13-8 Stainless Steel

Stainless Steel 13-8 PH (UNS S13800)

13-8 stainless steel with excellent oxidation and corrosion resistance is highly recommended to be used under severe environmental conditions.

13-8 Stainless Steel 13-8 stainless steel, a martensitic precipitation age-hardenable steel, exhibits features like good resistance to stress corrosion cracking. Some of its mechanical properties are high strength and good ductility developed by single low temp heat treatment. This stainless steel grade demonstrates toughness and good ductility both in transverse and longitudinal directions in large sections.

This stainless steel grade is considered in environments where high strength, corrosion resistance, toughness, and stress-corrosion cracking resistance are important requirements in a steel that show minimal directionality in properties. 13-8 also exhibits better transverse toughness properties which are obtained by low carbon content, tight chemical composition control, and vacuum melting.

As an age hardenable stainless steel grade, 13-8 steel can be a tough machining stainless steel. It is best recommended to machine them in a condition H1150M. Its speeds must be roughly 25 percent lower for an optimum finish and tool life. 13-8 steel can be formed with the use of conventional techniques with formability degree limited by its initial yield strength.

This stainless steel grade possesses good fabrication qualities and can be age-hardened as well by single low-temperature treatment. Aging will be increased when cold work is performed prior to aging, especially for low aging temperatures.

13-8 stainless steel is extensively used in aerospace applications including shafts, valves, landing gears, and structural sections.

Other than that, this type of steel is also used in a wide variety of ways such as:

  • Injection molding equipment
  • Nuclear and petrochemical industries
  • Fittings
  • Pins
  • Nuclear reactor components
  • Machined and cold-headed fasteners
  • Worms
  • Lock washers
  • Universal joints
