The Advantages and Application of SUS 309 Stainless Steel
SUS 309 stainless steel is a heat-resistant stainless steel primarily used in equipment and components exposed to high temperatures. It excels in high-temperature resistance, corrosion resistance, and oxidation resistance, making it suitable for industrial equipment that operates in high-temperature environments. SUS 309 is particularly ideal for special high-temperature applications such as boilers, heating furnaces, and chemical industry equipment.
The chemical composition of SUS 309 includes higher levels of chromium (22% to 24%) and nickel (12% to 15%). These elements contribute to its excellent high-temperature performance and oxidation resistance. It also has low carbon content, preventing carbide precipitation, thus maintaining stability at high temperatures. Due to these outstanding features, SUS 309 is an ideal choice for equipment in high-temperature environments.
SUS 309 is widely used in the chemical industry, heat exchangers, boilers, and heating furnaces, especially in applications requiring high-temperature and corrosion resistance. It enhances the reliability and durability of equipment in these fields, improving the efficiency of high-temperature devices and extending their service life.
