304 Stainless Steel
Grade 304 stainless steel is an austenitic stainless steel and the most commonly used stainless steel alloy. It is specified under ASTM material specifications and contains approximately 18% chromium and 8% nickel, which provide good corrosion resistance and strength.
304 stainless steel performs well in indoor and many outdoor environments with exposure to moisture and mild chemicals but does not contain molybdenum, making it less resistant to chlorides and saltwater than Grade 316 stainless steel.
In fastener applications, 304 stainless steel is widely used for general-purpose assemblies where moderate corrosion resistance is required.
