What is SUS304 Steel?

SUS304 steel, also known as AISI 304, is an austenitic stainless steel characterized by its excellent corrosion resistance, high strength, and good formability. It contains approximately 18% chromium and 8% nickel, which contributes to its robust performance in various environments.

Composition of SUS304 Steel

• Chromium (Cr): 18% - Enhances corrosion resistance.
• Nickel (Ni): 8% - Improves toughness and ductility.
• Manganese (Mn): 2% - Helps in strengthening the steel.
• Silicon (Si): 0.75% max - Offers added oxidation resistance.
• Carbon (C): 0.08% max - Affects overall strength and hardness.
• Phosphorus (P): 0.045% max - Increases corrosion resistance.
• Sulfur (S): 0.03% max - Improved machinability.
