Stainless Steel: 1.4301 (304) Bar and Section

Stainless steel types 1.4301 and 1.4307 are commonly known as grades 304 and 304L, respectively. Type 304 is recognized as the most versatile and widely used stainless steel. It is sometimes referred to by its old name, 18/8, derived from the nominal composition of type 304 being 18% chromium and 8% nickel. Type 304 stainless steel, an austenitic grade, is highly suitable for severe deep drawing applications, making it the dominant choice in various applications such as sinks and saucepans. Type 304L is the low-carbon version of 304, employed in heavy gauge components for enhanced weldability. Some products, including plate and pipe, may be available as “dual certified” material meeting the criteria for both 304 and 304L. For high-temperature applications, the high carbon content variant, 304H, is available.
