Austenitic (300 series, common applications) is steel alloyed with Chromium and Nickel.
Martensic and Ferritic (400's) are generally Chromium only..........
www.matweb.com is a good site............
..
*** Brian T- 18-8 (304) is a mediocre stainless at best, 25-20-5, or 25-18-7 is much better........ Some of the PH and Duplex Stainlesses are incredibly strong with more resistance than 304...... And it is martensite (only one i), and due to the nickel addition, 304 is considered slightly magnetic......

It might be interesting to know a bit more about how and when stainless steel was first discovered in 1915. You can read some of its history at this research site called FirstMention:

Three different main stainless steels. Magnetic or Ferritic, Martinistic, and Austininic. All of them use Fe as a base. As you go up in quality, you go up in Chrome and Nickel. At the high end, some of the best stainles is 18-8. Chrome/nickel with the remainder Fe. 18/8 is not magnetic and is very resistant to chemicals.

There are various grades of stainless steel so your question as asked cannot be answered completely.
It contains iron, carbon, nickel, chromium and other materials
Check out the stainless steel type of interest for specific answers.

Stainless steel is an alloy of iron and nickel, cobalt, etc. There are many grades of it: 304, 308, 316, etc. It is difficult to machine and work with, but has fairly good resistance to oxidation - rusting (why it's used). If you need a metal with more resistance, you would use Hastelloy, Titanium, Tantulum, but these are MUI expensive to construct with. Cheers.
