There are different grades of stainless steel used which are depending on their properties for different applications. Some of them are listed below 200 grade is the cheapest and used for low-tech applications while 300 grade is expensive with good corrosion resistance which is used for high-tech applications.
200 grades: provides good formability but poor corrosion resistance and has a low content of nickel and a higher content of magnesium.
300 grades:is the expensive grade with good corrosion resistance, formability, and wettability. The most commonly used grades for different applications are 304 and 316.
400 grades: commonly used for applications where high heat resistance is required but has poor corrosion resistance. It has high magnetic properties with high carbon content.
Physical vapor deposition as the name describes uses the metal in vapor form to be deposited onto the metal surface. The formation of metal vapor does not require any chemical reaction rather it&#;s a physical method of vapor formation. Physical vapor formation in PVD is done by physical means like heating, induction heating, resistance heating, electron beam, laser, and plasma. PVD finish is precise and accurate because it is an atom-by-atom top-down approach of coating.
