13-8PH steel is a martensitic precipitation age-hardenable stainless steel that exhibits good resistance to stress corrosion cracking. It has high strength and good ductility, which are developed by a single low-temperature heat treatment. This stainless steel is tough and ductile in both the transverse and longitudinal directions in large sections. It is useful in environments where high strength, corrosion resistance, toughness, and stress-corrosion cracking resistance are important requirements.
13 8 stainless steel has better transverse toughness properties due to its low carbon content, tight chemical composition control, and vacuum melting. It is a tough-machining stainless steel and is best machined in the H1150M condition. Its speeds must be roughly 25 percent lower for an optimum finish and tool life.
It can be formed with the use of conventional techniques with a 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.
13 8 stainless steel is popular in aerospace applications, including shafts, valves, landing gears, and structural sections. It is also helpful in a wide variety of other applications, such as:
