304 stainless steel is one of the most widely used and versatile stainless steel grades, belonging to the austenitic stainless steel family (300 series). It is often referred to as "18/8 stainless steel" due to its composition of approximately 18% chromium (Cr) and 8% nickel (Ni). This composition gives it excellent corrosion resistance, formability, durability, and aesthetic appeal, making it suitable for a broad range of applications.
