Hi,
ASTM (www.astm.org) has a huge number of standards which include 304 SS.  E.g., for every form (bar, forgings, plate, pipe, sheet, tubing, wire, etc.).  Below are those with 304 stainless in the title.


A1022-01 Standard Specification for Deformed and Plain STAINLESS Steel Wire and Welded Wire for Concrete Reinforcement
A813/A813M-01(2005) Standard Specification for Single- or Double-Welded Austenitic STAINLESS Steel Pipe
A814/A814M-05 Standard Specification for Cold-Worked Welded Austenitic STAINLESS Steel Pipe
F593-02e2 Standard Specification for STAINLESS Steel Bolts, Hex Cap Screws, and Studs
F594-02 Standard Specification for STAINLESS Steel Nuts
G108-94(2004)e1 Standard Test Method for Electrochemical Reactivation (EPR) for Detecting Sensitization of AISI Type 304 and 304L STAINLESS Steels

If you are only concerned with composition, this is the one:

Yes, to need a product form.  ASTM specs aren't alloy specific, each one covers a number of related grades, but they are product form specific.

Corrosion, every where, all the time.
Manage it or it will manage you.

The most common ASTM spec for plate, sheet, and strip is ASTM A240.  The most common ASTM spec for bars and shapes is ASTM A276.

Hi,
  just a quick question, what does the AISI stand for in AISI 304 or other steels?
thanks in advance

American Iron and Steel Institute, which used to maintain a register of carbon and stainless steels.  They no longer do this, so the letters AISI should not be used anymore.

Cory
