AISI E9310 Corrosion Resistance

AISI E9310 steel also has exceptional corrosion resistance. This makes it ideal for components that need to withstand harsh environments or where exposure to chemicals is likely. Common applications include fasteners exposed to seawater or oil; aircraft parts in contact with salt spray; marine equipment exposed to water or humidity; fuel pumps in contact with gasoline; and valves exposed to caustic solutions or acids.

AISI E9310 Heat Treatment & Machining

AISI E9310 steel is designed to be heat treated at relatively low temperatures (between 1020°F – 1150°F). This allows it to retain its strength while still achieving optimal machinability. Properly hardened components can be machined using standard tools without excessive wear or breakage. Special care should be taken when cutting hardened material as the cutting forces are higher than those associated with softer materials like aluminium or mild steel.


In summary, AISI E9310 steel has excellent wear resistance combined with superior tensile strength, which makes it an ideal material for components that must withstand extreme levels of stress or strain. Its corrosion resistance also makes it suitable for use in harsh environments where exposure to chemicals is likely. Finally, its low-temperature heat treatment ensures optimal machinability so that components can be easily machined using standard tools without excessive tool wear or breakage. If you’re looking for an alloy that offers excellent performance in a variety of industrial applications, then AISI E9310 may just be what you’re looking for!
