Heat Treatment

Jethete M152 is supplied in various heat treatment conditions depending on the specification .

Specification	Heat Treatment Schedule	Designation
BS S151	Soften: 670–720°C × 6h, air cool; Harden: 1050°C, air cool; Temper: 650°C, air cool	S151D
BS S159	Soften: 680–700°C × 2h, air cool; Harden: 1050°C × 30 min, air cool; Temper: 560–590°C × 3h, air cool	S159D
AMS 5719	Anneal: 691°C × 6h, air cool; Harden: 1052°C × 30 min, oil quench; 1st Temper: 560–590°C × 1h; 2nd Temper: 538–560°C × 3h	—

Softening/Annealing: Subcritical annealing at 700°C for 6 hours reduces hardness for cold forming processes.
