I don’t know the meaning for the number of 303, 304 or 316 for the description of stainless steel from stainless steel supplier in China until I’m in this area. Now I can say basic information about the stainless steel. Today I want to show you some properties for 304 stainless steel.
 
T-304 is the most commonly used stainless steel in the world. You can find it in everything from forks and knives to backsplashes. It is used worldwide, machine able with the right techniques, and has good corrosion resistance, but is not for use in salt water environments like the wholesale 316L stainless steel. This material is hard enough which is able by cold work.
