Stainless Steel 309H sheet is a heat-resistant grade of stainless steel alloy. It contains more chromium and nickel than the 304 grade to improve corrosion resistance at higher temperatures. It also has a higher carbon content, further strengthening the material in elevated temperatures. Its composition consists of approximately 21-26% chromium, 12-15% nickel, and up to 0.08% carbon.
Stainless Steel 309H Sheet is known for its excellent oxidation and corrosion resistance, making it ideal for high-temperature applications. Due to its superior forming and machining properties, it is widely used for industrial operations, including welding, fabrications, hot work and food processing. It also has a great strength-to-weight ratio, making it perfect for creating light structures without compromising strength or durability.
