The primary alloying element in Stainless Steel 321H is titanium (Ti), which stabilizes the steel and prevents carbide precipitation during welding. It also contains chromium (Cr) for corrosion resistance and higher carbon content for increased strength at elevated temperatures.
Stainless Steel 321H is most suitable for high-temperature applications in the range of 427°C to 816°C (800°F to 1500°F). It offers excellent oxidation resistance and stability in these temperatures, making it ideal for heat exchangers and furnace components.
Typical dimensions of a Stainless Steel 321H flat bar range from 3mm to 150mm thickness, 25mm to 600mm width, and up to 6 meters in length. These dimensions vary based on manufacturer specifications and customer requirements.
The Stainless Steel 321H Flat Bar finds its place in various industries that demand exceptional heat and corrosion resistance. It’s commonly used in aerospace, chemical, petrochemical, and power generation sectors, where components frequently operate under high temperatures. This material is perfect for creating exhaust systems, heat exchangers, furnace parts, and boiler tubes. Additionally, it’s suitable for food processing, pharmaceutical equipment, and architectural structures that face harsh conditions. With its blend of mechanical strength, thermal stability, and corrosion resistance, the Stainless Steel 321H Flat Bar from Neith Metals is a top choice for those seeking quality and reliability.
