What is the difference between stainless steel and titanium?
The commonly used stainless steel material is 304 1Cr18Ni9Ti including 1 chemical elements as carbon content. Cr18 refers to the content of chromium. Ni9 refers to the amount of nickel, Ti, that is what you said titanium plate of titanium. Very few in stainless steel.
Stainless steel is much cheaper. More widely used. Why stainless steel is not easy to rust, and more than 12.5% chromium is added to the steel. In the oxidizing, corrosion free and corrosion resistant medium, chromium can make the surface of steel rapidly produce a layer of dense passivation film, and prevent the metal matrix from being destroyed. When the chromium content is above 12.5%, the passivation film forming a dense layer of stable, real leap forward in the occurrence of rust resistance, corrosion resistance is greatly enhanced, which is why the chromium content in stainless steel to cause more than 12%.
If it's pure titanium. That just by a chemical element composed of titanium. Titanium is light. Often used in aviation. Medical Science。 And corrosion resistant. So the value is more expensive.
