Aerospace Special Grades

Aerospace Special Grades designed to work at high temperatures, high pressures and to resist the fuel and hydraulic fluids used on board aircraft.

It is typically used for parts requiring corrosion resistance and high mechanical properties up to 315°C.

The proper chemical composition and the manufacturing process promote improved toughness in the transverse direction and good ductibility; these features are obtained by balanced chemistry capable to limit the content of o-ferrite and by consumable electrode remelting practice capable to control a tight inclusion content.

This grade could be multiple melted using AOD practice followed by either vacuum or electroslag consumable electrode remelting.

Aeroval® AIST

Austenitic Stainless Steel stabilized by the addition of Titanium. Since this grade is an austenitic one, it cannot be precipitation hardened; mechanical properties can be increased by cold working only. AIST exhibits good intergranular corrosion resistance.

Aeroval® GL3

Is a solid solution nickel-base alloy. This alloy shows high mechanical properties at temperatures up to 450″C and above 600″C, good corrosion resistance in different environments (mineral and organic acids), as well as good resistance to crevice corrosion, pitting, erosion, intergranular attack, stress corrosion cracking.

These performances are achieved by the combination of Nickel, Chromium, Molybdenum and Columbium. This grade can be subjected to two different heat treatments to achieve appropriate mechanical properties for different applications: annealing (grade 1) and solution annealing (grade 2).

This grade could be multiple melted using AOD practice followed by either vacuum or electroslag consumable electrode remelting.

Aeroval® AN5

Is an iron-nickel-chromium alloy. The elements AI and Ti in an austenitic structure make it aged-hardenable by appropriate heat treatment with increases in strength and hardness. The addition of Molybdenum provides high-temperature stability and reduces high-temperature creep. This alloy has greater resistance to high temperature than low-alloy steel and stainless steel and shows good mechanical properties at temperatures up to 7oo°C.

This grade could be multiple melted using AOD practice followed by either vacuum or electroslag consumable electrode remelting.

Aeroval® TI-GR5

Is the most frequently used Ti-alloy because of its excellent strength-to-weight ratio which makes it particularly suitable for aerospace applications where a good combination of mechanical properties up to approximately 400°C, formability, weldability and toughness is a mandatory engineering requirement.
