Difference between titanium plate and stainless steel plate

If it is a pure titanium plate. It shows that it is only composed of titanium, a chemical element. Titanium is very light. Commonly used in aviation. medicine. And resistant to corrosion. So the value is more expensive.
Stainless steel is much cheaper. It is also more versatile. Why stainless steel is not easy to rust, it is related to adding more than 12.5%  chromium to steel. In the oxidative corruption incapable corrosion medium, chromium can quickly form a dense passivation film on the surface of the steel to prevent the metal substrate from being damaged. When the chromium content is above 12.5%, a dense and stable passivation film is formed, and the rust prevention performance undergoes a step-wise consolidation, and the rust resistance is greatly enhanced. This is why the chromium content in stainless steel needs to be 12% The reason above.
Commonly used stainless steel materials are 304 chemical element is 1Cr18Ni9Ti, where 1 seems to refer to the carbon content. Cr18 refers to the content of chromium. Ni9 refers to the content of nickel Ti, which is the titanium of the titanium plate you said above. Very little in stainless steel.
