Sorry but this is not so. There are many different grades of stainless to 
serve many different purposes.  440C for instance is the hardest form of 
stainless. It is used for the making of gears and ball bearings and a magnet 
can stick to it and it can corrode. This is the result of it having a higher 
carbon content. Where as 304 /304L has a lower carbon content to it give it 
more weldability. On the other hand, 316/316L has a higher molybdenum content 
so as to have a higher resistance to corrosion and pitting. Each type of 
stainless is used to serve different applications, therefore it has different 
characteristics.
