AISI 304 vs SS 304: What’s the Difference?

1. Understanding AISI 304 and SS 304

The American Iron and Steel Institute (AISI) assigns numbers to different stainless steel grades based on their chemical composition and mechanical properties. AISI 304 is a specific designation under the AISI standard, whereas SS 304 (Stainless Steel 304) is a general term used globally.

In essence:

AISI 304 is the specific technical name given by AISI.

SS 304 is a generic term referring to the same material used in various applications worldwide.

2. Chemical Composition
