304 / 304L / 305 Stainless Steel Coil | 18‑8 Series Austenitic Stainless Steel | Premium Corrosion Resistance

🟧 Product Overview

The 18‑8 Series (304 / 304L / 305) is the world’s most widely used stainless steel family, known for:

• Excellent corrosion resistance
• Outstanding formability
• Superior weldability
• Hygienic and easy‑to‑clean surfaces
• Stable performance in a wide range of environments

Each grade serves a specific purpose:

304 — Standard 18‑8 Stainless Steel

• The most commonly used stainless steel worldwide
• Balanced corrosion resistance and mechanical properties
• Suitable for food, chemical, and architectural applications

304L — Low‑Carbon 18‑8 Stainless Steel

• Lower carbon content improves weldability
• Reduced risk of carbide precipitation
• Ideal for welded structures and chemical equipment

305 — High‑Nickel Deep‑Drawing Grade

• Higher nickel content improves deep‑drawing performance
• Excellent for sinks, kitchenware, and formed components

🟧 Available Grades

304, 304L, 305

🟧 Standards

• ASTM A240 / A480
• JIS G4304 / G4305
• EN 10088‑2
• GB/T 3280

🟧 Chemical Composition (Typical)

Element	304 (%)	304L (%)	305 (%)
C	≤0.08	≤0.03	≤0.12
Cr	18.0–20.0	18.0–20.0	17.0–19.0
Ni	8.0–10.5	8.0–12.0	10.5–13.0
Mn	≤2.0	≤2.0	≤2.0
Si	≤1.0	≤1.0	≤1.0

Note: 305’s higher nickel content is the key factor that enhances its deep‑drawing performance.
