What Is The Difference Between Titanium And Stainless Steel?

Titanium metal and stainless steel are two common metal materials that are distinctly different in many ways. Below I will titanium metal and stainless steel characteristics, uses, and advantages and disadvantages of each - to answer.
1. Characteristics and composition.
Titanium is a lightweight and high-strength metal material, its density is about half of stainless steel. It is mainly composed of titanium and has good corrosion resistance and high temperature stability. Stainless steel, on the other hand, is a kind of alloy material containing iron, chromium and other alloying elements°, and its main characteristic is that it has the performance of oxidation and corrosion resistance.
2. Corrosion resistance.
Titanium has excellent corrosion resistance, can be used in a variety of harsh environments for a long time, such as seawater, acid and alkali. Stainless steel also has a certain degree of corrosion resistance, but compared to titanium, its corrosion resistance in strong acids and high temperature environment is slightly inferior °.

3. Strength and hardness.
Titanium metal has high strength and hardness, and has good ductility and toughness, can withstand large loads and impact. The strength and hardness of stainless steel is relatively low, but it has good plasticity and machinability, easy to process into various shapes.
4. Density and weight.
Titanium has a low density and is relatively lightweight, which makes it an ideal lightweight material choice. Stainless steel has a higher density and is relatively heavier.
