◉ Product Details
Chemical composition
Physical properties
Material properties
UNS J93403, also known as ASTM Grade HE, is a high-chromium, nickel-rich austenitic stainless steel designed for high-temperature applications requiring excellent oxidation resistance and high tensile strength. This steel is particularly effective in environments where resistance to scaling and high temperature corrosion is essential. It provides an optimal balance between mechanical performance and thermal stability, supporting use in conditions up to 1100°C.
Advantage
Application
UNS J93403 is extensively employed in petrochemical and refining industries for components like furnace parts, heat exchangers, and other systems exposed to high temperatures and corrosive gases. Its durability and performance under thermal stress make it suitable for energy production facilities and high-temperature industrial processes.
