AMS 5864 PH13-8mo Sheet
AMS 5864 is the specification for PH 13-8 Mo steel, requiring it to be a corrosion-resistant steel plate with a composition of 13Cr – 8.0Ni – 2.2Mo – 1.1Al. It is produced using a vacuum induction melting process with consumable electrode melting, followed by solution heat treatment for precipitation hardening.
AMS 5864 PH13-8Mo steel sheet is a martensitic precipitation-hardening stainless steel with excellent strength, high hardness, outstanding toughness, and good corrosion resistance. Its good transverse toughness is achieved through strict chemical composition control, low carbon content, and a vacuum melting process.

Processing Characteristics
Machinability
In the solution-annealed state (Condition A), it has low hardness, facilitating cold rolling, cutting, and other machining processes. Its yield strength of 1308-1339 MPa and elongation of 15.3-16.1% also make it relatively controllable during cold working.
Weldability
It can be welded using conventional methods (such as TIG welding and laser welding) and usually requires no complex preheating treatment. Performance loss in the weld heat-affected zone is minimal.
Heat Treatment Flexibility
By adjusting the aging temperature (e.g., H950, H1000, H1025, H1050, H1100, H1150), the strength and toughness combination of the final material can be "customized" within a wide range to meet the specific requirements of different working conditions.
