What Does 304 Stainless Steel Mean?

304 stainless steel is a widely used austenitic stainless steel that consists of:

• 18% Chromium (Cr) – Provides corrosion resistance.
• 8% Nickel (Ni) – Enhances durability and oxidation resistance.
• Low Carbon Content – Improves weldability and machinability.

Key Properties of SS 304:

✅ Corrosion Resistance: Suitable for harsh environments, water systems, and chemicals.
✅ High-Temperature Resistance: Can withstand temperatures up to 870°C (1598°F).
✅ Non-Magnetic: Retains non-magnetic properties in annealed conditions.
✅ Versatile Applications: Used in pipes, flanges, kitchenware, medical equipment, and construction.
