Composition and Characteristics
The reliable performance of 304 stainless steel is due to its carefully balanced chemical composition, which typically includes:
Chromium (Cr):18-20%
Nickel (Ni):8-10.5%
Carbon (C):0.08% max
Manganese (Mn):2% max
Silicon (Si):1% max
Phosphorus (P):0.045% max
Sulfur (S):0.03% max
This composition gives 304 stainless steel its key characteristics:
Corrosion Resistance:The high chromium content provides excellent resistance to oxidation and corrosion, making 304 stainless steel suitable for a wide range of environments, including those exposed to moisture, chemicals, and saltwater.
Strength and Durability:304 stainless steel offers good tensile strength and toughness, ensuring that it can withstand heavy loads and resist wear in demanding applications.
