AMS 5629 AMS 5864 BMS7-332 ASTM A564 XM-13. 13-8 PH is a martensitic precipitation-hardening stainless steel. This alloy is double melted in a Vacuum Induction Furnace (VIM) followed by Consumable Electrode Vacuum Melt (CEVM or VAR); or in some cases, 2nd melt is by Electroslag Remelting (ESR) as specified by consumer.
Hot compression tests were performed on the samples of AMS 5643 stainless steel in the temperature range of 900–1050 °C and at strain rates of 10−3–1 s−1. Single peak stress flow behavior was observed at all deformation situations. The flow curves were characterized by a faint peak and slight flow softening which suggested continuous …
