304 stainless steel is an austenitic iron-based alloy containing 18–20% chromium and 8–10.5% nickel, representing the most widely used stainless steel grade in industrial applications. It offers excellent corrosion resistance across a broad range of chemical environments and is readily weldable and formable, making it the default choice for applications requiring durability without specialized high-temperature or high-strength demands. Engineers select 304 over ferritic alternatives when corrosion performance is critical, and over duplex or precipitation-hardening grades when cost, ease of fabrication, and reliable room-temperature toughness are prioritized.
