Main Properites
AISI 304	Excellent resistance to corrosion and chemical agents. Can be used in food and medical devices.
AISI 304L	Excellent resistance to corrosion and chemical agents. It is easy to be machined.
AISI 316	Better resistance to corrosion  and chemical agents  and less magnetic than 304 and 304L . Can be used in stronge acids and high temperature inviorement.
AISI 316L	Same performance of resistance to corrossion with 316, but more easier to be machined.
AISI 420	Good resistance to corrosion and can be heat treated.
AISI 420C	Same as 420 with higher hardness.
AISI 430	Its anti-rust performance is between 304 and 420. Ferrite stainless steel. Small coefficient of thermal expansion
AISI 440C	Good resistance to corrosion with higher hadness and better wear resistance.
