese steel and high alloy stainless sodium
