18-8 Stainless Steel vs 304 Stainless Steel
18-8 Stainless Steel is a general term describing stainless steels with approximately 18% chromium and 8% nickel content.
304 Stainless Steel is the most common grade of 18-8 stainless steel, meeting precise chemical and mechanical standards.
In other words:
18-8 stainless steel = a family of stainless steels with ~18% Cr and 8% Ni
304 stainless steel = a specific grade within the 18-8 family, standardized by ASTM and widely used.
Key Points:
Both have excellent corrosion resistance, formability, and weldability.
304 is the standard commercial grade of 18-8 stainless steel used in many industries.
Other grades in the 18-8 family include 302, 309, 310, but 304 is the most versatile and common.
Summary:
"18-8 stainless steel" is a broader classification, and 304 stainless steel is a specific, well-defined grade within that group.
