304 / 304L Stainless Steel Sheet, Coil & Plate - AMS 5513, AMS 5511

304/304L Coil
304/304L Sheet
304/304L Plate

304 / 304L stainless steels contains a higher chromium and lower carbon content than other variations of type 302. 304L is an even lower carbon version of 304.  Both 304 and 304L can be used in the welded condition as opposed to the annealed condition and still maintain resistance to corrosion and lend themselves to many types of fabrication.  

We supply 304 / 304L sheet and plate in a variety of lengths and widths and can custom cut to your exact specifications. 

Available thickness ranges from .007"-2.5".  All of our 304 / 304L sheet, coil, and plate is ordered to specific decimal thicknesses. Please contact us for more details.

Also Available 304 9% Nickel in the following thicknesses:

  • .008 (in)
  • .010 (in)
  • .012 (in)
