Jethete M-152 AMS 5719
AMS 5719 is a specification of Jethete M-152, which is a nitrogen bearing, hardenable 12% chromium martensitic stainless steel. This specification is characterized by high-temperature strength thanks to the heat treatment that includes double tempering (as supplied by Tech Steel & Materials).
Other properties of AMS 5719 are excellent creep and corrosion resistance, very good toughness, and temper resistance of temperatures up to 1040° F (560° C). Due to these properties, it is mainly used in the aerospace industry for the manufacturing of turbine blades and turbine discs, and other parts used in high heat and high-stress environments.
AMS 5719 is available as bar, extrusion, forging, ring, tubing and wire. The wire can be used for welding of AMS 5719 as well as the AMS 5718 specification.
This particular specification is annealed and then vacuum arc or electroslag remelted using the following heat treatment:
- Annealing at a temperature of 1276° F (691° C) for six hours and then air cooled to room temperature.
- Hardening at 1925° F (1052° C) for 30 minutes, followed by oil quenching.
- First tempering at 1040-1094° F (560-590° C) for one hour, followed by air cooling.
- Second tempering at 1000-1040° F (538-560° C) for three hours, followed by air cooling to room temperature.
