Special Steels

Special steels have higher strength and toughness, physical properties, chemical properties, biocompatibility and processing capabilities than ordinary steel.

Generally classified as steel that is composed of special alloys, produced by a special process, or has special properties, to meet specific requirements, special steels display excellent strength and toughness, resistance to stress corrosion and oxidisation and are commonly used across the aerospace, defence and high technology industries.

Special Steel S80

A 16% chromium stainless steel modified by the addition of nickel in the British Standard Aerospace series of alloys.

S80 is used where high mechanical properties are required, and where corrosive conditions are not too severe.

It is one of the most corrosion-resistant grades of martensitic stainless steels, displaying excellent strength and toughness, resistance to stress corrosion and oxidisation.

Special Steel S80 Key Properties

  • High strength
  • Toughness
  • Oxidation resistance
  • High corrosion resistance

Special Steel S130

Special steel S130 is an austenitic 18/9 chromium-nickel stainless steel in the British Standard Aerospace series of alloys.

S130 is used for heavy-welded assemblies which cannot be annealed after welding and where corrosive conditions can affect aircraft components. It is often used in the defence and high technology industries.

Special Steel 130 Key Properties

  • High strength
  • Corrosion resistance
  • Good oxidation resistance

Special Steel S143

A precipitation hardening, aerospace-grade stainless steel, S143 combines high mechanical strength with moderate to good corrosion resistance in a variety of applications.

It is used for mechanical components in aerospace and defence and high-tech mechanical projects.

Special Steel S143 Key Properties

  • High mechanical strength
  • Good to moderate corrosion resistance
